The Study Of Xi'an Chanba Wetland Functions

Wetland as one of the three major ecosystems of the earth,has a very important ecological function.Mainly for the protection of ecological diversity,slow runoff and flood storage and drought,climate regulation,degradation of pollution and water purification,water conservation,leisure and tourism and urban construction and other functions.Urban wetlands as a special form of wetlands,the same for the human has a pivotal role.Scientifically understand the theory and function of urban wetland.First of all,is conducive to human protection of urban wetlands,scientific development and utilization of urban wetlands.Second,for the city planning and residents live and work the same significance.Xi'an Chanba urban wetland as a typical representative,to study its wetland function,for the Xi'an urban wetland protection,planning and construction play a very important practical significance.In this paper,Xi'an Chanba urban wetland is used as the research area to collect relevant literature,data and theoretical knowledge,and carry out field investigation.The relevant data and data about the environmental status of the city of Chanba are obtained.Through research,get the following main understanding and conclusions:(1)Xi'an Chanba urban wetlands have become the habitat of many wetland flora and fauna because of the function of wetland conservation of biodiversity.(2)Xi'an Chanba urban wetlands play a role in mitigating runoff and flood storage and drought prevention,compared with the previous,the river flow rate slowed down,the construction of reservoirs and lakes to store precipitation and accumulation of floods.(3)As a large area of wetland in Xi'an,Chanba urban wetland to a certain extent,improve the city heat island effect.(4)Chanba urban wetlands not only absorb water pollution,but also the air pollutants.adsorption and degradation,played a role in the degradation of pollution and purification of water quality.(5)Chanba urban wetlands as a large area of water,transformation of rivers and clear the runoff,the two rivers to improve the water storage capacity in the rainy season can effectively cut off the precipitation.(6)Chanba urban wetland is the most concentrated area of tourist attractions suchas Xi'an City Wetland Park,Yanming Lake,Peach Lake,Chanba City Wetland Park and the Expo is the best choice for tourists and leisure.(7)Xi'an to build an international metropolis to protect,planning and constructionof Chanba urban wetlands,while real estate development,consular district and schools and other infrastructure construction,improve the city of Chanba urban wetland level.
