皖河流域治水与绿色经济转型研究

探讨皖河流域治水与绿色经济转型的关系及其相应的政策引导与支持.论证暴雨引发的洪涝灾害和水土流失是皖河流域经济发展的制约因素.皖河流域洪水发生期长,洪水过程具有“四大、两快、一短”的特征.径流量与含沙量波动呈正相关,峰值同时出现,上游支流的含沙量大于干流.以治水为中心,全面开发水力资源,发展生态农业、旅游业,退田还湖,发展湿地产业、避洪农业,保持园地、耕地的绿色覆盖,实现经济发展与生态保护有机结合,推进皖河流域绿色经济转型是必要的,也是可行的.

Flood Control in Wan River Basin and the Transformation of Green Economy

The relationship between the flood control of Wan River basin and green economy as well as the related policies and regulations are investigated in this paper. The economic development constrains in Wan River basin is considered to be the flood and soil erosion which caused by the rainstorm. The flood of Wan River basin has long period ,showing the characteristics of ＂four large, two fast and one short＂. The fluctuation of sediment concentration is positively related to the varied runoff ,and the peak value of them appears at the same time. The sediment concentration of the upstream tributaries is greater than that of the main stream. The future work should focus on the flood control and the full exploitation of hydropower resource as well as the development of eco--agriculture,eco-tourism. In order to realize the combination of economic development and ecologic protec- tion, there are still much work to do ,such as ＂returning farmland to lake＂, ＂the development of wetland industry and anti-flood agriculture＂ and ＂maintaining the green cover of arable land＂. Thus, it＇s necessary and also feasible to promote transformation of green economy in Wan River basin.
