邢家渡引黄灌区废弃沉沙池生态修复模式研究

Ecological Restoration Model in Waste Sand Basin of Xingjiadu Yellow River Irrigation Area

2002年济南市邢家渡引黄灌区沉沙池停止使用,形成约204 hm2的沙地,已成为济南市区沙尘的源头之一。在确立邢家渡灌区废弃沉沙池治理模式和目标定位基础上,针对性地提出了林地生态修复模式、耕地生态修复模式、林地–耕地综合生态修复模式和湿地生态修复模式4种生态修复模式,充分发挥湿地的滞蓄洪水、水体净化、生态修复、景观旅游等功能,把废弃沉沙池湿地建设成为生态清洁型的生态涵养、生态修复、旅游发展、现代特色农业与高效节水示范区。邢家渡引黄灌区废弃沉沙池大部分土地可以以湿地模式来进行生态修复,在进行湿地生态修复的同时,还可以带动渔业、采摘农业以及旅游业等的发展,从而带来可观的经济效益。

The waste sand basin of Xingjiadu in Jinan was abandoned in 2002. About 204 hm^2 land was abandoned, which becomes sand-storm source of Jinan. Ecological restoration model of Yellow River irrigation area waste sand basin is important to regional development and environmental governance. On the basis of establishing development direction and goal orientation, this paper put forward four kinds of ecological restoration model ： ecological restoration model of forest planting, ecological restoration model of agricultural planting, comprehensive ecological restoration model of forest planting and agricultural planting, ecological restoration model of wetland, which plays the wetland flood storage and detention, water purification, ecological restoration, landscape tourism, and to rebuild waste sand basin wetland into eco-friendly type of ecological conservation, ecological restoration, tourism development, characteristic of modem agriculture and efficient water-saving demonstration area. Most of the waste sand basin of Xingjiadu can use the wetland model for ecological restoration, which drives the development of fishing, picking agriculture and tourism, and brings considerable economic benefits as well.
