| 摘 要： | 通过对贵州省退耕还林10个生态效益监测网络县设置的100个坡面固定样地,以及5个典型县16个坡面径流场各生态指标2年观测数据的分析,得出退耕还林后监测区各生态指标的改善情况如下:退耕还林后2年内土壤侵蚀模数和流失量减少78%,监测区植被覆盖率由12.4%增加到38.7%,平均综合生态效益指数已由0.18上升到0.53。

| Abstract: | By analyzing the 2-year observation data of ecologic index in 100 fixed sample sites in Guizhou under the "Grain-to-Green" ecological benefits surveillance network as well as 16 slope runoff sites in 5 typical counties, the paper primarily explores the delightful results: soil corrasion and loss deceases by 78%, vegetation coverage rate increases from 12.4% to 38.7% and the average ecological benefits index in the sample area rises from 0.18 to 0.53. |
