【摘要】 城市绿地作为城市复合生态系统的重要组成部分,拥有巨大的生态系统服务价值,对改善城市环境、促进人体健康、维持生态稳定具有重要作用。以南京市为例,在统计该市绿地面积的基础上,根据生态经济学原理和方法,对该市2006—2015各年度的城市绿地生态系统服务价值进行了估算,并采用全排列多边形图示法对该市绿地生态系统服务功能进行评价。结果表明:(1)就南京市绿地系统的生态服务总价值而言,2006—2015年该市绿地系统的生态服务总价值总体呈上升趋势,由2006年的125.2144亿元上涨到2015年的164.3537亿元,净增加了约39.1392亿元,表明该市绿地系统的生态服务价值巨大,且随时间的推移不断增值。(2)就南京市绿地系统的生态服务价值构成而言,该市绿地系统各项生态服务价值历年均值由大到小依次为:降温(调节气温)>涵养水源>释氧>固碳>减噪>滞尘>吸收氮氧化物>吸收二氧化硫。(3)就南京市绿地系统的生态服务功能而言,该市绿地系统的生态服务功能由弱变强,不断改善。通过本文研究,可为该市绿地系统的科学规划提供理论依据。更多还原

【Abstract】 Urban green space plays an important role in urban compound ecological system, having great value of ecosystem services, beneficial to improving the urban environment, promoting human health and maintaining ecological stability. Based on the statistics of the city green space area, this paper taking Nanjing as an example, estimated the value of ecosystem services of urban green space from 2006 to 2015 according to the principle and the methods of ecological economics, and used the method of entire-array-polygon diagram to evaluate the function of the ecosystem services of urban green space. The results show that:（1） In terms of the total ecological service value of Nanjing green space, from 2006 to 2015, the total ecological service value of Nanjing green space was on the rise in general, rising from 12.52144 billion yuan（2006） to 16.43537 billion yuan（2015）, and net value increased about 3.91392 billion yuan, showing that the ecological service value of Nanjing green space was very high and on the rise over time.（2） In terms of the composition of ecological service value of Nanjing green space, average of various ecological service values were arranged as cooling（temperature reduction）>water conservation>oxygen releasing>carbon sequestration>noise reduction>dust detention> Nox absorption>SO₂ absorption.（3） In terms of the function of ecological service of Nanjing green space, the function of ecological service of Nanjing green space experienced the changing process from weak to strong, and the function gradually got better. Through this study, we can provide the theoretical basis for the scientific planning of the city green space system.更多还原
