【摘要】：近年來,城市化的不斷推進使得生態(tài)系統(tǒng)面臨巨大壓力甚至誘發(fā)生態(tài)災難,而另一方面人類對于生態(tài)系統(tǒng)服務福祉的提升提出了新要求,因此經(jīng)濟發(fā)展和生態(tài)保護兩者之間的矛盾不斷激化。生態(tài)安全格局作為溝通生態(tài)系統(tǒng)服務和人類社會發(fā)展的橋梁,目前被視為區(qū)域生態(tài)安全保障和人類福祉提升的關鍵環(huán)節(jié)。在系統(tǒng)梳理生態(tài)安全格局與城市增長邊界、生態(tài)網(wǎng)絡、綠色基礎設施和生態(tài)控制線等概念內涵異同的基礎上,從熱點區(qū)域、生態(tài)源地指標篩選、生態(tài)阻力面設置與修正、相關研究成果應用等方面闡釋區(qū)域生態(tài)安全格局構建的近今研究進展,并指出當前研究的主要不足;同時提出了區(qū)域生態(tài)安全格局構建的重點方向,即生態(tài)安全格局構建的重要閾值設定、有效性評價、多尺度關聯(lián)和生態(tài)過程耦合等四個方面。
[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.
