摘要
通过对玛纳斯流域的水土流失现状进行分析,利用三期遥感影像数据和温湿度等数据,对玛纳斯流域的土地利用、植被覆盖的水土流失风险进行评价,计算出生态指数RSEI,可以较为明显地观测流域的生态环境变化情况,并提出针对玛纳斯流域的水土流失治理对策,以期为区域的水土保持工作提供科学依据。
Based on the analysis of the current situation of water and soil loss in Manas basin,the risk of water and soil loss of land use and vegetation cover in Manas basin is evaluated by using the three-phase remote sensing image data and temperature and humidity data,and the ecological index rsei is calculated,which can be used to observe the change of ecological environment in Manas basin.Finally,the countermeasures of soil erosion control in Manas basin are put forward.It plays a certain scientific support for regional soil and water conservation.
