Abstract

Forest which is one of the most valuable natural resources, has got a considerable protective role in biological and ecological evolution and its economic and environmental aspects is getting progressively more important. Forest ecosystems, having spent a long time to reach their present situation, play an effective role to keep balance in nature. Unfortunately in spite of these advantages, in theoretical and practical forest management which has figured in forestry plans in the north of Iran, just economic aspects of forest productions has been considered and outdoor recreation uses, environmental affairs, forest site capability and its mutual relationship to economic and social matters are not completely inspected. These parameters are so important and must be recognized in the basin area. On the other hand, industrial development and high rate of population growth has caused many social and environ mental problems such as farming and natural resources reduction so considering sustainability and survival of forest ecosystems in a way which would lead to both suitable economic production and effective environmental roles is an important and vital issues. In the first step of the following research, ecological parameters, consisting of physical parameters (physiography, topography, soil, geology, climate, hydrology and …), biological parameters (vegetation cover and wild life) and socioeconomic parameters were studies and recognized. Then produced data (several maps and reports) were digitized and integrated by geographic information system (GIS). The final information coverage which was obtained from data analysis and integration consists of environmental units and all characteristics of each unit is available in the from of database in the mentioned information coverage. The environmental units were evaluated by designing a specific environmental evaluation model (site capability evaluation) and giving privilege to ecological parameters so forest was divided to four main land uses: commercial forests, rehabilitated forests, protected forests and conserved forest. There is also a tourism land use (extensive and intensive out door recreation) which is compatible with forest land uses. Specific evaluation model is based on following models: Makhdoum ecological model, Bibby forest land capability classification model and FAO land evaluation model for forestry. It is necessary to mention hat Makhdoum model (with little changes and omitting the ineffective parameters) is used for tourism use determination. Effective ecological parameters on forest site capability were recognized and used as evaluation criteria in specific evaluation model this process was performed by using Lorey average height of trees which was applied as an index to show the difference between sites. Minor sample models were recognized to investigate the method for applying evaluation results in forest activities management. The research consequences is Kazemrood region shows: firstly altitude, slope, soil (type, depth, texture and drainage), climate are the effective ecological (physical) parameters on site capability. Secondly site capability evaluation by using specific evaluation model has presented better results while evaluation methods based on giving privilege (either applying weight of parameters or not) is not rejected and it com be provided to determine location of fields which are appropriate for a special kind management. Thirdly applying socioeconomic characters of environmental units is incompatible with one of the hypothesis of research which is related to sustainability and survival of forest ecosystems. Socioeconomic studies should be only used in the programming, used to solve the problem of livestock and human being in the north forests of Iran.
