基于GIS的县域土地利用景观格局演化研究——以大安市为例
GIS-based Study on the Evolution of County-scale Land Use Landscape Pattern
摘要
Abstract
Inorder to explore the intrinsic mechanism of regional land use change, Da'an City in west Jilin Province was taken as an example, on the basis of GIS and remote sensing interpretation data, relevant indexes of land use change and landscape ecology were selected to analyze the evolution of land use/land cover change and landscape pattern in the study area. The results showed that, in the recent decade, Da'an City has witnessed a decreasing mean patch area of farmland, grassland and woodland, and also aggravating fragmentation of woodland and grassland ; declining landscape diversity and increasing dominance degrees of certain landscapes; diversified land use types but lower rationality, increasing areas of certain landscape types.关键词
