Title: Landscape Types and Characteristics of the in the Upper Reaches of the Yalong River
Abstract: In this paper,based on the translated data from remote sensing images(ETM+) in 2002 and the field survey,researches were conducted on the landscape types and characteristics of the upper reaches of the Yalong River.The results have shown that(1)The landscape type in this area was mainly made up of artificial and natural landscape ecological systems,the former had a better stability than the latter.(2)Its landscape ecological system diversity displayed that arbor species in forest communities were single,but the species of shrub and grass were abundant.(3)The Characteristics of quantative attribute of patches were as follows:the rate of woodland,grassland,cultivated field,streams,constructionland,unutilized land was 19.89%、66.50%、0.82%、0.37%、0.03% and 12.40%,respectively.Grassland was the stroma,whose influence on the whole landscape was the most,while woodland seemed to be scattered and fragmentized.(4)The diversity indices of landscape type area,perimeter and pathches were respecitively 0.9137,1.0224 and 1.2556,which showed that the distribution of landscape type area was the most uneven,and on the contrary,the distribution of the patches was the most well-proportioned among them.
