香格里拉市泥炭沼泽生态系统服务功能价值评估

香格里拉市高寒地区分布有众多泥炭沼泽生态系统，在云南省具有典型性、代表性，在湿地生态系统功能调节过程中具有不可估量的作用。根据《云南省泥炭沼泽碳库调查报告》,结合香格里拉市泥炭沼泽生态系统特点，构建了泥炭沼泽生态系统服务功能价值评估指标体系，评估了支持功能、调节功能和文化功能3项服务功能价值，包括8个具体评价指标。估算结果表明，香格里拉市泥炭沼泽生态系统服务功能总价值为5.99亿元/a,单位面积价值为110.86元/(m²·a),其中：间接价值占总价值的95.32%,蓄水调洪、固氮释氧以及气候调节价值最显著。

Value Evaluation of Peatlands Ecosystem Services in Shangri-La City

There are many peatlands ecosystems in the alpine region of Shangri-La City, which are typical and representative in Yunnan Province, and play an immeasurable role in the regulation of wetland ecosystem functions. Based on the Investigation Report on Carbon Storage of Peatlands in Yunnan Province, combined with the characteristics of the peatlands ecosystem in Shangri-La City, this paper constructed a peatlands ecosystem services value evaluation index system, and evaluated 3 services of support function, regulation function and cultural function, including 8 specific evaluation indicators. The estimation results showed that the total value of the peatlands ecosystem services in Shangri-La City was 599 million yuan/a, and the unit area value was 110.86 yuan/(m²·a), of which the indirect value accounted for 95.32%, and the value of the water storage and flood regulation, the nitrogen and oxygen release and the climate regulation was the most significant.
