摘要: 生态系统服务直接关系人类的福祉,是当前国内生态文明建设的重要组成内容之一。受数据源精准性、时序性等方面的限制,在全国尺度下开展的常态化生态系统服务价值核算尚存在缺失。本文首先根据生态系统类型的内部结构、功能和内容指标的概念语义构建地理国情地表覆盖与中国陆地生态系统分类内容指标转换表达关系,并生产了全国陆地生态系统矢量化数据。然后,应用反映植被生理特征指标参数(EVI、NPP和生长季长度)优化的当量因子法模型,引入不同尺度下多粒度变换的地理格网空间化表达技术,设计和开展依托矢量化地理国情普查成果的生态服务价值数据集的生产,实现了生态系统服务价值核算的精准化、常态化,满足了多尺度下生态服务价值动态变化监测的需求。本文按照上述生态系统服务价值核算方法计算了中国陆地生态系统服务价值总量和供给、调节、支持、文化服务子功能价值量1 km×1 km格网数据,核算出2015年全国生态系统服务价值总量为402 503.54亿元。通过与早期成果对比,该成果可以满足不同尺度对粒度变换的要求,核算结果可靠,可为当前全国尺度下的生态补偿政策和补偿标准的制定提供数据支撑。

Abstract: Ecosystem services are directly related to the well-being of human beings, and it is one of the important components of the construction of ecological civilization in China. There is still a lack of regular ecological service value accounting at the national scale because of the limitations of precision and time series data. In this study, we rebuilt the representation relationship between land cover data of geographical conditions and ecosystem classification based on the internal structure and function of ecosystem type, and the semantic concept of content index. The vector data of China's terrestrial ecosystem are produced. Then, we used equivalent factor model through the optimization of the vegetation feature index that reflect the vegetation physiological characteristic (EVI, NPP and growing-season length), and introduced geo grid spatial expression technology suitable for multi granularity transformation under different scales is applied, carrying out the production design of ecosystem service value data set based on vectorization data of national census geography. Production design realizes the precision and normalization of ecosystem service value accounting, meets the needs of dynamic monitoring of ecosystem service value under different scales, and completes the production of ecosystem service value data set under the national scale. According to the above ecosystem service value accounting method, the total ecosystem service value and the supply, regulation, support and cultural service sub function service value 1 km×1 km grid data are produced. The total terrestrial ecosystem service value of China in 2015 is 40.25×1012 CNY. The result is reliable and can meet the requirements of different scales for granularity transformation compared with earlier results. It will provide data support for the current national scale of horizontal ecological compensation policy.
