图们江地区城市绿地生态系统服务价值估算与评价研究--以延吉市为例

Estimation and evaluation of ecosystem service value of urban green space value in the Tumen River area:Acase study in Yanji City

城市绿地作为城市复合生态系统的重要组成部分,对城市可持续发展具有重要作用。该文以图们江地区的核心城市—延吉市为研究对象,利用2007—2018年统计数据,选取涵养水源、碳固持、释氧、吸收SO 2、吸收NO X、滞尘、降温、降噪8项城市绿地生态系统服务指标,对其价值进行了估算,并采用全排列多边形图示指标法对城市绿地生态系统服务进行评价。结果表明:2007—2018年,延吉市城市绿地生态系统服务价值总体呈现增长趋势,在12年间,总价值增加约1941×10^(4)元,其中,2018年较2017年总价值增加1452×10^(4)元。城市绿地生态系统服务等级呈现出“升高—降低—平稳—升高”的趋势。该研究可为延吉市城市绿地系统的合理规划与科学管理提供理论依据,为城市的可持续发展提供建议。

As an important part of the urban composite ecosystem,urban green space plays an important role in the sustainable development of cities.This paper took Yanji City,the core city of the Tumen River area as the research object,and used statistical data from 2007 to 2018 to select 8 cities for water conservation,carbon sequestration,oxygen release,SO 2 absorption,NO X absorption,dust retention,temperature reduction,and noise reduction Greenbelt ecosystem service index,its value was estimated,and the urban greenbelt ecosystem service was evaluated by the method of full array polygon icon.The results showed that from 2007 to 2018,the value of the urban green space ecosystem services in Yanji City presented an overall increasing trend.During the 12 years,the total value increased by about 1941×10^(4) yuan,of which,in 2018,the total value increased by 1452×10^(4) yuan compared with 2017.The service level of urban green space ecosystem shows a trend of"increasing-decreasing-stable-increasing".Through the research of this article,it can provide a theoretical basis for the rational planning and scientific management of the urban green space system of Yanji City,and provide suggestions for the sustainable development of the city.
