基于三调数据的县级生态系统服务功能价值估算——以建瓯市为例

Value Estimation of Ecosystem Services at County Level Based on Three Survey Data:A Case Study of Jianou City

生态系统服务价值的定量评估可为自然资源合理利用及生态保护提供科学依据。基于此,本文以全国第三次土地调查数据作为基础数据,应用价值当量法对建瓯市生态系统服务功能价值进行估算。结果表明,建瓯市森林、农田、湿地、水域面积分别为370111.71 hm^(2)、29581.87 hm^(2)、567.75 hm^(2)、7586.59 hm^(2)。建瓯市生态价值总额为89.05亿元,其中,气体调节11.61亿元、气候调节9.20亿元、水源涵养24.40亿元、土壤形成与保护13.18亿元、废物处理5.96亿元、生物多样性保护11.05亿元、食物生产0.60亿元、原材料8.54亿元、娱乐文化4.51亿元。

The quantitative evaluation of ecosystem service value can provide scientific basis for rational utilization of natural resources and ecological protection.Based on this,this paper uses the third national land survey data as the basic data,and uses the value equivalent method to estimate the value of ecosystem services in Jianou City.The results show that,the area of the forest,farmland,wetland and water area in Jianou City is 370111.71 hm^(2),29581.87 hm^(2),567.75 hm^(2) and 7586.59 hm^(2).The total ecological value of Jianou City is 8.905 billion yuan,including 1.161 billion yuan for gas regulation,920 million yuan for climate regulation,2.440 billion yuan for water conservation,1.318 billion yuan for soil formation and protection,596 million yuan for waste treatment,1.105 billion yuan for biodiversity protection,60 million yuan for food production,854 million yuan for raw materials,and 451 million yuan for entertainment culture.
