摘要
本文应用市场价值法、旅行费用法和替代工程法等方法和前人的研究成果,对金沙江攀枝花河段的生态系统服务功能价值进行了计算。计算得出金沙江攀枝花河段的生态系统服务功能经济价值总量为280.62亿元/a,相当于攀枝花市2003年GDP的1.11倍,其中河流生态系统服务功能价值约为河流生态系统产品功能价值的28.45倍。各项功能的价值量中,贮水功能的价值量最大,为268.27亿元/a;提供生境的功能价值量最小,为0.02亿元/a。经过分析,所研究河段的贮水功能是其核心服务功能。因此,在河流管理中既要考虑到核心功能的发挥,又要兼顾其他功能的支持作用得以实现,为生态环境保护和可持续发展战略的实施提供重要的决策依据。
In this chievements of the paper, the market value method .traveling cost method 、engineering substitution method and the a- predecessors were used to evaluate the ecosystem services in Panzhihua section of the Jinsha River. The results showed that the total economic ecosystem value of the ecological services in Panzhihua section of the Jinsha River was about 280.62 hundred million RMB per year,which as much as 1.1 times the total GDP of the Panzhihua city in 2003. Among the value, the ecosystem value of the ecological services was 28.45 times as much as the ecosys- tem value of the ecological products. Among the value, water storage function contributed the largest at about 268.27 hundred million RMB per year; providing habitat function contributed the smallest at about 0.02 hundred million RMB per year. We analyzed that the water storage function was the core service function. So during the management of the river,we should think about the core function,but also think about how to guarantee the realization of the supports in other functions. We provide important basis for the protection of ecological environment and the adoption of sustainable development strategy.
