摘要 :进入21世纪以来,我国各地区为寻求经济的快速增长,投入大量的财力、物力进行工业等污染企业的建设生产,而其向水环境排入了大量污染废物、废水,引起了不同程度的水环境的污染,这些水环境问题的产生削弱了城市水环境的承载力,影响了城市水环境的可持续发展。
本文以邳州市为实证,采用层次分析法,计算研究2008年~2013年邳州市的水环境承载力状况。依据计算出的数据结果,建立邳州市吹冰年来的水环境分承载力和综合承载力变化趋势图,研究分析得出吹冰年来邳州市水环境综合承载力总体呈上升趋势,表明邳州市水环境承载力在不断提高。并在此基础上分析影响城市水环境分承载力和水环境综合承载力变化的因素,并对未来邳州市水环境承载力的发展进行预测和分析。40319 毕业论文关键词:水环境承载力 ;层次分析法; 邳州市
Water Environmental Carrying Capacity Study of Pizhou
Abstract:In the 21st century, the region in search of rapid economic growth, a lot of financial and material resources for the construction industry and other polluters produce, and its large number of pollution discharged into the waste water to the water environment, causing varying degrees of water pollution of the environment, resulting in the weakening of the water environment bearing capacity of urban water environment, affecting the sustainable development of urban water environment.
In this paper, we calculate the water environment carrying capacity of Pizhou with AHP. According to the calculated results, we establish Pizhou city water environment and comprehensive carrying capacity trend Graphics in six years. Research results water environment bearing capacity of the overall upward trend in six years, suggesting that it continues to increase. And the effect of urban water environment sub-factors bearing capacity and water environment carrying capacity based on this change, and to predict and analyze the future development of water environmental carrying capacity in Pizhou.
