河流生态系统是重要的生态系统类型之一,其具有的生态资产对人类社会有重要意义。将河流及其自然资源、生态环境为人类提供的福利和服务作为一种资产进行定量评估有助于全面认识河流的价值,对河流保护及其科学利用具有重要意义。文章通过建立合理的河流生态资产评估框架,将黄河生态资产分为河道内生态资产、河岸带生态资产与河口生态资产三个部分进行了初步评估。基于目前的数据基础和研究成果评估得出的黄河生态资产的价值总量为1 127.82亿元,占黄河流域各省(市、区)2008年GDP的1.27%。结合黄河水资源管理的现状,提出了黄河河流生态资产保护的适应性管理建议。
River ecosystem is one of the important ecosystem types, and its ecological assets have great significance to human society. The quantitative assessment of the river and its natural resources and ecological environment as an asset to the welfare and services provided by human beings helps to fully understand the value of rivers and is of great significance to the protection of rivers and their scientific utilization. This article makes a preliminary assessment of the ecological assets of the Yellow River by dividing the Yellow River into three parts: the ecological assets of the river, the ecological assets of the riparian zone and the ecological assets of the estuary by establishing a reasonable evaluation framework of the ecological assets of the river. Based on the current data foundation and research results, the total value of the ecological assets of the Yellow River reached 112.782 billion yuan, accounting for 1.27% of 2008 GDP of all provinces (cities, districts) in the Yellow River Basin. Combined with the status quo of the Yellow River water resources management, this paper puts forward the adaptive management suggestions for the ecological assets protection of the Yellow River.
