以长株潭地区为例,利用Landsat TM、ETM+数据及其他辅助数据,运用生态经济学方法,评估了长株潭地区2000年、2010年两个年度的生态资产,分析了生态资产分布格局及其驱动因素。结果表明:1区域生态资产分布不均匀,株洲市最高,长沙市次之,湘潭市最低;2区域生态资产总体保持稳定并略有增加,但人均生态资产降幅较大,其中区域人均生态资产下降了7.93%、长沙市人均生态资产下降了11.20%、株洲市人均生态资产下降了5.39%、湘潭市下降了4.16%;3长株潭区域生态资产变化是自然环境因素和人类活动共同作用的结果,但人类活动是关键因素。基于以上研究结论,提出快速城市化的长株潭地区应走绿色、环保、低碳、集约、智慧的城市发展道路,实现人与自然的和谐发展。
Taking Chang-Zhu-Tan region as an example, this paper evaluates the ecological assets of Chang-Zhu-Tan region in 2000 and 2010 by using the method of ecological economics by using Landsat TM, ETM + data and other ancillary data, analyzes the distribution pattern of ecological assets and The driving factor. The results showed that: 1, the distribution of ecological assets in the area was uneven, the highest in Zhuzhou, the second in Changsha and the lowest in Xiangtan; the overall ecological assets in the two areas remained stable and slightly increased, but the decline in per capita ecological assets was larger, , 7.93% in Changsha, 11.20% in Changsha, 10.19% in Zhuzhou, 5.39% in Xiangzhou, and 4.16% in Xiangtan. 3 The changes of ecological assets in Changsha, Zhuzhou and Xiangtan are the result of the interaction between natural environment and human activities , But human activity is the key factor. Based on the above conclusions, Changsha-Zhuzhou-Xiangtan region, which proposes rapid urbanization, should follow the road of green development, environmental protection, low carbon, intensive and smart urban development to realize the harmonious development of man and nature.
