摘要
基于GIS空间分析与数理统计方法、生态环境质量指数和生态贡献率方法对2005—2010年闽清县土地利用/覆被变化动态特征和土地利用变化引起的生态环境效应进行了定量分析.结果表明,(1)2005—2010年,闽清县土地利用/覆被变化主要表现为林地、水域的减少,耕地、草地、建设用地、未利用地增加的趋势.(2)2005—2010年闽清县的区域生态环境质量指数从0.718 8下降至0.715 7,局部呈现出一种下降的趋势.(3)局部地区生态环境呈负向发展,其中林地锐减对区域土地利用/覆被变化产生的影响最为深刻.
Based on GIS spatial analysis and mathematical statistics methods, the ecological environment quality index and ecological contribution rate of 2005-2010 Minqing county land use/cover change and land use change caused by the ecological and environmental effects are quantitatively analyzed. The results show that, （ 1 ） the area of forest and water decreased while the area of cropland, grassland, unused land and construction land increased in Minqing county from 2005 to 2010. （ 2 ） The regional eco-environmental quality index decreased from 0.718 8 in 2005 to 0.715 7 in 2010. The overall quality of regional eco-environment has maintained a declining trend. （ 3 ）It should also be noted that the local ecological environment presents a negative evolution, and the deforestation could be the most profound factor to influence the regional land use/cover change.
