摘要

第一次全国水利普查水土保持情况普查包括水土流失、侵蚀沟道和水土保持措施等3种对象。水土流失普查

采取宏观遥感调查与地面系统抽样调查相结合的方式

利用土壤侵蚀模型评价不同侵蚀类型的分布、面积和强度。侵蚀沟道普查

利用遥感影像、DEM(数字高程模型)等基础数据得到侵蚀沟道位置

通过野外调查和空间分析

得到侵蚀沟道面积、数量与分布。水土保持措施普查

利用各种基础资料综合分析得到水土保持工程措施和植物措施的类型和数量。

Abstract

The objects of soil and water conservation in the first national census for water resources include soil loss

erosion channel

and soil and water conserv ation measures. The census for soil loss adopts the methods of combing macro remote sensing survey with ground system sampling survey and utilizing soil erosion evaluation models to evaluate the distribution

size

and intensity of different erosion types. Erosion channel census uses the elementary data from remote sensing and DEM to gain the location of erosion channel and obtains the area

number

and distribution by field survey and spatial analysis additionally. Through analyzing various basic data comprehensively

soil and water conservation measures census acquires the types and quantity of engineering measures and plant measures.
