Abstract

Cities are gradually developed on the basis of adapting and transforming the natural environment. In a certain urban area, human activities, natural environment, and other factors and their mutual influence constitute the urban ecological environment. Therefore, the evaluation of urban ecological environment quality is of great significance to the analysis of urban development. This paper takes a city in Western China as the evaluation object, uses AHP to determine the index weight, reasonably analyzes the current situation of the urban ecological environment, and further comprehensively evaluates the quality of the urban ecological environment. The study shows that from 2013 to 2018, the comprehensive capacity of the city's ecological environment quality showed a steady upward trend, except that the natural disasters of floods and mudslides in 2014 had a certain degree of fluctuation. The comprehensive index of ecological environment quality has increased from 0.337 in 2013 to 0.412 in 2018. The overall level is still low, but the development speed is relatively stable. The urban ecological environment has been gradually improved, and society, economy, and nature have maintained a certain degree of sustainable development.

摘要

城市是在适应和改造自然环境的基础上逐步发展起来的。在一定的城市区域内,人类活动、自然环境等因素及其相互影响构成了城市生态环境。因此,评价城市生态环境质量对分析城市发展具有重要意义。本文以中国西部某城市为评价对象,采用层次分析法确定指标权重,合理分析城市生态环境现状,进一步综合评价城市生态环境质量。研究表明,2013 年至 2018 年,城市生态环境综合承载力呈稳步上升趋势,仅 2014 年洪水和泥石流等自然灾害出现一定波动。生态环境质量综合指数由 2013 年的 0.337 上升到 2018 年的 0.412。整体水平仍然较低,但发展速度相对稳定。城市生态环境得到了逐步改善,社会、经济和自然保持了一定程度的可持续发展。
