鄱阳湖滨湖沙地生态保护与修复综合治理探讨
|
摘要
鄱阳湖滨湖沙地是我国湿润及半湿润地区的风沙化土地之一,风沙侵蚀严重影响了区域生态安全和粮食安全,亟待生态治理.本文探讨了流动沙丘、半流动半固定沙丘和固定沙丘3种类型的鄱阳湖滨湖沙地生态保护与修复综合治理技术体系,提出了营造植被生境、修复生态环境、保护生物多样性、促进综合利用、调整产业结构、发展多种经营、开展宣传教育、强化生态意识的综合治理方式.以都昌县和星子县为例,评价了综合治理的生态效益、经济效益和社会效益.可为鄱阳湖滨湖地区沙化土地治理、生态脆弱区生态保护和修复提供决策参考.
The sand land area at the lakeside of Poyang lake is one of the sandy lands in the humid and semi-humid areas of China,where the sandstorm erosion has seriously affected regional ecological security and food security and needs ecological management urgently. This paper discusses the three types'(mobile sand dunes,semi-flow semi-fixed sand dunes and fixed sand dunes)comprehensive management system of ecological protection and restoration methods.The following means are proposed: creating vegetation habitats and repairing ecological environment, protecting biodiversity and promoting comprehensive utilization, adjusting industrial structure and developing diversified operations, carrying out publicity and education and improving ecological awareness. Taking Duchang county and Xingzi county as examples,the ecological,economic and social benefits of comprehensive management are evaluated.It can provide decision-making reference for desertification control and ecological protection and restoration of ecologically fragile areas in the lakeside area of Poyang lake.
