| 摘 要： | 在前人工作的基础上，该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。

| 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. |
