    Assessment method of watershed ecological asset value in the middle and lower reaches of the Yangtze River: A case study of the Xin'an River Basin

    • 摘要:
      研究目的 生态资产评估有助于理清区域生态资源本底,为建立健全自然资源监管技术体系,实施生态补偿政策提供科学依据,对于推动生态产品价值实现具有重要意义。
      研究方法 本文构建了生态资产价值评估的方法指标体系,通过集成土地利用、遥感影像、气象、地球化学以及社会经济等多源数据,开展生态资产存量、生态资产质量以及生态资产价值评估,并结合地理探测器探求生态系统服务价值的空间分异影响因素。
      研究结果 2020年新安江流域生态资产质量等级以良、中为主,分别占比80.96%、10.25%;生态资产存量综合指数为0.77,湿地、森林与园地占主要位置;流域生态系统服务价值为1334.48亿元,森林资源与水资源价值占比最高,坡度、高程和年降水量为影响生态系统服务价值空间分异的主要驱动因子。
      结论 新安江流域生态资产价值较高,森林与水资源是流域生态系统服务的主要载体,自然禀赋条件对其生态系统服务价值空间分异的影响程度大于社会经济因素。

       

      Abstract:
      This paper is the result of environmental geological survey engineering.
      Objective The objective of this research endeavor is to evaluate the ecological asset value, thereby facilitating an enhanced comprehension of the foundational aspects of regional ecological resources. By furnishing a scientific foundation for the establishment of comprehensive natural resource management systems and the effective implementation of ecological compensation policies, this study assumes a pivotal role in promoting the realization of the value of ecological products.
      Methods This study presented a comprehensive approach for assessing the value of ecological assets. The methodology encompasses the integration of diverse data sources such as land use, remote sensing imagery, meteorology, geochemistry, and socio−economic indicators. Through this integrated framework, evaluations were performed to determine the stock, quality, and value of ecological assets. Furthermore, geographical detector tool was employed to investigate the spatially varying factors that influence the values of ecosystem services.
      Results The ecological asset quality in the Xin'an River Basin is primarily in the good and moderate levels, accounting for 80.96% and 10.25%, respectively. The comprehensive index of ecological asset stock in the Xin'an River Basin in 2020 is 0.77. Wetland, forest land, and cultivated land occupy prominent positions. The value of ecosystem service is estimated at 133.448 billion yuan, with forests and water resources having the highest proportion Slope, elevation, and annual precipitation are the main driving factors of spatial differentiation in the value of ecosystem services.
      Conclusions Xin'an River Basin has a high ecological asset value. Forests and water resources are the main carriers of ecosystem services in the basin. The impact of natural endowments on the spatial differentiation of ecosystem service values is greater than that of socio−economic factors.
