运用SPSS13.0数理统计软件,建立都市圈经济-资源-环境系统(ERE)评价指标体系,引入层次分析法,构建ERE系统发展函数,以武汉城市圈为例,系统揭示武汉城市圈ERE系统各子系统发展的时空规律:(1)时间演化上,经济子系统保持指数增长速度,整个圈域经济处于高速运行中;资源子系统波动变化明显,整体上呈先上升、再下降、后上升的倒S型曲线,表现为缓慢上升、快速下降、迅速抬升三个阶段特征;环境子系统整体上呈指数律快速发展,除了在1999年出现一定程度下滑外,整个环境系统呈良性发展态;(2)空间分异上,经济子系统城际差异明显,形成以武汉为核心的三等级圈层结构,资源环境子系统整体受经济发展方式影响显著,呈现三集团发展态势。由于经济发展、资源环境条件、历史基础、政策机制等差异,武汉城市圈城际资源环境系统整体发展空间不对应,形成四大类型:资源环境好—经济发展型、资源环境好—经济滞后型、资源环境差—经济发展型、资源环境差—经济滞后型。
運用SPSS13.0數理統計軟件,建立都市圈經濟-資源-環境繫統(ERE)評價指標體繫,引入層次分析法,構建ERE繫統髮展函數,以武漢城市圈為例,繫統揭示武漢城市圈ERE繫統各子繫統髮展的時空規律:(1)時間縯化上,經濟子繫統保持指數增長速度,整箇圈域經濟處于高速運行中;資源子繫統波動變化明顯,整體上呈先上升、再下降、後上升的倒S型麯線,錶現為緩慢上升、快速下降、迅速抬升三箇階段特徵;環境子繫統整體上呈指數律快速髮展,除瞭在1999年齣現一定程度下滑外,整箇環境繫統呈良性髮展態;(2)空間分異上,經濟子繫統城際差異明顯,形成以武漢為覈心的三等級圈層結構,資源環境子繫統整體受經濟髮展方式影響顯著,呈現三集糰髮展態勢。由于經濟髮展、資源環境條件、歷史基礎、政策機製等差異,武漢城市圈城際資源環境繫統整體髮展空間不對應,形成四大類型:資源環境好—經濟髮展型、資源環境好—經濟滯後型、資源環境差—經濟髮展型、資源環境差—經濟滯後型。

This paper establishes an ERE evaluation index system in metropolitan area with the mathematical statistics SPSS13.0 and creates a function of the ERE system development by introducing Analytic Hierarchy Process. Then this arti- cle took Wuhan Metropolitan Area as an example, and revealed the temporal and spatial distribution about the coupling sys- tematically : ( 1 ) from the perspective of time evolution, economic subsystem maintained an exponential growth rate, and the whole area moved at a high speed;resources subsystem revealed obvious fluctuation, and increased first, then dropped down after the increase with an inverted "S" shape. The whole resources subsystem can be divided into "slow rise" ," rapid de- cline" and "rapid uplift" ;the environment subsystem developed rapidly with an exponential law as a whole;except for a cer- tain degree of decline in 1999 ,the whole environment subsystem enjoyed the sound development. (2) from the perspective of spatial differentiation,the economic subsystem of the inter- city was significantly different, forming the three level circle structures with Wuhan as its center. Because of the differences in economic development,resources and environment condi- tions, historical basis, and policy mechanisms, the way of economic development had a great influence on the resources and environment subsystem, showing a development trend of the three groups. And Wuhan Metropolitan Area was divided into four tendencies : good resources and environment - promising economic, good resource environment - lagging economy, poor resource and environment - promising economic, poor resource and environment - lagging economic.
