| 摘 要： | 构建脱钩状态模型和响应程度模型,通过定量研究1995~2010年长春市城市拓展对资源消耗的影响程度,得到以下结论:①长春市城市拓展与资源消耗总体呈现"双增长"特征,城市快速拓展导致的资源消耗及资源环境压力不断增大;②长春市城市拓展与资源消耗始终处于"相对脱钩"状态,且资源消耗增长速度随着城市拓展呈先相对下降、后又相对提升的趋势。在城市拓展规模保持总体稳定增长的情况下,资源消耗变化是影响二者脱钩状态与脱钩程度演化的关键因素;③随着长春市城市拓展规模的不断扩大,其对资源消耗增长的影响程度持续增大,进一步说明城市拓展作为资源消耗的驱动力,其变化是导致长春市城市拓展对资源消耗影响程度增大的重要推动因素。

| Abstract: | The rapid development of cities will inevitably lead to mass consumption of recourses,so the city development will face the problem of the severe resources and environmental pressure.With the rapid progress of urbanization in China,the social economic behaviors,like the rapid urban expansion,population agglomeration,economic growth,built-up land increase and so on,are accelerating.Those bring the mass use and excessive consumption of resources such as cultivated land,water,energy and other natural resources.Under the restriction of resources,vulnerability problems during the urban development become more serious.Therefore,it seems more important and urgent to carry out the research on the impact of urbanization and urban expansion to resources and environment in China.Urbanization and urban expansion interaction with resources and environment is always the hot issue in academia,and there have been many great achievements at present.But it is still need to further explore and discuss the quantitative measurement of the effect of urban expansion to resources consumption.The quantitative research of the influence of urban expansion on the resources consumption are done employing the decoupling state model and response degree model,based on the statistic data of Changchun in 1995-2010.The following conclusions are drawn: 1) both the urban expansion and resources consumption shows the fluctuant double growth trend,including the scale and the growth rate.That means the resources consumption and the pressure of the resources and environment keep increasing.2) The urban expansion and resources consumption of Changchun is in a relatively decoupling state.With the rapid expansion of urban,the growth trend of resources consumption shows first a relative decline and then a growth trend.Under the circumstance of the urban expansion scale keeps stable growth in Changchun,the resources consumption is the key factor to affect both the decoupling state and the change degree of decoupling.3) The main driving force of the resources consumption enlarging is the rapid urban expansion in Changchun which is increasing continuously.Being the driving power,urban expansion is also the most important driving factor that led to the growth of influence degree of the urban expansion on the resources consumption.In this article,the applicability of the decoupling state model and response degree model are explored and the interaction between urban expansion and resources consumption is analyzed.Meanwhile,the impact feature and trend of rapid urban expansion to resources consumption of Changchun City is revealed,which could provide a reference and theory basis of making the targeted sustainable development strategy. |
