Abstract: In city, Greenbelt landscape is the basis of ecological system, the matrix and environment for people to live on and the carrier of biological diversity .Luoyang is taken as investigative object in this paper, using remote sensing to obtain greenbelt landscape information, and the greenbelt information special database was built. Under the direction of landscape ecology, the greenbelt landscape pattern is analyzed from such aspects as greenbelt quantity,greenbelt size, joint degree and spatial structure, etc.Applying primary component analysis to the vegetation landscape ecological comprehensive assessment,the landscape ecological comprehensive assessment of greenbelt is carried on in different districts.The assessing indices are divided into three types that the first is landscape pattern index, the second is separation index and the third is corridor density index. Because the greenbelt area of per man, the green cover ratio, the mean patch area, the landscape dominance and the diversity is maximum in Jianxi district. The result showed that:Jianxi is best,the second is Xigong , the third is Laocheng ,the fourth is Luolong, and Chanhe is worst.The method offers useful reference for regional landscape pattern assessment and puts forward the basis for optimizing the landscape structure of Luoyang greenbelt system.
