青藏高原东南部线性工程对区域植被的影响研究

STUDY ON THE INFLUENCE OF LINEAR ENGINEERING ON REGIONAL VEGETATION IN SOUTHEAST TIBET PLATEAU

青藏高原东南部工程项目种类多,大面积的占地会对项目一定范围内的植被造成不同程度的破坏,本文以川藏线雅安至昌都沿线植被情况为例,通过现场资料以及遥感解译等手段对研究范围内的植被情况进行初步调研,得到了沿线植被种类以及分布情况,进一步的评价了植被的损伤情况。研究结果表明雅安至昌都段工程对植被的破坏性造成了一定程度的水土流失,打破了当地生态系统的平衡。

There are many types of engineering projects along the Sichuan-Tibet line,and large areas of land will cause varying degrees of damage to the vegetation within a certain area of the project.This article takes the vegetation along the Sichuan-Tibet line from Ya’an to Chamdo as an example,using field data and remote sensing interpretation Preliminary investigations were conducted on the vegetation within the research area by means of other means,and the types and distribution of vegetation along the line were obtained,and the damage of the vegetation was further evaluated.The research results show that the destructiveness of the Ya’an Qamdo project to vegetation caused a certain degree of soil erosion and broke the balance of the local ecosystem.
