基于遥感和GIS的天津滨海新区30年间生态用地变化分析
Analysis of 302Year Ecological Land Use Variation in the Binhai New District of Tianjin Based on Remote Sensing and GIS
摘要
Abstract
Based on the remote sensing TM images in 1979 and 2004 and the SPOT image in 2009 in the Binhai New Dist rict of Tianjin the variations of land use and land cover in this area w ere determined by the visual interpret ation method and spatial o2 verlay function in GIS. Moreover, the overall characteristics of the ecological land use, and the interactions between ecological land use and non2ecological land use and between different ecological land uses w ere investigated, and the driving factors for these interact ions w ere also analyzed. The results show ed that the area of tot al ecological land use decreased from 1979 to 2009, and about 56 424. 74 hm2 and 8 874. 35 hm2 of ecological land uses w ere converted into the farmland and construction land uses around 2004. In t erms of ecological land use, the ratios of forest and urban green land were low , and the wet land w ith high eco2 logical service function was converted into saline land, w hereas the part of sea area w as converted int o w etland. T he main driving factors for the above conversions of ecological land uses w included the natural factor, urban expansion, and economic factors.关键词
