【摘要】：城市生态环境是人类繁衍生息的重要基础,对其在时间和空间层面的演进趋势和规律的认识,有助于优化和提升其质量。在提出利用相关分析、关联耦合分析两种方法对上海市生态环境进行时空演化特征和优化途径研究的思路/技术路线的基础上,采用相关性分析方法,计算获得了上海市2000-2011年的大气环境、水环境、废弃物处理、绿化水平若干要素之间及要素群内部的皮尔逊相关系数;计算获得了上海市2012年各区县的若干生态环境要素与城市空间发展强度、综合生态安全水平、工业综合能耗等指标的皮尔逊相关系数数据。采用关联耦合分析方法,在时间角度,将上海市的生态环境要素分为质量表征指标和对生态环境质量产生直接或间接影响的指标两类,计算荻得了上海市2000—2011年间两类指标的关联系数、关联度、耦合度和协调度;在空间角度,计算获得了上海市17个区县的人口经济要素群与生态环境要素群的关联度、耦合度和协调度。基于时间和空间角度的相关性和关联耦合分析方法获得的各类结论,兼顾考虑上海生态环境要素群指标对上海人均期望寿命的影响和作用,从削减(降低)不利因素,提高(增加)有利因素等角度,提出了优化上海生态环境的若干建议。
[Abstract]:Urban ecological environment is an important basis for human reproduction. Understanding the evolution trend and law of urban ecological environment in time and space level is helpful to optimize and improve its quality. The correlation analysis method is adopted on the basis of studying the spatial and temporal evolution characteristics of Shanghai ecological environment and the way of optimization. The Pearson correlation coefficients of atmospheric environment, water environment, waste disposal and greening level of Shanghai from 2000 to 2011 were obtained. In 2012, some ecological environmental factors and the intensity of urban spatial development were obtained, and the comprehensive ecological security level was obtained. Pearson correlation coefficient data of industrial comprehensive energy consumption etc. Correlation coupling analysis method is used in time angle. The factors of ecological environment in Shanghai are divided into two categories: the index of quality representation and the index which has direct or indirect influence on the quality of ecological environment. The correlation coefficient, correlation degree, coupling degree and coordination degree of the two kinds of indexes were calculated from 2000 to 2011 in Shanghai. From the spatial point of view, the correlation degree between the population and economic elements group and the ecological environment factor group in 17 districts and counties of Shanghai was calculated. Coupling degree and coordination degree. Based on the correlation and correlation analysis methods of time and space, all kinds of conclusions are obtained, taking into account the impact and effect of Shanghai eco-environmental factor group index on the average life expectancy of Shanghai. From the point of view of reducing (reducing) unfavorable factors and improving (increasing) favorable factors, some suggestions for optimizing Shanghai's ecological environment are put forward.
