生态系统服务社会价值与生态价值的权衡与协同关系——以普达措国家公园为例

以香格里拉普达措国家公园为研究区，借助SolVES模型和InVEST模型，分别度量其社会价值（美学价值、文化价值、游憩价值）和生态价值（生境质量、碳储量、水源供给）的空间特征，并运用双变量空间自相关分析对二者空间权衡与协同关系进行研究。研究表明：① 社会价值的高值区呈“多核心，多条状”的空间格局，社会价值指数高达8.6（该指数介于1~10），且距水体的距离越近对社会价值的贡献越大（贡献度为45.9%）；② 生态价值良好及优的空间范围占园区面积的1/2（49.91%），主要位于原始森林保存良好的碧塔海片区和尼汝东北部扎诺一带；③ 社会价值与生态价值之间存在显著的空间依赖性，其中社会价值低，生态价值高的区域是园区最主要的空间聚集特征。该研究可为生态系统服务的可持续管理决策提供科学依据，以及有助于完善基于生态系统服务的社会?生态系统分析理论框架。

Trade-offs and Synergies Between Social Value and Ecological Value of Ecosystem Services: A Case Study of the Potatso National Park

Based on the perspective of coupled social-ecological system, scientific measurement of ecosystem service trade offs and synergies plays a vital role in regional sustainable development, ecological security, and human well-being. In order to promote the sustainable development of ecosystem services in nature reserves and improve human well-being, taking Potatso National Park as the research area, this article measures the spatial characteristics of its social value (aesthetic value, cultural value, recreation value) and ecological value (habitat quality, carbon storage, water yield ) with the help of SolVES model and InVEST model. Then the spatial trade-off and synergy relationship between social value and ecological value of Potatso National Park is deeply analyzed using bivariate spatial autocorrelation method. The results show that: 1) The hotspots of social value exhibit a ‘multi-core and multi-strip’ spatial pattern, with an 8.6 of social value index (the index is between 1-10), and the closer it is to the water body, the greater its contribution to social value (the contribution is 45.9%). 2) Relatively high and high spatial range of ecological value accounts for half of the park area (49.91%), mainly located in Bitahai Lake area and Zano area in the northeast of Niru with well-preserved virgin forest. 3) There is a significant spatial dependence between social value and ecological value, among which the areas with low social value and high ecological value are the main spatial aggregation characteristics of the park. This study provides a scientific basis for sustainable management decision-making of ecosystem services and help to improve the theoretical framework of social-ecological system based on ecosystem services.
