    摘要:

    水源涵养是生态系统为人类提供的重要服务功能之一。选取植被结构类型、植被郁闭度、地表层覆盖状况和土壤理化性质等指标,并将其量化,用ArcView软件分别作出了各指标矢量图。运用层次分析法,根据专家系统意见,构建判断矩阵,确定了各指标的权重。综合叠加各指标矢量图,得到了河北省水源涵养生态功能保护区分级图。研究认为,水源涵养生态功能保护区范围为河北省各大城市水源区、冀北、燕山山地和太行山山地等。

    Abstract:

    Water conservation in an ecosystem is one of the important service functions with which the ecosystem provides human being.Vegetation structure type,vegetation overlay degree,the earth surface cover condition,and soil physical and chemical properties were selected and quantified scientifically.Various digital maps were made separately by using ArcView software.By using AHP method and referring to the results from the expert system,a judgment matrix was constructed,various indicator weights were determined,and digital maps of various indicators were superimposed synthetically.The classification map of protected ecological function area for water conservation in Hebei Province was obtained.The protected ecological function area covers the water source areas of big cities in the province and the regions such as North Hebei Province,Mt.Yan,and Mt.Taihang.
