【摘要】：城市生态系统健康评价适应于城市可持续发展和人类健康的需要。城市生态系统的健康是人类生存和发展的必要条件。维持城市生态系统健康,促进城市生态系统的良性循环,是国内外关注的重要课题。本研究探索昆明城市生态系统健康评价体系构建及其实践应用,旨在为昆明生态城市建设与城市规划等实际工作进行更加科学、客观的评判。构建一套城市生态系统健康评价体系,并对昆明城市生态系统健康状况进行综合评价,考察昆明城市生态系统发展的态势,识别影响昆明城市生态系统健康的不利因素,制定合理的管理措施,对促进昆明生态城市建设、协调人类与生态环境的关系、实现城市生态系统的可持续发展具有重要意义。本研究通过对国内外有关城市生态系统健康评价研究现状的评述,明确了城市生态系统的概念、结构、功能,对比分析了国内外采用的城市生态系统健康评价方法,本研究确定采用最广泛应用于城市生态系统健康评价研究中的活力(V)、组织结构(O)、恢复力(R)、生态系统服务功能(S)和人群健康(P)五个要素组成的评价体系对昆明城市生态系统健康评价进行研究,基于VORSP理论框架,应用模糊综合评价数学模型,采用主观的平均分配法确定总系统中5个不同要素的权重,选用客观的权重确定方法—变异系数法确定具体指标权重,具有一定的创新性。最终,本研究共选取28个指标,建立了昆明城市生态系统健康评价指标体系。依据国内外相关标准,对昆明城市生态系统健康评价标准共划分了五个等级,并根据隶属函数和模糊综合数学评价模型,对2002年至2013年共12年的昆明城市生态系统健康状况进行了评价,分析了昆明城市生态系统健康变化的原因,提出了相应的对策与措施,并对今后的研究内容给予相关的建议,以期为昆明城市未来的生态健康发展提供一定的参考思路。
[Abstract]:Urban ecosystem health assessment meets the needs of urban sustainable development and human health. The health of urban ecosystem is a necessary condition for human survival and development. Maintaining the health of urban ecosystem and promoting the virtuous circle of urban ecosystem is an important topic of concern at home and abroad. This study explores the construction of urban ecosystem health assessment system and its practical application in Kunming, in order to make a more scientific and objective evaluation for the practical work of urban ecological city construction and urban planning in Kunming. A set of urban ecosystem health evaluation system was established, and the comprehensive evaluation of Kunming urban ecosystem health status was carried out, the development situation of Kunming urban ecosystem was investigated, and the unfavorable factors affecting Kunming urban ecosystem health were identified. It is of great significance to establish reasonable management measures to promote the construction of ecological city in Kunming, to coordinate the relationship between human beings and ecological environment and to realize the sustainable development of urban ecosystem. In this study, the concept, structure and function of urban ecosystem health assessment are clarified by reviewing the current research situation of urban ecosystem health assessment at home and abroad, and the methods of urban ecosystem health assessment adopted at home and abroad are compared and analyzed. This study determined to use the most widely used in urban ecosystem health assessment of the five elements of vitality, organizational structure, resilience, ecosystem service function and population health assessment system to Kunming City Ecosystem health assessment, Based on the framework of VORSP theory, fuzzy comprehensive evaluation mathematical model is used to determine the weight of five different elements in the total system by using the subjective average distribution method, and the objective weight determination method-variation coefficient method is used to determine the specific index weight. Have certain innovation. Finally, 28 indexes were selected and the evaluation index system of urban ecosystem health in Kunming was established. According to the relevant standards at home and abroad, this paper divides the urban ecosystem health assessment standards of Kunming into five grades, and according to the membership function and fuzzy comprehensive mathematical evaluation model, This paper evaluates the state of urban ecosystem health in Kunming from 2002 to 2013, analyzes the reasons for the change of urban ecosystem health in Kunming, puts forward the corresponding countermeasures and measures, and gives some suggestions for the future research. In order to provide certain reference ideas for the future ecological healthy development of Kunming city.
