摘要

根据建立的水土流失治理率评价指标体系框架,对所选典型区域从水土流失治理角度进行健康综合评价。研究表明,永顺县吊井岩、新邵县寺门前和赣县白鹭圩水土流失治理率健康诊断指数在0.60~0.70之间,处于相对稳定阶段;万州区土地土旁和成县黄陈健康诊断指数在0.50~0.60之间,处于脆弱阶段;元谋县金雷、黔西县牛场拔和广安区璧山庙健康诊断指数小于0.50,处于恶性循环阶段。

Abstract

According to the evaluation indexes system frame established on improvement rate of soil and water loss, health diagnoses of several typical regions from soil and water loss improvement are comprehensively evaluated. The results show as follows: The health diagnosis indexes of improvement rate of soil and water loss in Diaojingyan of Yongshun county, Shimenqian of Xinshao county and Bailuyu of Ganxian county are from 0.60 to 0.70, which are in relative steady stage. Those indexes in Tudibang of Wanzhou county and Huangchen of Chenxian county are 0.50-0.60, which are in fragile stage. And the indexes in Jinlei of Yuanmou county, Niuchangba of Qianxi county and Bishanmiao of Guangan county are less than 0.50, which are in malignant circle stage.
