    摘要:

    在GIS软件的支持下,通过对降水、土壤、地形、植被、人类活动等方面的资料进行收集和处理,分别生成R,K,SL,C,P等各个因子栅格格式的分布图,然后代入通用土壤流失方程(USLE)进行各因子间空间叠加运算,最终得出研究区水土流失强度分布图。对水土流失现状进行评价并对产生水土流失的原因进行分析,将研究区分为近郊地区、三川地区、南北沙河地区等3部分,最后分区域提出了水土流失的治理措施。

    Abstract:

    Data on precipitation,soil,terrain,vegetation and management activities in the groundwater supply district of Ji' nan City were collected and treated in a geog raphical information system(GIS)to produce distribution grid maps of R,K,SL,C and P.These attribute maps were overlain and computations were undertaken using USLE.The results were used to produce a soil and water loss intensity map.From this map the present status of soil and water loss in the district was determined and the reasons for these conditions were assessed.The study area was then classed into three separate categories, namely urban area,three-valley area, Shahe area and corresponding soil and water loss management measures were determined.
