Abstract: 

One of the most important function of obtained information form land use planning, is providing the species plantation trials based on ecological specifications and social- economical conditions in environmental units. In this research, in addition to ecological capability evaluation and using of environmental units by using of systemic analysis, the land use of forestry provided for watershed of Sarab in four different levels. According to mentioned plan, the watershed is out of the first class use for forestry. Measurement belonged to the second, third and fourth class of use resulted in 463,1072 and 670 hectares respectively. Then, by using of ecological specifications table in environmental units, ecological specifications table in specie plantation units, and finally based in this plan and in regard to the ecological limits of tolerance of selected species, the plan of species plantation trials of watershed designed in seven different levels. In total 3700 hectares of watershed and 2205 hectares belonged to forestry. land use, an area equaling to 1400 hectares in seven levels were identified appropriate for implementation the species plantation trials in regard to social- economical problems, land use planning and the other suitable land use. Implementation of this research confirmed that obtained information form land use planning in the area of watershed will be used based on land use planning, forestry land use and the other available information in documentary form for providing species plantation trials. in addition, the importance of extracted information from land use planning, including social- economical factors, wildlife density of canopy and finally land use planning itself along with other obtained information from it, was clearly determined in procedure of selecting species for species plantation trials.
