湖南南山国家公园湿地生态系统服务价值评估

he valuation of wetland ecosystem services of Nanshan National Park in Hunan Province is an important step in promoting the national park to better serve human development. In order to focus on real human needs to promote the sustainable development of ecosystem service supply, this paper established a classification of ecosystem services based on human needs, and specifically divided it into 3 major categories: production of material goods, ecological safety and security, and social services. According to the three types of wetlands in the region，we considered and summarized the total value of wetlands by considering the differences in services provided by each type of wetlands and the importance of various services. The results revealed that the total value of wetland ecosystem services in Nanshan National Park was 3123.326×106 yuan, and the unit value was 3.646×106 yuan / hm2. The value of wetland ecological security services ranked first, accounting for 76.17% of the total value of wetland, followed by social services. Among the specific indicators, climate regulation, flood regulation, landscape recreation and hydropower generation occupied dominant positions. Distinguishing different types of wetlands, artificial wetlands had the largest contribution to the total service value, and swamp wetlands had the highest service value per unit. There were also differences in the core services provided by different types of wetlands, but in general, the people\'s demand for environmental safety was the strongest, and social demand had risen. The value of various services of wetlands contains a strong public demand for value realization. It is suggested that in the future, security needs should be safeguarded and the dominant service advantages of various wetlands should be maintained; the tourism economy should be developed rationally and other social needs should be taken into account for enhancement.
