【摘要】：银川有“塞上的湖城”动人名字,湿地有着强大的水文循环,物质循环的能量循环作用,是水分、无机污染物、有机物质的转换站,可以作为碳的“源头”和“汇总”,因此其生态地位每年都在提高。湿地发挥着生态保护,物种保护,生态旅游,生物质产品供给和环境调节等多种功能,为濒危物种生存,也为人类发展提供了保障。随着工业文明的浪潮席卷全球,社会的飞速发展带来了世界人口的大量增加,而工农业的不断壮大则加速了人类对湿地的开发步伐,由于过度的使用和浪费,目前全球天然湿地日益减少,食物多样性的逐渐单纯,经济功能效益下降,各国开始对湿地的保护与关注走上议程。国际社会越来越认识到保护湿地的特别是对湿地进行生态修复的重要性和紧要性,从最初的重点保护水禽的狭隘观点转变成为湿地保护的合理利用等各个方面。当今国内学术界均已对湿地问题产生重视,其研究也处于前沿领域。目前,中国在此方面面临着一个严峻的现实,那就是天然湿地数量减少、质量下降。中国是个人口大国且人口一直保持着高增长率,一方面农业用地在不断扩张,另一方面在大力发掘资源促进经济发展,对湿地的过度开发导致其面积大幅缩小,其功能和效益等也严重下降;加上无节制地捕捞、狩猎、砍伐、采挖等,严重破坏了湿地生态;废水、污水等长期排向湿地,极大地污染了其水质,造成环境损害。本文选取银川为样本,重点分析湿地对该市生态系统的重要性,同时关注该市湿地的现状及薄弱之处。为有效保护和重建银川湿地,健全其生态系统,从而达到美化银川市生态环境的目标,应积极开展研究工作,借助种种有力措施合理开发利用银川湿地资源,将银川打造成一个典型城市景观湿地典范,既有植物和鸟类保护,同时还可以提供资源供科研教育,可开发旅游项目,进行水资源保护。通过借鉴国内外生态景观环境评价及其建设过程中生态学理念和方法,结合生态学、人居环境学、地理学、人类行为学等多学科理论的基础之上研究其修护关系提出有效措施展望未来。
[Abstract]:Yinchuan has the moving name "Lake City on the Corridor." Wetlands have a strong hydrological cycle, a material cycle of energy circulation, and a conversion station for water, inorganic pollutants, and organic matter. It can be used as the "source" and "aggregate" of carbon, so its ecological status is improving every year. Wetlands play many functions, such as ecological protection, species protection, ecotourism, biomass product supply and environmental regulation, to survive for endangered species. With the tide of industrial civilization sweeping the world, the rapid development of society has brought a large increase in the world's population, and the continuous expansion of industry and agriculture has accelerated the pace of human development of wetlands. As a result of excessive use and waste, the global natural wetlands are decreasing, the food diversity is becoming more and more simple, and the economic and functional benefits are declining. The international community is increasingly aware of the importance and urgency of the conservation of wetlands, in particular the ecological restoration of wetlands, From the narrow view of protecting waterfowl at first to the rational utilization of wetland conservation and other aspects. Nowadays, the domestic academic circles have paid attention to the wetland problem, and their research is also in the front field. China faces a grim reality in this regard, namely, the decline in the quantity and quality of natural wetlands. China is a populous country with a high rate of population growth. On the one hand, agricultural land is constantly expanding. On the other hand, it is vigorously exploring resources to promote economic development, and the overexploitation of wetlands has led to a substantial reduction in its area and its functions and benefits, as well as unrestrained fishing, hunting, logging, mining, and so on. Serious damage to wetland ecology, waste water, sewage and other long-term drainage to wetlands, greatly polluted its water quality, resulting in environmental damage. This paper selected Yinchuan as a sample to analyze the importance of wetlands to the city's ecosystem. In order to effectively protect and rebuild Yinchuan wetland, improve its ecosystem and achieve the goal of beautifying the ecological environment of Yinchuan City, we should actively carry out research work. With the help of various measures to develop and utilize the wetland resources of Yinchuan reasonably, Yinchuan can be made into a typical urban landscape wetland model, not only plant and bird protection, but also provide resources for scientific research and education, and develop tourism projects. Through drawing lessons from the ecological landscape environment assessment and ecological concept and method in the process of construction, combining ecology, human settlements, geography, Based on the theory of human behavior and other subjects, this paper puts forward some effective measures to forecast the future.
