| 摘 要： | 生态建设的主要目的是提高区域的生态承载力以促进可持续发展,但目前对生态建设效益的评价多为生态建设工程在经济、社会、生态上的影响效益评价,很少对生态建设前后的生态承载力变化进行评价,因而目前的生态建设效益评价对生态建设最终目的的达成效果衡量缺乏借鉴。本研究对退田还湖生态工程建设在提高区域生态承载力方面的效益进行了评价,并将生态承载力理论引入洪涝灾害频发地区,构建了在洪涝灾害风险下的生态承载力评价体系,拓宽了生态承载力理论的应用范围。最后在评价退田还湖对洞庭湖区生态承载力影响的基础上,提出该区今后可持续发展中的关键问题是寻求有效的替代产业,增强经济能力,以更高的生产力来获得更大的资源承载力。

| Abstract: | Ecological construction for regional sustainable development is mainly by increasing ecological carrying capacity.However,most ecological evaluation studies today focus on economic,social and ecological aspects,very much lacking on the carrying capacity of ecosystems.Such is a hindrance to efforts in weighing results of ecological construction.This paper evaluates the effects of "re-submerging polder" policy on the ecological carrying capacity of Dongting Lake.Introducing ecological carrying capacity theory to a flood prone region is the basis of the evaluation.Thus the paper broadens the scope of application of ecological carrying capacity theory.Finally,the paper suggests important points for sustainable development in the Dongting Lake area. |
