摘要:
长潭水库作为台州地区重要的饮用水水源地,对地区发展和社会稳定具有重要意义。选择长潭水库为研究对象,参考《浙江省湖库生态缓冲带划定与生态修复技术指南(试行)》划定湖滨带、缓冲带范围并开展生态修复实践。结果表明:长潭水库湖滨带总长度约97 km,分为山体型、自然滩地型、农田型、公路型、河口型、水库大坝型6种类型,长度占比分别为42.6%、25.3%、3.4%、20.6%、7.6%、0.5%;长潭水库缓冲带分为山体型、农田型、水库大坝型3种类型,面积分别为46.73、2.89、0.168 km2。在划定长潭水库湖滨带、缓冲带范围的基础上,识别其主要环境问题并选取重点生态修复区,从干扰去除、污染防治、生态恢复3个方面研究提出了具有针对性的生态修复对策,以期营造具有较强保护调节能力、人与自然和谐相处的水库岸带生态缓冲系统。
Abstract:As an important drinking water source in Taizhou City, Changtan Reservoir is of great significance to regional development and social stability. Taking Changtan Reservoir as the research object, the delimitation and ecological restoration of the lake littoral zone and lake buffer zone were carried out in Changtan Reservoir under the guidance of Technical Guide for Delimitation and Ecological Restoration of Ecological Buffer Zone of Lakes and Reservoirs in Zhejiang Province (Trial). The results showed that the total length of the lake littoral zone of Changtan Reservoir was about 97 km. The lake littoral zone was divided into six types, including mountain type, natural beach type, farmland type, road type, estuary type and reservoir dam type, accounting for 42.6%, 25.3%, 3.4%, 20.6%, 7.6% and 0.5% of the total length, respectively. The lake buffer zone of Changtan Reservoir was divided into three types, including mountain type, farmland type and reservoir dam type. The area of these three types of buffer zones was 46.73, 2.89 and 0.168 km2, respectively. Based on the delimitation of the lake littoral zone and lake buffer zone of Changtan Reservoir, the main environmental problems were identified and key ecological restoration areas were selected. From the aspects of disturbance removal, pollution prevention and ecological restoration, targeted ecological restoration countermeasures were proposed to create a reservoir ecological buffer system with strong capabilities of protection and adjustment, and harmonious coexistence between man and nature.
