【摘要】：湿地与人类的生存、繁衍和发展息息相关,是自然界最富生物多样性的生态景观和人类最重要的生存环境之一,为人类的生产、生活提供多种资源,具有巨大的环境功能和效益,在抵御洪水、调节径流、蓄洪防旱、控制污染、调节气候、控制土壤侵蚀、美化环境及保护生物多样性等方面发挥着重要作用。炎陵县地处湘赣两大水系分水岭,湿地资源丰富,地位重要,但是炎陵县对于湿地的现状调查和保护对策的研究不是很深入。本文通过文献研究、实地调查和问卷调查的方法,对湖南省炎陵县的湿地情况进行了深入调查和分析,对炎陵县湿地保护的情况也做了实地调研和问卷调查,针对炎陵县湿地资源所存在的问题提出了建议和保护对策。主要结结论如下。1)炎陵县湿地现状主要包括河流湿地、沼泽湿地和人工湿地,河流湿地为炎陵县天然湿地的主体,高山沼泽湿地面积为全省最大,呈现山地湿地特点。2)炎陵县湿地内生物多样性丰富、珍稀濒危物种种类多,湿地资源多样,湿地景观旅游资源优势独特。3)但由于近期开发的人为因素,尤其是水电站建设泛滥,炎陵县湿地健康受到威胁,主要体现在有害生物呈不断增长,经济发展与湿地保护矛盾突出,河网湿地水体滞留问题严重,有害生物呈不断增长,湿地保护管理机制不畅,政府和群众保护湿地生态功能的意识不强,以及湿地保护研究和措施相对薄弱。4)并针对炎陵县的湿地资源现状和保护情况存在的问题提出了从土地和水域利用管理、湿地生物多样性保护、湿地污染控制管理、湿地恢复管理和可持续利用示范等方面加强湿地的保护和避免过度开发。
[Abstract]:Wetland and human survival, reproduction and development are closely related, is one of the richest biodiversity ecological landscape and the most important living environment of mankind, for the production of human life, providing a variety of resources, has great environmental functions and benefits, in flood defense, regulating runoff, flood and drought, pollution control, climate regulation and the control of soil erosion, plays an important role in beautifying the environment and the conservation of biological diversity. Yanling county is located in the two major river watershed, wetland is rich in resources, but the important status of Yanling County for the investigation and Protection Countermeasures of wetland is not very deep. Through literature research, field survey and questionnaire survey method the situation of wetland Yanling County of Hunan province conducted in-depth investigation and analysis, the Yanling County wetland protection situation also made investigation and questionnaire survey in Yanling County The existing problems of wetland resources and protection countermeasures and suggestions. The main conclusions are as follows..1) of wetland in Yanling county mainly include river wetlands, marsh wetland and artificial wetland, river wetland is the main natural wetland in Yanling County, the province's largest alpine wetland area, showing the characteristics of.2 mountain wetland wetland biodiversity in Yanling county) the rich, rare and endangered species diversity, wetland resources, wetland landscape tourism resources unique advantages of.3) but due to human factors developed recently, especially in the construction of hydropower station in flood, wetlands in Yanling county health is threatened, mainly reflected in a growing pest, economic development and wetland protection contradiction, river wetland water retention problem is serious, the pest is growing, wetland protection management mechanism is not smooth, the government and the masses to protect the ecological function of wetland and wetland protection consciousness is not strong, Study on protecting measures and relatively weak.4) and for the wetland resources and protection situation of Yanling County, the problems raised from the land and water use management, wetland biodiversity conservation, pollution control and management of wetland, wetland restoration management and sustainable utilization demonstration to strengthen wetland protection and avoid excessive development.
