摘要:
在城市空間快速增長背景下,開展城市空間增長效應(yīng)評價研究,有助于解決城市空間增長中出現(xiàn)的問題,可為確定城市空間發(fā)展戰(zhàn)略、制定空間發(fā)展政策提供依據(jù)。城市空間增長效應(yīng)評價方法旨在定量、客觀地判斷城市空間增長過程中要素配置與運(yùn)行是否合理、高效和公平。筆者建立了結(jié)構(gòu)配置效應(yīng)、經(jīng)濟(jì)配置效應(yīng)和公平配置效應(yīng)3個方面的評價體系,通過目標(biāo)法對城市空間增長效應(yīng)進(jìn)行評價,得出空間增長效應(yīng)評價函數(shù)。以重慶市為例進(jìn)行實(shí)證分析,結(jié)果顯示:重慶市2004—2013年間的城市空間增長效應(yīng)總體呈上升發(fā)展趨勢,結(jié)構(gòu)性、公平性趨好;合理配置效應(yīng)和經(jīng)濟(jì)配置效應(yīng)波動顯著,反映出城市建設(shè)面臨的用地結(jié)構(gòu)優(yōu)化、用地效率提升等方面的問題。

Abstract:
In the background of the rapid growth of urban space, it is helpful to carry out the study of urban spatial growth performance to solve the problem of urban spatial growth. This study provided basis of determining the development strategy of urban space and formulating spatial policy. Evaluation methodology of urban spatial growth effect is the way to judging the element configuration and the operation of elements is reasonable, efficient and fair during the process of urban growth space. Three evaluation systems are established in this paper, there are structure effect, economic effect and fair allocation effect. Evaluation of urban spatial growth effects by objective law will get space growth effect evaluation function. An empirical analysis of Chongqing city as an example we can get these results: the urban spatial growth effect of Chongqing from 2004 to 2013 is on the rise, structure and fairness is also on the rise; the reasonable allocation effect and the economic allocation effect are significant. These results reflect the urban construction land use structure optimization, land use efficiency and other aspects of the problem.

自20世紀(jì)90年代以來,中國城鎮(zhèn)化平均以每年1%的速度和1 300萬人次的規(guī)模向城鎮(zhèn)聚集,成為21世紀(jì)人類社會最具影響力最顯著的事件之一[1]。快速城鎮(zhèn)化進(jìn)程中,產(chǎn)業(yè)發(fā)展、基礎(chǔ)設(shè)施建設(shè)推動了城市空間的快速增長:一方面,城市面貌和基礎(chǔ)設(shè)施的改善日新月異;另一方面,城市空間增長過程中也出現(xiàn)土地利用粗放、環(huán)境污染嚴(yán)重、資源約束凸顯等問題[23],使城市空間增長的研究成為當(dāng)前中國城市建設(shè)過程中最重要的科學(xué)問題之一。在城市空間增長的研究中,如何評價城市空間增長效應(yīng),關(guān)乎國家經(jīng)濟(jì)社會可持續(xù)發(fā)展,是確定城市空間發(fā)展戰(zhàn)略、制定空間政策的依據(jù)之一。……
