艾比湖湿地生态效应能值评价

Emergy Evaluation on the Ecological Effect of Ebinurd Wetland

湿地是地球上具有多功能的独特生态系统,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。内陆干旱区的湿地则因其所处地理环境的特殊性更具有巨大保护价值。艾比湖湿地在我国内陆荒漠自然生态系统中具有一定典型性。其生态系统极不稳定,具有很强的敏感性和脆弱性。人类社会经济的迅猛发展,引起一系列以土地荒漠化为代表的生态逆向演替,严重的水土流失和锐减的生物多样性使其不可更新资源的能值投入远远超过其可更新资源,同时,肆虐的盐尘严重危害着天山北坡经济带甚至更远地区工、农、牧业生产和人们的生活环境。从能值角度评价环境的贡献,注重其生态效应,以期引起人们警醒,加强湿地资源的保护和管理,维护其可持续发展。

Wetland is a special ecological landscape system and the most crucial survival environment of human being for its many important functions such as biodiversity.Especially in inland arid region,wetland should has the more great protection value for the special geography environment,and Ebinur lake wetland is a typical example in desert natural ecosystem of inland which its ecosystem is extremely unstable and vulnerable.With the rapid development of our social economy,lots of reverse ecological succession has appeared such as land desertification,biodiversity reduction and other un-renewable resource exhaustion.The negative effects have threaten the health of people and the production of all kinds.In order to remind human paying more attention to ecological effect and maintenance the nature resource to sustainable use,it is very important to adopt emergy method to evaluate natural environment contribute.
