苏州市1985~2010年 LUCC 及生态连通性时空差异研究
Study on Spatial-temporal Di fferentiation in LUCC and Ecological Connectivity from 1985 to 2010 in Suzhou
摘要
Abstract
According to 2-term ( the year 1985 and 2010) remote sensing images of Suzhou city, the author analyzed the spa-tial-temporal differentiation in Land Use Cover/Land Use Change ( LUCC) and ecological connectivity in this city, and studied the relationship between LUCC and ecological connectivity.It was found that:from 1985 to 2010, the LUCC in Suzhou city changed in-tensively;among different land-use types, the area of cultivated land reduced most, and the area of urban and rural residence changed most extensively and most sharply.Impacted by the LUCC, the ecological connectivity of Suzhou changed obviously, and the ecological obstruction in 84.2%of land region of this city showed a rising trend, due to the rapid expansion of construction land area;while that in only 15.8%of land region decreased, and the ecological connectivity increased, because of the transformation of other land-use types to water area and grassland.The area of ecological islet in Suzhou was increased by 15.84%.Through effective land consolidation, transforming the rural residence to more ecological farmland, water area, grassland or wood land is an important approach to reduce the ecological obstruction, enhance the ecological connectivity, and effectively improve the ecological environ-ment of Suzhou city.关键词
