大庆湿地类型及水生态能值分析

Types of Wetlands in Daqing and Analysis of the Water Ecological Energy Value

以大庆湿地为研究对象,结合大庆地区2007年LANDSAT TM遥感图形解译数据和实地调查数据,采用地理信息系统技术(GIS)分析了大庆湿地的类型,并选用能值分析法对大庆湿地水生态系统的生态效益进行定量的分析。水结构的能值分析表明,大庆工业产值用水约235.5 m3/万元,能值货币比率为3.862 2 GJ/元。对比水田用水的能值货币比率和工业用水的能值货币比率,水田用水的能值货币比率是工业用水的能值货币比率的18.8倍。水质能值的经济分析表明,受工业生产规模扩大、人口增长及生态破坏的影响,研究区湿地中所测定的总氮、总磷、电导率、COD都普遍超出标准值,水体环境呈现碱性偏高。假设大庆市水环境投入的污染物能量为1/3,则治理大庆水环境污染的费用为6.2亿元;若投入的污染物能量为1/5,则治理污染费用约3.8亿元。

This paper analyzes the types of wetlands in Daqing,and quantitatively analyses the wetland ecological benefit of the ecological water system of Daqing using energy value analysis based on Daqing district LANDSAT TM 2007 graphics interpretation data of remote sensing and field survey data,using the geography information system（GIS） technology.The energy value analysis of water structure shows that the industrial output per ten thousand yuan water in Daqing is approximately 235.5 m3,and the monetary ratio of energy value is 3.862 2 GJ/yuan.The contrast monetary ratio of energy value of paddy water consumption and that of industrial water consumption,monetary ratio of energy value of paddy water consumption is 18.8 times than that of industrial water consumption.The economic analysis of water energy value can show that influenced by the industry production scale,population growth and the influence of ecological destruction,the total nitrogen,phosphorus,conductivity,and COD in the wetlands in Daqing are generally higher the standard,and the alkaline in the water is also high.Suppose the pollutant energy of water environment input in Daqing is 1/3,it takes 620 million yuan to deal with water pollution;and if the input pollutant energy is 1/5,it takes about 380 million yuan to deal with water pollution.
