摘要

在前人工作的基础上

该文提出了评价黄土高原生态环境脆弱性的数学方法

并对黄土高原105个水土流失重点县进行了脆弱度指标计算。以脆弱度指标为依据

对黄土高原105个县生态脆弱性进行了分区

按其脆弱状况

划分为强脆弱区;中脆弱区;轻脆弱区3个区。因而为黄土高原生态环境评价提供了一种新的方法

也为黄土高原综合治理提供了依据。

Abstract

A mathematical method of judging ecological fragility in loess plateau region is given

and the fragility indexes at 105 counties are calculated.Three types of eco-environmental fragility at those major erosion countries

i.e.intense fragility region

intermediate fragility region

slight fragility region

are divided on their fragility indexes.Thus

a new basis for comprehensive control in loess plateau region is provided.
