Dynamic Analysis of Landscape Changes in the Heihe River Basin Using Remote Sensing and GIS1

摘要

Landscape spatial pattern is one of the main study fields in landscape ecology, as well in land use and land cover change studies. The formation and variation of landscape pattern are considered as the composite reactions of the area ecological environment quality, which come from mufti-factors interaction of nature and man-made. Heihe River Basin is the second largest endorheic drainage in the northwest of China; it is the typical arid inland river basin with desertscape. This paper is aimed to intensively study the drive mechanism of landscape pattern changes, and then provides a reference for the environmental protection and construction of Heihe region.
