Abstract

Abstract:

Starting from the connotation of ecological environment evaluation,and according to the characteristics of natural ecological environment of Tibet Plateau ecological shelter zone,this paper discusses the methods of ecotope comprehensive evaluation for Tibet Plateau ecological shelter zone,which include evaluation index system establishment and index weight determination,evaluation unit selection,evaluation mathematical model research,etc.Then,the ecological environment quality of Tibet Plateau ecological shelter zone is evaluated objectively by using the general survey results of first national geographic conditions and various thematic data.Finally,the evaluation results are analyzed,and some ecological environment problems of Tibet Plateau ecological shelter zone and its protection are pointed out.

Key words: Tibet Plateau, ecological shelter zone, ecotope, comprehensive evaluation, principal component analysis
