摘要：研究土地利用转型及其生态环境响应对合理利用土地资源及实现生态环境的可持续发展有重要意义。本文选取徐州市铜山区年三个时期的TM遥感影像，利用ERDAS和ArcGIS图像处理软件对其解译获取土地利用转型变化数据，并建立土地利用转型和生态环境的定量联系。分析结果表明：1990-2010年间，铜山区建设用地的面积增幅最大，未利用地的面积减幅最大，耕地转向建设用地是最主要的地类转型。铜山区在1990、2000、2010年的生态环境质量指数分别为0.304、0.272、0.236，生态环境质量状况日趋严重且有继续恶化的趋向。影响生态环境好转或恶化的主导因素在1990-2000年、2000-2010年分别为林地与耕地之间的转化和耕地与建设用地之间的转化，建设用地的大幅增加使铜山区生态系统服务价值逐年减少。本文最后就改善生态环境质量也提出了一些建议。34679

Study on the Land Use Transformation and Its Eco-environmental Response in Tongshan
Abstract: It is important for the rational use of land resources and the sustainable development of the ecological environment to study the land use transformation and its eco-environmental response. We select the TM remote sensing images of Tongshan in three periods of 1990, 2000 and 2010 and use image processing software of ERDAS and ARCGIS to interpret the images for the land use transformation data. And establish the quantitative relationship of land use transformation and ecological environment. The analysis results show that: during the period of 1990-2010, the land areas of construction in Tongshan increased the most and the land areas of unused area reduced the most. And the transformation from cultivated land to construction land is the main land type transformation. The ecological environmental quality index of Tongshan in 1990, 2000 and 2010 is 0.304, 0.272, 0.236.The state of ecological environment is becoming more and more serious and has a tendency to continue to deteriorate. The dominant factors in the improvement of ecological environment or deterioration of ecological environment is the transformation between woodland and cultivated land in 1990-2000 and the transformation between cultivated land and construction land in 2000-2010.The ecological value of Tongshan decreases year by year because of the substantial increase in construction land. Finally, we also put forward some suggestions on the improvement of ecological environment quality.
Key words: land use transformation; eco-environmental response; Tongshan
