| Abstract: | Research on landscape pattern and ecosystem service changes is helpful for regional planning and management.Based on landuse data of 1990 and 2000,through ArcGIS and Fragstats software,combing cover landscape pattern indicts,ecosystem services changes landuse coverage and landscape pattern indices(diversity,evenness,connectivity and fragment indices),we analyzed the landscape pattern and ecosystem services changes.The results showed that(1)forestland,grassland and farmland are the main landscape patterns.Fr... |
