摘要
根据铜山县1997-2007年的土地利用覆被变化数据,运用Costanza生态服务价值计算公式得到全县1997-2007年的生态服务价值,再结合铜山县1997-2007的GDP变化情况,得出铜山县1997-2007生态经济协调度的动态变化情况。然后计算铜山县不同乡(镇)1997-2007年的生态经济协调,并结合铜山县的实际情况对其变化做出解释。通过研究发现、铜山县的从1997-2007年生态经济协调度呈现先降后升的"U"型变化,从1998、2002、2007年的生态经济协调度来看,铜山县自然资源丰富的东北片生态经济协调度整体上要低于西北片、东南片的平原地带。
The ecological service value from 1997 to 2007 in Tongshan County are calculated by using Costanza formula and land use/land cover changes data, and the dynamic changes of eco-economic harmony from 1997 to 2007 in Tongshan are get through by combining the GDP changes. Then the paper analyzes the eco-economic harmony of Tongshan County and its different townships from 1998 to 2007, and explains changes based on actual situation of Tongshan County. It is found that the eco-economic harmony from 1997 to 2007 initially decreases and then increases in a ＂U＂-shape. According to the eco-economic harmony in 1998, 2002 and 2007, the eco-economic harmony of northeast Tongshan County that is rich in natural resources is inferior to flat-bottomedland in the northwest, southeast.
