Evaluation of Marsh Wetland Ecosystem Service Value in Yunnan Province
Based on 2021 as the reference year,the wetland ecosystem services in Yunnan Province were divided into four types of supply services,ecological regulation services,support services and social serv-ices,and the value of each service was estimated.The results showed that the total value of the ecosystem services was 30.329 billion yuan,with a unit area value of 747 400 yuan/(hm2·a);among the four types of services,the value of ecological regulation services(16.963 billion yuan)＞the value of supply services(11.551 billion yuan)＞the value of social services(1.341 billion yuan)＞the value of support services(474 million yuan);the highest value of ecosystem services provided by marsh wetland in Yun-nan was Deqen Prefecture(15.57 billion yuan).The results can provide scientific basis for the protec-tion and management of marsh wetlands and the formulation of ecological compensation policies in Yunnan Province.
