对河流生态系统服务功能的定量评估,有助于全面认识河流的价值,并且为合理利用水资源和科学管理整个流域提供决策依据。文章在对河流生态系统服务功能分类的基础上,结合数据的可获得性,对大汶河河流生态系统服务功能进行了初步评估,研究结果表明,2010年大汶河河流生态系统服务功能总价值为581 727.06万元,各项服务功能价值量由高到低排序为调蓄洪水、贮水、水产品生产、水供给、休闲娱乐、净化环境、提供生境、河流输沙和水力发电。
Quantitative evaluation of the river ecosystem services function is helpful to fully realize the value of the river and offer the decision basis for rational use of water resources and scientific management of the entire valley.Based on the classification of the river ecosystem services function,a preliminary assessment of Dawen river ecosystem services function using the available data was given in the paper.The results showed that the total value of Dawen river ecosystem services function was 5,817,270,600 Yuan in 2010.The values of various services function from high to low were in such order as flood regulation,water storage,aquatic production,water supply,leisure entertainment,environment purification,providing wildlife habitat,river sediment,hydro-power.
