文摘内容 With land use landscape pattern of Da’an City in west Jilin Province as an example, internal mechanism of regional land use changes was explored on the basis of GIS and remote sensing interpretation data. County-scale RS images were processed in ENVI, relevant indexes of land use change and landscape ecology selected to analyze quantity structure change, dynamic change and transition matrix of land use, and evolution trends of land use/cover change and landscape pattern in the study area analyzed. The results showed that from 1995 to 2005 Da’an City has witnessed a decreasing mean patch area of farmland, grassland and woodland, 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.
