生态系统生产总值核算理论在生态文明评价中的应用——以三亚市文门村为例

乡村生态文明建设是海南生态省建设的重要内容。通过培育"文明生态村"、打造"美丽乡村",海南省乡村生态文明建设进入提质增效的生态产业化阶段,为乡村迎来了发展机遇。生态系统生产总值核算可以通过在乡村尺度上计算生态系统产品与服务的价值,起到监督、评价生态文明建设进展,探寻生态保护与乡村经济发展的平衡点,为实现彼此增益提供科学的数据支撑。同时,生态系统生产总值核算可以客观呈现当前乡村的生态价值,以此可以吸引资本、技术、人才等要素向农村流动,推动绿水青山变成金山银山。研究以海南省三亚市天涯区文门村为例,基于生态系统生产总值核算理论,对其生态系统产品与服务功能量和价值量进行核算。结果表明,文门村2017年生态系统生产总值是10297.79万元,生态系统产品价值占24.93%,调节服务价值占75.07%,单位面积生态系统生态总值为5.06万元/hm²。调节服务价值中,水源涵养、洪水调蓄、固碳释氧和空气净化价值分别为3287.44万元、1593.32万元、2815.31万元和34.72万元;林地对生态调节服务价值的贡献最大,达到5378.33万元,约占总间接价值的69.57%,其...

Application of the gross ecosystem product accounting theory on rural ecological civilization assessment in Hainan Province: A case study of Wenmen Village in Sanya

Construction of rural ecological civilization is one of the major projects in the ecological conservation of Hainan Province. By cultivating "Civilization Eco-Villages" and creating "Beautiful Villages", the ecological civilization in Hainan Province has gradually advanced in depth, and it has ushered in a rare opportunity for development in the rural areas. The gross ecosystem product (GEP) accounting can play the role of evaluating the performance of ecological civilization through calculating the values of ecosystem products and services, and eventually supply the scientific data to decision makers for finding the balance between ecological protection and rural economic development in the future. At the same time, it can be used to reveal the current resource values of the village that will help to attract more capital, technology, talents and other to the rural area, and make lucid waters and lush mountains invaluable assets. In this paper, GEP of Wenmen Village, Tianya District, Sanya City, Hainan Province was accounted as a case study. The results showed that the GEP of Wenmen Village in 2007 was 10297.79×10⁴ yuan and the value per unit area was 5.06×10⁴ yuan/hm². The value of ecosystem products accounted for 24.93% and the value of ecosystem regulation services accounted for 75.07%. Among the value of services, the values of water conservation, flooding mitigation, C fixation, oxygen production, and air purification were 3287.44×10⁴ yuan, 1593.32×10⁴ yuan, 2815.31×10⁴ yuan, and 34.72×10⁴ yuan, respectively. The forest land contributed the most to the value of ecological regulation services, accounting for 69.57% of the total value, followed by the farmland (14.86%) and orchard land (11.66%). The study suggests that, with the future strengthening of rural ecological civilization construction, including the improvement of nature resource management system, and the integration of ecological agriculture and rural tourism, it is necessary to improve the content of accounting.
