【摘要】：随着城市化的进程,大量人口聚集到城市之中,这对于城市的生态环境提出了更高的要求,良好的生态环境得益于良好的城市绿地,其中一个重要的组成部分就是城市公园。城市公园所具有的生态服务功能对于环境质量的提升具有重要作用。本次研究在实地调查和文献研究的基础上,对城市公园生态服务功能、评估方法、评价体系进行了研究,并借助构建的体系分别对成都两个公园进行了生态服务功能评价。研究结果如下：(1)结合文献查阅法、调查问卷法、频度分析法构建了针对城市公园生态系统尺度的服务功能评价指标群。评价指标分别包含有涵养水源、固碳释氧、蒸腾吸热、吸收二氧化硫、空气滞尘、降低噪音、提供负离子、景观游憩以及社会效益。此外,通过对于评价方法的研究,分别选择了适应目标区域科学合理的价值评估方法。(2)在大量调查文献的基础上建立针对南方城市的基础科研数据库,分别对常见的园林树种叶面积指数、固碳、释氧、滞尘、蒸腾、吸收二氧化硫进行了汇总,建立了相对应的南方植物基础数据资料库。(3)通过实地调查结合评价体系、评价方法以及植物基础数据,分别对光华公园和新桂湖公园进行了生态系统服务功能评价。光华公园生态服务功能价值为107591492.25元,生态效益服务功能价值为26040105元,景观游憩功能价值为43726059.58元,社会效益功能价值为37825327.71元。新桂湖公园生态服务功能价值为64495779.40元,生态效益服务功能价值为21154759元,景观游憩功能为39635013.83元,社会效益服务功能价值37060061.5元。
[Abstract]:With the process of urbanization, a large number of people gathered into the city, which put forward higher requirements for the ecological environment of the city, and the good ecological environment benefited from the good urban green space. One of the important components is the city park. The ecological service function of the city park plays an important role in improving the environmental quality. The ecological service function, evaluation method, evaluation system of urban park were studied, and the ecological service function of two parks in Chengdu were evaluated with the aid of the constructed system. The results are as follows: 1. The evaluation index group of service function for the scale of urban park ecosystem is constructed by frequency analysis. The evaluation indexes include water conservation, carbon sequestration, oxygen release, transpiration and heat absorption, absorption of sulfur dioxide, air stagnation and noise reduction. Provide negative ions, landscape recreation and social benefits. In addition, through research on evaluation methods, Based on a large number of investigation documents, the basic scientific research database for southern cities was established, and the leaf area index, carbon sequestration, oxygen release and dust retention of common garden tree species were respectively selected. Transpiration, absorption of sulfur dioxide were collected, and the corresponding database of basic plant data in South China was established. The database was combined with evaluation system, evaluation method and plant basic data through field investigation. The ecosystem service function of Guanghua Park and Xingui Lake Park were evaluated respectively. The ecological service function value of Guanghua Park was 107591492.25 yuan, the value of ecological benefit service function was 26040105 yuan, and the value of landscape recreation function was 43726059.58 yuan. The social benefit function value is 37825327.71 yuan, the ecological service function value is 64495779.40 yuan, the ecological benefit service function value is 21154759 yuan, the landscape recreation function is 39635013.83 yuan, the social benefit service function value is 37060061.5 yuan.
