Abstract

 In order to investigation of succese of BLACK LOCUST species PLANTATION in ARAK city, an area covered with forest strip circea 85 ha was selected BLACK LOCUST species was given three treatments including: an area with suitable and organized management and high social effects, an area with moderate irregular management and medium social effects and an area with low and unorganized management with low social effects.Line sampling method was used for forest inventory considering of the area's strip structure.79 samples were taken with 200 m in distance with 200 m2 area for each sample. In each sample, qualitative and quantitative characteristics recorded. T and Turkey tests were applied for quantitative data analysis and also Kruskal-Wallis and Chi-Square tests for qualitative data. Four soil profiles were digged for investigation of soil condition in study area. In each profile, two soil samples (in depth 0-30 and 30-60 cm) were taken to analyze for determination of soil chemical and physical properties.In order to analyze soil characteristics, multi -variable analysis, e.g. principal components analysis (PCA) was exploited. The results show that area with regular management is more fertile than otl; 1ertreatments. The evaluation of PLANTATION success with BLACK LOCUST species is regarded more preponderated considering the quantitative characteristics and PLANTATION establishment indices. But considering the qualitative characteristics and aesthetic issues as well as visual vision are regarded, BLACK LOCUST is generally possessing of more privileges.
