摘要

在GIS空间分析的基础上

借助领域专家知识归一化各侵蚀因子

对归一化的各侵蚀因子团进行叠加再分类和定量分析计算

为黄土高原地区水土流失监测网络布设的复杂空间决策过程提供辅助决策信息。在充分考虑黄土高原地区已有水土流失监测站、点的基础上

遵循国家有关水土流失监测站、点布设的相关规程规则

采用一级控制性监测点与二级局部监测点相结合的办法共布设监测站点138个。

Abstract

Based on the spatial analyses of GIS

the normalized factors are overlapped and reclassified using expert know ledge. Accordingly

quantitative computation is performed and the aided information is provided for the dec-ision of the monitoring netw ork layout of soil and water loss on the Loess Plateau in China. Af ter the existed mon-itoring stations are fully considered

138 new stations are laid by combining the first level control stations with second level local control stations under national regulations and specificat ions on the arrangement of monitoring stations of soil and water loss.
