达里诺尔湖湿地生态系统服务价值评价

生态系统服务功能是生态系统与生态过程所形成及所维持的人类赖以生存的自然环境条件与效用,对其服务价值进行货币化评价,可以推动自然资源可持续利用,促进区域生态环境保护。以达里诺尔湖湿地为研究对象,结合达里诺尔湖湿地生态系统的结构、特征及其生态过程特点,通过资料搜集与实地调研,运用资源经济学理论和方法,对达里诺尔湖湿地生态系统服务价值进行了划分。构建了达里诺尔湖湿地生态系统服务价值评价指标体系,并对其进行了价值评价。评价结果显示达里诺尔湖湿地的服务价值为93.70×10⁴万元,其中直接使用价值为2.19×10⁴万元,占比为2.36%,间接使用价值为91.51×10⁴万元,占比为97.66%。各项生态系统服务功能中以调节空气湿度价值最大,为82.76×10⁴万元,占总服务价值的88.32%。

The Service Value of Wetland Ecosystem in Dalinor Lake: Evaluation

Ecosystem service function is the natural environment condition and utility, which is formed and maintained by ecosystem and ecological process, and important for the survival of human beings. The monetized evaluation of its use value can promote the sustainable utilization of natural resources and promote the regional ecological environment protection. This study took the Dalinor Lake wetland as the research object, analyzed its structure, features and ecological process characteristics of the wetland ecosystem. Based on data collection and field investigation, the service value of the Dalinor Lake wetland ecosystem was classified by the theory and method of resource economics. The study constructed the use value evaluation index system of the Dalinor Lake wetland ecosystem, and evaluated its service value. The evaluation results showed that the service value of the Dalinor Lake wetland was 93.70×10⁸ yuan, of which the direct use value was 2.19×10⁸ yuan, accounting for 2.36%, and the indirect use value was 91.51×10⁸ yuan, accounting for 97.66%. Among all the ecosystem service functions, the value of adjusting air humidity was the largest, which was 82.76×10⁸ yuan, accounting for 88.32% of the total service value.
