摘要

在传统水土流失分区研究基础上

探索应用GIS技术对现有地图和卫星影像解译分析

提取影响水土流失主要因子的基础信息

建立图形和空间属性数据库。利用1:5万GRID数据提取研究区的水土流失地学模型

利用ArcGIS强大的空间分析功能

对重庆市进行了水土保持监测区的划分。针对不同监测分区特点

提出了重庆市水土保持监测站点总体布局方案

为今后监测站网建设提供了理论依据。

Abstract

Based on the traditional regional studies of soil erosion

the paper explored using GIS technology to analysis the existing maps and satellite imagery

to extracte the basic information of main factors affectting on soil erosion

and established a database of graphics and space property. The 1，5 000 GRID was used to extract data of soil erosion model and subdivide the monitoring area of soil and water conservation with the powerful ArcGIS spatial analysis function. The paper put forward the general layout scheme of Chongqing soil and water conservation monitoring sites base on different monitoring subdivision characteristics

which may provide some theoretical basis for the construction of monitoring networks in the future.
