根據蘇南、蘇中、蘇北空間分布選取江蘇省的四個具有代表性的城市:南京、蘇州、泰州、徐州為研究區域,采用生態環境質量綜合指數、層次分析法,建立生態環境質量評價指標體系

摘要 :城市化的發展帶來了城市人口的急劇膨脹、城鎮土地的快速擴張和經濟的飛速發展,同時產生的一系列的城市環境問題,給生態環境造成了巨大的壓力。江蘇省作為我國的經濟大省,城市化率高于全國水平,隨之而來的生態環境問題也不容小視。本文根據蘇南、蘇中、蘇北空間分布選取江蘇省的四個具有代表性的城市:南京、蘇州、泰州、徐州為研究區域,采用生態環境質量綜合指數、層次分析法,建立生態環境質量評價指標體系,對2008-2013年江蘇省四個地級市的生態環境質量時空差異進行評價。結果表明:江蘇省城市生態環境質量總體上逐步改善。(1)蘇州市的綜合生態環境質量指數最高,南京市次之,徐州市和泰州市最低。(2)隨著時間的推移,蘇州市和南京市的城市綜合生態環境質量綜合指數增長,徐州市的綜合生態環境質量指數在2008-2011年上升,2011-2013年下降,整體處于上升趨勢;泰州市的綜合生態環境質量指數在2008-2011年下降,2011-2013年上升,總體處于上升趨勢。從江蘇省城市生態環境質量的變化可知,環境質量開始會隨著經濟的快速發展而惡化,之后又會因經濟發展水平的提高而得到改善,由此提出一些改善城市生態環境質量的建議。34686

Temporal and Spatial differences on Eco- environmental Quality of City in Jiangsu Province
Abstract:Urbanization has brought rapid expansion of the urban population, the rapid expansion of urban land and rapid economic development, and produced a series of urban environmental issues, the ecological environment has caused tremendous pressure.As China's Jiangsu province economy, the urbanization rate is higher than the national average, followed by urban environmental problems can not be overlooked. In this paper, four representative cities, locating in south, middle and north of Jiangsu province, respectively, were selected as the research areas. Nanjing,Suzhou, Taizhou, Xuzhou. The ecological environment quality evaluation system was established using the method of ecological environment quality index, the level of analysis, AHP, for 2008--2013 temporal difference of ecological environment quality in four prefecture-level city in Jiangsu province were evaluated. The results showed that:City ecological environmental quality of Jiangsu Province overall gradual improves. (1) Compared the overall index of ecological environment quality of the four cities, Suzhou was the highest, Nanjing second,then Xuzhou followed, while Taizhou was the lowest. (2) Over time, Suzhou City and Nanjing integrated urban ecological environmental quality index growth, Xuzhou overall ecological environment quality index in 2008 - rose in 2011, 2011 --2013 declined, the overall upward trend; Taizhou integrated ecological environmental quality in the city of 2008 - 2011 was down in 2011 - The 2013 rise, the overall upward trend. From changes in the urban ecological environment quality in Jiangsu Province, environmental quality will begin to deteriorate as the economy develops and, after due to increased levels of economic development and improved, thus some suggestions to improve the environmental quality of urban ecology.
