【摘要】：近年来,中国城镇化发展迅速,同时资源的消耗和污染物质不断排放到周围的环境中,引发了一系列的生态环境问题。我国对生态环境建设不断重视,在国家号召振兴东北老工业基地以及各项方针政策的指引下,研究本溪市城镇化与水生态环境的响应及协调发展关系,并实现两者的协调发展,是一个有实际意义的课题。在总结国内外城市化与水生态环境相互关系研究的基础上,对城镇化指标和水生态环境指标进行选取并构建两者响应的评价指标体系,并对2000~2014年中两者的响应关系及协调发展进行定性的分析,主要结论如下:1、从人口、空间、经济、社会4个方面选取10个指标,对本溪市的城镇化水平进行测评,结果显示本溪市的城镇化水平已经进入快速发展的阶段。2、依据P-S-R模型建立水生态评价指标体系,分别从水生态环境压力、状态、响应三个方面选取10个指标进行测评,结果显示本溪市的水生态压力、状态、响应指数呈现各自的特点,水生态综合指数、水生态压力指数、水生态状态指数总体呈“U”型曲线,表明本溪市的水生态状况总体上有一个先变坏再变好的趋势,而水生态响应指标呈现总体上升的趋势,这体现了本溪市对环保的投入力度。3、通过建立本溪市城镇化与水生态环境的响应关系发现:依据发展特点,两者响应关系可以分为两个阶段,2000~2008年和2009~2014年,并且城镇化与水生态环境及其分量的响应关系呈现各自不同的响应函数,这表明“U”型曲线在实际例中的不同表现形式。4、通过建立本溪市城镇化与水生态环境的协调发展模型发现:本溪市经历了一个由城镇化发展滞后向水生态环境滞后发展的过程,其发展协调等级由勉强协调发展为良好协调状态。5、依据本溪市城镇化与水生态环境的测评、响应及协调发展关系研究,对本溪市的发展提出对策,即:本溪市应持续加强城镇化建设的速度和质量,同时要注重水生态环境的保护,做到城镇化发展与水生态保护兼顾。
[Abstract]:In recent years, with the rapid development of urbanization in China, the consumption of resources and the discharge of pollutants into the surrounding environment have caused a series of ecological and environmental problems. Under the guidance of the national call to revitalize the old industrial base in Northeast China and various policies, the paper studies the response and coordinated development of urbanization and water ecological environment in Benxi, and realizes the coordinated development of the two. On the basis of summarizing the relationship between urbanization and water ecological environment at home and abroad, the indexes of urbanization and water ecological environment are selected and the evaluation index system of their response is constructed. The qualitative analysis of the response relationship and coordinated development of the two from 2000 to 2014 shows that the main conclusions are as follows: 1, 10 indicators are selected from four aspects of population, space, economy and society, and the urbanization level of Benxi is evaluated. The results show that the urbanization level of Benxi City has entered the stage of rapid development. According to the P-S-R model, the evaluation index system of water ecology is established, and 10 indexes are selected from three aspects of water ecological environment pressure, state and response. The results showed that the water ecological pressure, state and response index of Benxi showed their own characteristics. The comprehensive index of water ecology, the index of water ecological pressure and the index of water ecological state showed a "U" curve in general. The results show that there is a trend that the water ecological status in Benxi City has a trend of first bad and then better, while the response index of water ecology has an overall upward trend. By establishing the response relationship between urbanization and water ecological environment in Benxi City, the response relationship can be divided into two stages: from 2000 to 2008 and from 2009 to 2014, according to the characteristics of development, the response relationship between them can be divided into two stages. And the response relationship between urbanization and water ecological environment and its components presents different response functions. This indicates that "U" curve has different forms of expression in practice. By establishing the coordinated development model of urbanization and water ecological environment in Benxi City, it is found that Benxi City has experienced a process from urbanization lagging behind to water ecological environment lagging. According to the evaluation, response and coordinated development relationship of urbanization and water ecological environment in Benxi City, the countermeasures are put forward for the development of Benxi City. That is, Benxi should continuously strengthen the speed and quality of urbanization construction, pay attention to the protection of water ecological environment, and achieve both urbanization development and water ecological protection.
