【摘要】：河西走廊嚴峻的生態(tài)形勢、不容忽視的生態(tài)功能和獨特的地理位置,決定了河西走廊在國家生態(tài)環(huán)境建設布局中的重要地位。研究河西走廊的生態(tài)環(huán)境問題,構建河西走廊的生態(tài)環(huán)境評價體系,有利于國家和甘肅省環(huán)境保護當局發(fā)現河西走廊生態(tài)環(huán)境的現狀和發(fā)展趨勢,可以為西北荒漠化問題的治理和河西走廊生態(tài)環(huán)境的改善提出相應的政策指引。本論文以河西走廊5個市為研究對象,基于生態(tài)可持續(xù)發(fā)展、生態(tài)經濟學等基本理論,運用層次分析法、生態(tài)足跡模型和PSR模型等研究方法,從河西走廊的生態(tài)環(huán)境特點和現狀出發(fā),構建河西走廊生態(tài)環(huán)境綜合評價指標體系。具體而言,本研究從主要成因和結果表現兩方面,構建生態(tài)脆弱性評價指標體系；從人類對自然資本的供給和需求兩方面,構建生態(tài)可持續(xù)性評價指標;從壓力、響應、狀態(tài)三個方面,構建生態(tài)安全性評價指標體系。最后,在構建評價指標體系的基礎上,本文計算了河西走廊生態(tài)脆弱度、生態(tài)足跡和生態(tài)安全度,并據此提出治理對策和意見。研究結果顯示,河西走廊的生態(tài)脆弱度范圍、生態(tài)足跡值和生態(tài)安全度分別為0.4295-0.6262、-1.1765和0.4439,河西走廊的生態(tài)環(huán)境處于中度脆弱以上、生態(tài)赤字和不安全的狀態(tài)。
[Abstract]:The serious ecological situation, ecological function and unique geographical position of Hexi Corridor determine the important position of Hexi Corridor in the layout of national ecological environment construction. Studying the ecological environment of Hexi Corridor and constructing the ecological environment evaluation system of Hexi Corridor is beneficial to the national and Gansu environmental protection authorities to discover the present situation and development trend of the ecological environment of Hexi Corridor. It can provide corresponding policy guidance for the control of desertification in Northwest China and the improvement of ecological environment in Hexi Corridor. This paper takes five cities in Hexi Corridor as the research object, based on the basic theories of ecological sustainable development, ecological economics and so on, using analytic hierarchy process (AHP), ecological footprint model and PSR model, etc. Based on the characteristics and present situation of ecological environment in Hexi Corridor, a comprehensive evaluation index system of ecological environment in Hexi Corridor was established. Specifically, this study constructs the evaluation index system of ecological vulnerability from two aspects: the main cause of formation and the performance of the results. From two aspects of supply and demand of natural capital, ecological sustainability evaluation index is constructed, and ecological security evaluation index system is constructed from three aspects: pressure, response and state. Finally, on the basis of constructing the evaluation index system, this paper calculates the ecological fragility, ecological footprint and ecological security degree of Hexi Corridor, and puts forward some countermeasures and suggestions on this basis. The results show that the range of ecological fragility, ecological footprint and ecological security of Hexi Corridor are 0.4295 ~ 0.6262, 1.1765 and 0.4439, respectively. The ecological environment of Hexi Corridor is above moderate fragility. Ecological deficits and insecurity.
