基于GIS的西洞庭湖区森林景观空间格局综合评价

以地理信息系统为技术手段，获取西洞庭湖区森林景观类型基本信息。建立景观类型属性数据库，对森林景观空间格局特征进行分析；在此基础上，运用主成分分析法进行景观空间格局综合评价。结果表明：森林景观空间格局综合水平较高的为桃源县、澧县、鼎城区、临澧县、汉寿县，其中最高的为桃源县；综合水平居中的有和洑林场、常德林场、津市市、安乡县、柳叶湖旅游度假区；西洞庭农场、武陵区、涔澹林场、贺家山原种场、西湖农场综合水平较低，其中西湖农场综合水平最低。该方法为西洞庭湖区森林生态系统的景观格局优化、森林资源合理利用与管理提供依据。

Integrated Evaluation of the Forest Landscape Patterns in West Dongting Lake Region Based on GIS

The attribute database of forest landscape types is established and forest landscape patterns are analyzed in the West Dongting Lake area by means of geographic information system technology. Based on these, landscape patterns are evaluated by using Principal Component Analysis method. The results show that： the higher level of the forest landscape patterns is in Taoyuan County, Li County, Dingcheng District, Linli County, Hanshou County, among which, the highest is in Taoyuan County; the middle level of the forest landscape patterns is in Hefu Forest Farm, Changde Forest Farm, Jinshi County, Anxiang County, Liuyehu Tourist Resort; Xidongting Farm, Wuling District, Cendan Forest Farm, Hejiashan Farm is the lower, and Xidongting Farm is the lowest. Integrated evaluation of the Forest Landscape Patterns is a way which provides the basis for landscape patterns optimization of the forest ecosystems, rational use and design and management of forest resources in West Dongting Lake Region.
