摘　　要：目前生态资产评估的定量评估已成为生态学和环境经济学领域的研究热点和重点。生态资产定量评估将生态资产的价值赋予货币的表现形式,可以加强对当地生态资源的保护,促进区域生态系统服务功能的发挥。对城市地区进行生态资产价值评估,可以明确城市地区的生态保护价值,为城市生态功能定位以及生态文明建设提供科学依据。以云南省昆明市作为研究对象,依据所查阅资料,构建了包含直接价值和间接价值的生态资产价值评估体-系。研究结果表明:2018年昆明市生态资产价值总量为2020.44亿元,单位面积生态资产价值为940.92万元·km^(-2),结果表明昆明市生态资产价值对当地发展影响深远。该结果为我国城市生态资产评估体系的完善提供了参考,同时也为相关政策的制定和城市可持续发展提供定量分析基础和决策支持。Nowadays,the quantitative assessment of the ecological assets assessment is a hot topic and focus in the field of ecology and environmental economics.Quantitative evaluation of ecological assets can monetize the value of ecological assets,strengthen local ecological environment protection,and promote the service functions of regional ecosystems.Taking urban area as research area can clarify the value of local ecological protection and provide a scientific basis for the positioning of the functions and the construction of ecological civilization.Based on the information reviewed,this paper used Kunming as the research object,and build an ecological asset value evaluation system,including direct value and indirect value.The results showed that the total ecological assets value of Kunming in 2018 was 202.044 billion yuan,and the unit area value was 9.4092 million yuan·km^(–2).The direct value and indirect value on average accounted for 23.30%and 76.70%of the total value,respectively.The results provide a reference for the construction of the urban ecological assets evaluation system,and also provide a quantitative analysis basis and decision support for the formulation of policies and sustainable urban development.
