摘要
以遥感影像作为基本信息源 ,在GLS的支持下 ,建立空间信息库 ,采用景观生态学研究方法 ,选取斑块大小、分维数、景观破碎度和景观优势度、均匀性、多样性指数等指标 ,对大伙房上游地区景观格局进行了分析。结果显示 ,研究区内景观空间格局基本构型以森林为主的景观结构 。
The upper reach of Dahuofang is an imporeant water resource and special conservung function area.By using renote sensing data as basic information resource and with suppore of GIS, a spatial information storehouse is built up.Through selecting patches,fractal dimension,shape coefficient,dominance and fragmentation index,equivalence, diversity index, etc,the landscape pattern in this region is analyzed. The result shows that the landscape pattem is mainly the forest,and that the function of the ecology system is in good situation.
