典型示范区石漠化治理工程生态效益监测研究——以毕节撒拉溪、关岭花江示范区为例

Study on Ecological Benefit Monitoring of Rock Desertification Control Project in a Typical Demonstration Area——Take Bijie Salad Stream and Guanling Flower River

以毕节撒拉溪与关岭花江两个典型示范区石漠化治理工程为研究对象,分析了2010—2015年五年间两示范区石漠化治理工程生态效益监测的变化,研究了不同示范区石漠化治理工程生态效益监测的变化特征。并基于3S技术进行信息提取技术和人工遥感影像解译,同时根据研究方法确定选择以毕节示范区、花江示范区的土地利用、水土流失和石漠化动态变化作为监测因子,研究结果表明:不同示范区石漠化治理工程生态效益监测体现出不同特征,在实施石漠化治理工程后,示范区土地利用结构发生有效转变,水土流失得以减轻。各等级示范区石漠化发生变化明显,年变化率较高,同时石漠化面积减少,其等级得到一定程度减轻。

This paper,taking Bijie salaxi demonstration zone and Guanling Huajiang demonstration area of rocky desertification control project as the research object,analyzes the different demonstration area of rocky desertification control project of ecological benefit monitoring changes of the ecological benefits among the five years from 2010—2015,and the different characteristics demonstration area of desertification control project. And Based on information extraction technology,artificial remote sensing image interpretation and 3 S technology,choosing the Bijie demonstration zone according to the research method of land use in Huajiang demonstration area,soil erosion and desertification dynamic change as monitoring factors,the results showed that： ecological benefit monitoring of different treatment project demonstration area of rocky desertification showed different characteristics. After the implementation of desertification control,it change the land use structure demonstration area,soil erosion. From the research of rocky desertification monitoring and analysis can be seen through the rocky desertification control project,each kind of show The Rocky Desertification in the area is obviously changed,the annual rate of change is higher,the rocky desertification area is reduced,and the grade level is reduced.
