| 摘 要： | 根据1999～2008年数据分析重庆市的土地利用变化情况,并在此基础上研究其与区域社会经济发展和生态环境效应的相关性.结果表明：①1999～2008年间重庆市耕地急剧下降,其面积净减293 679.7 hm2,建设用地大幅增加,其面积净增74 334.1 hm2.②重庆区域建设用地变化对经济发展的弹性系数较大,GDP、固定资产投资总额、工业增加值与建设用地面积变化呈正相关,与耕地面积变化呈负相关,表明重庆经济社会发展主要依赖于土地资源的开发.③重庆市1999年的ESV为849.80亿元,2008年为901.44亿元,平均增幅为0.7％,总体变化不大,虽然重庆市的生态服务价值呈上升趋势,但总体价值仍不高.

On the basis of this, the correlation with regional socio-economic development and eco-environment was studied. The results showed that during 1999 -2008 Chongqing sharp decline in arable land, the area net decrease in 293 679.7 hm2, significant increase of construction land, the area net increase＇74 334.1 hm2. GDP, total fixed asset investment, industrial added value and the construction area was positively correlated, and arable land change was a negative correla- tion. It indicated that the economic and social development of Chongqing mainly depends on the development of land resources. In addition, re- turning land for farming to forestry, construction of the wetland ecosystem, making the Chongqing municipality, although the value of ecosystem services is rising, but the overall value is still lower. |
