【摘要】：分析区域社会经济发展与环境的生态效率关系,描述区域发展对生态环境资源消耗和占用状况,揭示导致生态变化的重要因素,有助于为区域可持续发展政策提出奠定基础.通过对陕西秦岭南麓区域发展与生态足迹影响因素的差异性分析以及区域内2005—2014年城市发展指数CDI和生态足迹EF的测算,分析陕南三市CDI、EF和生态效率的年际变化趋势及相互影响关系.研究表明:陕南三市CDI和人均EF均呈现不断增长态势,2005—2014年,汉中市、安康市、商洛市CDI分别增长34.99%、42.91%、33.39%;人均EF分别增长66.59%、73.59%、67.04%.结果显示,陕南三市生态效率呈现先升后降的趋势,环境效率年际变化波动较大.资源效率是导致陕南三市生态效率波动变化的主要因素,与生态效率的变化趋势基本一致.化石能源消耗和建设用地占用不断增长是导致资源效率降低的主要原因.陕西秦岭南麓区域社会经济发展能力逐步增强,但资源的高消耗和占用使生态环境压力持续增大,发展循环经济、开发生态旅游等成为政策着力点.
[Abstract]:This paper analyzes the relationship between regional social and economic development and the ecological efficiency of the environment, describes the consumption and occupation of eco-environmental resources by regional development, and reveals the important factors leading to ecological change, which is helpful to lay the foundation for the policy of regional sustainable development. Based on the analysis of the difference between regional development and ecological footprint in the southern foothills of Qinling Mountain, Shaanxi Province, and the estimation of the urban development index (CDI) and ecological footprint EF (EF) in the region from 2005 to 2014. The interannual trends of CDIEF and ecological efficiency in three cities of southern Shaanxi were analyzed. The study shows that the CDI and EF per capita in the three cities of southern Shaanxi are increasing continuously from 2005 to 2014, the CDI of Hanzhong, Ankang and Shangluo increased 34.9999 and 42.91, respectively, and the EF per capita increased by 73.59and 67.04respectively. The results showed that the ecological efficiency of the three cities increased first and then decreased, and the environmental efficiency fluctuated greatly. Resource efficiency is the main factor leading to the fluctuation of ecological efficiency in the three cities of southern Shaanxi, which is basically consistent with the change trend of ecological efficiency. The consumption of fossil energy and the increasing occupation of construction land are the main reasons leading to the decrease of resource efficiency. The capacity of regional social and economic development in the southern foot of Shaanxi Qinling Mountains has been gradually strengthened, but the high consumption and occupation of resources make the pressure of ecological environment continuously increase, and the development of circular economy and the development of ecotourism become the policy focus.
