摘　　要：以整个景观为研究对象,着重分析研究九寨沟的景观格局,景观之间的相互关系以及人类活动对景观的影响。从景观生态学的角度,结合遥感和地理信息系统技术,综合景观分类原理绘制出九寨沟景观分布矢量图,并建立景观空间数据库。运用景观生态学数量分析方法,选取斑块大小、斑块数、平均斑块面积、最大斑块指数、斑块形状指数、景观多样性、景观破碎化等景观指标,对九寨沟景区进行综合的、多层次的景观空间结构分析,从而对景区内景观格局变化的内在规律进行探讨,并针对景观破碎化现况,提出九寨沟生态旅游可持续性发展建议。Recent years, the landscape ecology have great application and development in home as a newly—developed disciplines of ecology. The landscape ecology mainly researchs the entire landscape, and focuse on studying analysis of landscape pattern, landscape interrelationship, and the impact of human activities on the landscape.This article from the view of landscape ecology, integrates landscape classification principles through remote sensing and GIS technologies to get the distribution of vector map Jiuzhaigou landscape. And establish landscape spatial databases. Landscape indicators are selected to integrate multi—level analysis of the structure of space Jiuzhaigou node landscape by using quantitative analysis method of landscape ecology to explore node landscape pattern change internal rules. And sustainability of development proposals are submitted for Jiuzhaigou ecotourism by the status of the landscape broken.
