摘要

区域水土流失的快速调查和评价对于水土保持宏观决策、灾情快速反应以及水土流失定期公告制的建立具有十分重要的意义。立足于区域水土流失问题的探索和 3S技术应用的研究

提出了区域水土流失宏观快速定量评价的方法及其实现的技术路线

并以整个黄土高原为研究区进行了实例研究

确定了一套适于该区水土流失宏观定量评价的指标

建立了相应的评价模型

并利用该模型对研究区一定年限内的水土流失状况进行了评价

获得了令人满意的结果。

Abstract

The rapid survey and assessment study on region-scaled soil and water loss is very sigificant macro-decision-making of regional soil loss control

quick control to natural disasters and construction poster-regime on soil loss regularly.Based and on the study of region-scaled soil loss and 3S application

the rapid assessing method is put forward and taking the whole loess plateau of China as a sample region

series of indices are defined; the model is set up to help to appraise the soil loss in this region; finally，soil loss of the loess plateau is assessed using the model

and some fine results have been got.
