澜沧江(西藏段)流域植被保护与水能资源开发关系的研究

Study on Vegetation Protection and Hydropower Resources Development of Lancang River Basin in Tibet

澜沧江(西藏段)流域水能资源丰富,但开发水能资源的过程会破坏流域植被,因此为协调好流域植被保护与水能资源开发的关系,开展项目研究。研究首先通过现场调查、遥感解译等方法获取研究区植被类型分布,利用研究区DEM提取海拔分异,再通过GIS叠加分析,得出研究区段植被类型分布最为丰富的结论,最后提出流域水能资源开发过程中应加强对3 900~4 300 m高程海拔区域植被的保护,并且重点优化此段海拔高程中水能资源利用开发方式的建议。

There are abundant hydropower resources in Lancang River basin in Tibet where vegetations are to be destroyedalong with the development of hydropower resources. So the study purpose is to coordinate the relationship between vegetationprotection and hydropower resources development. Firstly the distribution of vegetation type is understood in the study areaby field survey and remote sensing interpretation methods. It is concluded that there are abundant vegetations distributing inthe study area by using altitudinal differentiation extracted with DEM and GIS overlay analysis. Therefore it is proposed thatthe protection of vegetations in the elevation area of 3900-4300m shall be strengthened during the development of hydropowerresources and the development and utilization mode of hydropower resources in the above elevation area shall be emphaticallyoptimized.
