区域生态安全格局构建研究进展与展望
发布时间：2018-11-25 22:42
【摘要】：近年来,城市化的不断推进使得生态系统面临巨大压力甚至诱发生态灾难,而另一方面人类对于生态系统服务福祉的提升提出了新要求,因此经济发展和生态保护两者之间的矛盾不断激化。生态安全格局作为沟通生态系统服务和人类社会发展的桥梁,目前被视为区域生态安全保障和人类福祉提升的关键环节。在系统梳理生态安全格局与城市增长边界、生态网络、绿色基础设施和生态控制线等概念内涵异同的基础上,从热点区域、生态源地指标筛选、生态阻力面设置与修正、相关研究成果应用等方面阐释区域生态安全格局构建的近今研究进展,并指出当前研究的主要不足;同时提出了区域生态安全格局构建的重点方向,即生态安全格局构建的重要阈值设定、有效性评价、多尺度关联和生态过程耦合等四个方面。
[Abstract]:In recent years, with the continuous development of urbanization, the ecosystem is facing enormous pressure and even leading to ecological disaster. On the other hand, human beings have put forward new requirements for the improvement of ecosystem services. As a result, the contradiction between economic development and ecological protection continues to intensify. As a bridge between ecosystem services and the development of human society, the ecological security pattern is regarded as the key link of regional ecological security and the promotion of human welfare. On the basis of systematically combing the similarities and differences between ecological security pattern and urban growth boundary, ecological network, green infrastructure and ecological control line, the index selection of hot spot, ecological source area, setting and revising of ecological resistance surface are carried out. The research progress of the construction of regional ecological security pattern is explained in the application of related research results, and the main deficiencies of the current research are pointed out. At the same time, the paper puts forward the key direction of constructing the regional ecological security pattern, that is, the important threshold setting, the effectiveness evaluation, the multi-scale correlation and the ecological process coupling of the construction of the ecological security pattern.
