The area under investigation is Consist of the Zagros Mountain belt and its southern coastal margin. The dominant focal mechanisms in this zone are reverse and thrusting too. In this research, investigation area has divided to 14 provinces by difference in geological characteristics and then, their seismicity parameters have estimated.Therefore, the provinces that have highest seismic activity rate and seismic potential are introduced. In addition, the six main siesmogenic trend with N-S trending are distinguished that one of them (Qatar-Kazerun fault system) has accompanied by surface ruptures.

In this study zoning for the management plan of Kavir National Park (419613 ha, SE of Tehran, Iran) has been implemented. Ecological and socio-economic resources were initially surveyed and mapped (scale 1:50000). Then data analysis as well as integration with system analysis approach was performed. As a result 863 micro-ecosystems were mapped. Ecological capability of mapping unit (MU) was evaluated for:restricted nature reserve, protected area, extensive use, intensive use, rehabilitation, domestic use and culture-historical, with the aid of specified ecological park management models. Finally with coordination of socio-economic data and ecological capability of MU, priority, ranking and arrangements of zones were mapped.The results show that %15.95 of allocated zones is suitable for restricted nature reseve, %33.63 for protected area zone, %35.85 for extensive use zone, %7.82 for intensive use zone, %1.27 for rehabilitation zone, %2.47 for domestic use zone, and finally%3.01 for culture-historical zone.

In this study zoning for the preparation of management plan for Golestan National Park (GNP is the first national park of Iran, with an area 91895 ha) has been implemented. First, ecological and socio-economic resources were surveyed and mapped (scale 1:50000). Then data analysis and integration with system analysis approach were performed. As a result, 775 micro-ecosystems (Makhdoum, 1992) were mapped. Ecological capability of mapping unit (Mu) was evaluated for restricted nature reserve, protected area, extensive use, intensive use, rehabilitation, domestic use, cultural-historical and buffer zones, with the aid of specified ecological park management models (Makhdoum, 1378). Finally with the coordination of socio-economic data and ecological capability of Mu, periority ranking and arrangements of zones were .mapped. The results show that %49.43 of allocated zones is suitable for restricted nature reserve zone, %35.05 for protected area zone, %4.58 for extensive use zone, %0.54 for intensive use zone, %9.91 for rehabilitation zone, %0.11 for domestic use zone, %0.38 for cultural-historical zone and %5.69 for buffer zone (with protected area & rehabilitation zones).

Isfahan is among the cities which has unique formal features in its physical structure.Despite the comprehensive and detailed plans prepared during the recent decades, the role of city scale in controlling and guiding the development of this city has been neglected.One of the most important reasons behind such negligence is the methods used for such planning. The suggested zoning plans, which are land-use based, were not able to use the features of the physical structure as a unique property of the city to improve the quality of the urban spaces. Thus, it is necessary to use a type of zoning which is based on historical and cultural features of the city and apply those qualities during the process of city planning.Transect zoning is a new approach for city scaled zonings. It considers the components of physical structure of the city and decentralization in all aspects, which affect the formal structure of the city in urban planning. According to the above mentioned points, the goals of this study are to introduce zoning transect as a method for zoning lands and cities and to improve the transect zoning to be applied on some part of Isfahan in accordance with the local features and practical usage. The questions raised in this study are: What is transect zoning and what is the function of this method? How is it possible to make a transect zoning for Isfahan? The research method is descriptive-analytical. The results of this study show that features which describe the transect zones can be used for more efficient planning. Based on a formal point of view, these features can be used for changing the local features of the city.

One of the basic discussions in geosciences is construction of different tectonic zoning maps. In conventional tectonic zoning, not only the great amounts of subjective judgment are involved but also accurate interpretation of high-dimensional data is so difficult and out of human capability. To alleviate these deficiencies, quantitative scientific methods in data mining domain can be applied as an effective and useful tool to construct the new numerical maps in geosciences. In this paper self-organizing map.(SOM) neural network that is one of the common methods in data mining has been applied for numerical tectonic zoning of Iran. SOM is an unsupervised artificial neural network particularly adept at pattern recognition and clustering of high-dimensional data. Visualization of high-dimensional data in two-dimensional topological-preserving feature map is another specific capability of SOM that represent both homogeneity within and similarity between clusters. Although there are some similarities between SOM's numerical maps constructed here and the conventional maps but SOM method is more powerful for identification and interpretation of different zones than conventional methods. Utilizing SOM method enables us not only to evaluate the degree of homogeneity in each zone, but also to separate regions zone that experience similar geological evolutionary despite of their geographical locations. For instance Lut and Gavkhuni zones show more homogeneity than Makran and Azerbayejan zones also Kopeh-Dagh and Zagros are located at different regions, they have similar features. The results obtained here represent separation between Makran from East Iranian Ranges and Western Azerbaijan from Alborz Ranges, too. It is important to recognize that the SOM's results are based purely on the geophysical, geological and seismic features presented previously. So correspondences and differences between the SOM's zones and a given zone based on conventional method must receive careful thought.

Land and resource developoment suitability is usually achieved by landscape capability analysis. But using land capability analysis in planning process is often restricted by budget and time limitations. A simple, yet effective capability analysis method is hence required, that can furnish planners reliable land zonning with the least data and time requirement. The Optimum Integration Method (Formann, 1995) of land capability analysis, zonning and classification is one of these simple, yet effective methods.An addapttion of this method was used for a land-use planning project concerning touristic development of Kohkiloye-U-Boyer- Ahmad Province (Southern Iran). Successful achievement of foreseen planning objectives resulted in introducing this method for further possible uses in simillar cases. This environmental capability analysis method in land-use planning process offered both short-term management proposals and long-term planning strategies baseed on actual and preferred land capability and carrying capacity. Furthermore, proper site selection for implementation of pilot development projects was also achieved based on regional and local comparative advantages (and/or disadvantages) of concerning landscapes.

Shiraz is a city known for its tourism-friendly climate and abundant tourist attractions, making it highly favorable for the revival of night tourism, which seeks to increase the duration of visits to Shiraz's attractions during nighttime. The current study sought to analyze the zoning of night tourism within the city of Shiraz, seeking to analyze and assess the tourism landscape, identify the componential elements and dimensions of night tourism, and portray the optimal areas for night tourism within the city. This applied descriptive-exploratory research adopts a quantitative approach, collecting its required data via library and field studies. Moreover, survey and observational tools, including a researcher-developed questionnaire were used when needed to fill informational gaps. The statistical population of the study comprised the city of Shiraz, and the required samples were collected using Comprehensive Enumeration and Expert opinion methods. Moreover, GIS tools were used to analyze the collected data and perform zoning. The results revealed the spatial zoning of Shiraz, encompassing various sectors across multiple regions of the city, including the entirety of 8th District 8 and parts of the other 11 districts of the city. The analyzed regions encapsulate a substantial area of central Shiraz, which urgently requires the development of night tourism to avoid stagnating.

Liquefaction appears in saturation conditions in sandy to silty unconsolidated soils. When seismic loads of earthquakes stresses on suitable masses of soils for liquefaction, these soils tend to reduce their volumes, this leads to liquids trap inside the soil and water in pores pressure increases, so effective shear stress decreases inside the soil and liquefaction appears. This phenomenon during an earthquake can lead to geomorphic changes on the surface of the earth and causes damages on human foundations. Recognizing and zonation of suitable areas for liquefaction alongside by determining risk potential areas can help us to reduce damages during an earthquake. In this research, by using IRS remotely sensed data and overlying digitized layers of geologic and seismic areas, underground water table level, and geomorphologic landform characteristics, a liquefaction zoning map were produced for Silakhor plain west of Iran which shows 7 class of potential risk areas. Based on this map, 7 percent of study area located on very high level risk of liquefaction, 21 percent on risk class 5, 5 percent on risk class 4, 4 percent on risk class 3, 5 percent on risk class 2, 30 percent on risk class 1 and 28 percent on class zero.

Aims & Backgrounds One of the most important incidents of heavy precipitation is the heavy loses. Heavy Precipitation regimes can help to identify the climate of each region. Many economic activities (especially agriculture) are adjusted based on the precipitation regime. Change of precipitation regime, in addition to significant environmental impacts, can affect the habits and economic activities and their incomes. Identification of homogeneous precipitation regions is one of the most important prerequisites for environmental planning, especially resource management and spatial planning programs. This research aimed to zoning the Iranian Heavy precipitation regime over 20 years (1996-2016). Methodology The daily precipitation data of 153 synoptic station were used to zoning the heavy precipitation regime. For implementation of the PCA model, a matrix with the dimensions of 153×12 was created. By analyzing the main components on the matrix, the first six components were selected. The stations were grouped in the six areas of homogeneous heavy precipitation by k-mean clustering of Standard score matrix of selective components. Findings The regime of autumn heavy precipitation had the most factor score among the 6 regimes. The maximum heavy precipitation of spring-summer pattern (second pattern) was in April to July. The third pattern (absolute spring regime) had the highest heavy precipitation in April and May. The fourth pattern of early winter had the highest heavy precipitation in October, November, December, and January. In the fifth pattern, a large part of the heavy precipitation was in the summer. The heavy precipitation maximum of the sixth pattern was in the summer. Conclusion There are 8 regimes of heavy precipitation in Iran which the maximum of heavy precipitation is in the Azerbaijani and north Azerbaijan regimes at the first half of the year and in the other regimes at the second half of the year.

Nowadays, while there are a number of definitions have been introduced for the concept of zoning, there is no general consensus due to different disciplines adopt this term. In the field of planning, the zoning is a conscious and contemplative process to detect homogenous areas by an authority to allocate certain kinds of resources to them. Therefore, the process of zoning is an essential task to allocate and monitor the development projects for different type of territories. In this article, zoning is took into consideration from the rural transportation point of view to find what would be the homogeneous zones of rural transportation for Iran? To answer this question, an in-depth spatial analysis through the Geographical Information System (GIS) is performed with regards to a descriptiveanalytical method. Based on four main indices which are fully explored in the paper (i.e., access to the link road, distance to urban hierarchical levels, rural density and land use), five homogenous distinct zones for Iran is emerged. The resulted zones which are presented on a country map would be useful for future rural transportation planning in Iran.
