松嫩平原土地利用/覆被变化及其驱动因素分析
nalysis on Land Use and Land Cover Change and its Driving Forces in the Songnen plain
本研究以松嫩平原1980年、1995年、2000年和2010年4期遥感影像为基础数据,辅以松嫩平原1:10万地形图、松嫩平原1:25万矢量县界数据。在GIS空间数据平台的支持下,采用空间分析和统计方法,对松嫩平原近30年来土地利用/覆被变化情况进行分析研究。结果表明:1980-2010年,30年间松嫩平原土地利用总的状况发生了明显的变化,主要体现在"三增四减",即耕地(水田和旱田)、城镇用地、未利用地增长,而草地、林地、湿地和水域减少。耕地和盐碱地的大面积增加与湿地、草地及水域的大面积减少形成强烈对比。盐碱地的迅速增加和湿地、水域的大面积萎缩反映出区域城镇化进程加快和生态环境恶化的趋势。
he remote sensing images of 1980、1995、2000、2010 were chosen as the data,with the Songnen Plains 1:100000 topographic map and 1:250000 vector county line data. Based on GIS spatial data, using the spatial analysis and statistics methods, LUCC of Songnen Plain nearly 30 years was analyzed and researched. The result indicated that, between 1980 to 2010 years, LUCC changed notably between 30 years, and mainly reflected in three add and four minus. The area of cultivated land (paddy fields and dry farmland), urban land and unused was growth. On contrast, the area of grass, forest land and wetland was reduced. The rapid increase in saline-alkali land and wetland, the waters of the large area atrophy reflected regional urbanization process and deterioration trend of ecological environment.
