【摘要】：城市土地是城市发展的基础和保障,是城市一切社会经济活动的载体。随着我国工业化、城镇化进程的加快,我国城市土地利用中出现了土地粗放利用、生态环境恶化等现象,致使人地矛盾更加突出,阻碍了城市的可持续发展。充分利用城市存量土地,开展城市内部挖潜,节约集约利用土地成为解决该问题的根本途径。同时,全球气候变化带来的新问题也正威胁着人类的生存与发展,人类逐步认识到只有发展低碳经济才能实现可持续发展,也更加关注土地利用对碳排放的影响。将低碳经济理念引入到城市土地集约利用评价中,符合可持续发展的客观需要,对于控制城市规模、提高土地使用效率、促进经济良性发展具有重要意义。本文在梳理国内外研究现状的基础上,系统阐述了低碳经济及土地集约利用相关的概念及内涵,将低碳经济理念引入到土地集约利用评价中,构建了反映土地利用中人地关系的PSR模型,并以郑州市为例,分析了郑州市土地利用现状中存在的问题,反映城市土地利用实行低碳集约的迫切性。在此基础上构建了PSR模型评价指标体系,对郑州市1998—2012年的土地利用状况进行评价。通过研究,本文主要的结论为:(1)郑州市历年低碳经济发展与土地集约利用水平在强脱钩与弱脱钩之间波动,低碳经济发展与土地集约利用存在着显著的正相关关系,有效的促进了土地集约利用的发展。但作为“富煤贫油少气”的郑州,低碳经济发展缓慢,导致部分年份的脱钩状态不理想。(2)郑州市土地集约利用整体有趋于低碳化、集约化的趋势。从集约状态来看,1998-2004年为粗放利用阶段,2005-2009年为较粗放利用阶段及2010-2012年处于基本集约利用阶段。但郑州市土地低碳集约利用水平相对较低,还没有达到集约利用状态,集约状态并不理想。(3)郑州市土地利用各子系统间的协调系数较低,各子系统间存在不均衡发展的状况,这也是郑州市低碳理念下土地集约利用程度较低的一个重要原因。但整体来说,郑州市土地利用各子系统间的协调度整体呈上升趋势,很好的契合了土地低碳集约利用水平变化的实际情况,与实际基本相符,能较好的反映低碳集约利用现状与集约目标之间的差距,模型具有较高的可信度。基于评价结果和结论,本文提出相关政策建议,旨在为促进郑州市城市土地利用的低碳化、集约化,实现经济的可持续发展提供理论基础。
[Abstract]:Urban land is the foundation and guarantee of urban development and the carrier of all social and economic activities.With the acceleration of industrialization and urbanization in our country, extensive use of land and deterioration of ecological environment appear in the urban land use of our country, which makes the contradiction between man and land more prominent and hinders the sustainable development of the city.The fundamental way to solve this problem is to make full use of the urban land stock, to develop the potential in the city and to economize on the intensive use of the land.At the same time, the new problems brought by global climate change are threatening the survival and development of human beings. Human beings gradually realize that only the development of low-carbon economy can achieve sustainable development, and pay more attention to the impact of land use on carbon emissions.Introducing the concept of low-carbon economy into the evaluation of intensive utilization of urban land meets the objective needs of sustainable development. It is of great significance to control the scale of the city, improve the efficiency of land use and promote the benign development of the economy.On the basis of combing the current research situation at home and abroad, this paper systematically expounds the concept and connotation of low carbon economy and intensive land use, and introduces the concept of low carbon economy into the evaluation of land intensive utilization.This paper constructs a PSR model to reflect the relationship between man and land in land use, and takes Zhengzhou as an example, analyzes the problems existing in the present situation of land use in Zhengzhou, and reflects the urgency of implementing low carbon intensity in urban land use.On this basis, the evaluation index system of PSR model is constructed to evaluate the land use in Zhengzhou from 1998 to 2012.The main conclusion of this paper is: (1) the low carbon economy development and land use level fluctuate between strong decoupling and weak decoupling, and there is a significant positive correlation between low carbon economy development and land intensive utilization.Effectively promote the development of intensive land use.But as "rich in coal, lean oil and little gas", the development of low-carbon economy is slow, which leads to the unideal state of decoupling in some years.) the whole intensive utilization of land in Zhengzhou City tends to be low carbonized and intensive.From the point of view of the intensive state, the period 1998-2004 is the stage of extensive utilization and the period of 2005-2009 is the stage of extensive utilization, and the period of 2010-2012 is in the stage of basic intensive utilization.However, the level of low carbon intensive utilization of land in Zhengzhou is relatively low, which has not reached the state of intensive utilization, and the intensive state is not ideal. 3) the coordination coefficient among the subsystems of land use in Zhengzhou is relatively low, and there is a situation of unbalanced development among the subsystems.This is also a low-carbon concept of Zhengzhou land intensive use of an important reason.But on the whole, the degree of coordination among the subsystems of land use in Zhengzhou City is on the rise, which is in good agreement with the actual situation of the change of land low carbon intensive utilization level, and is basically in line with the actual situation.It can well reflect the gap between the current situation of low carbon intensive utilization and the intensive goal, and the model has high credibility.Based on the evaluation results and conclusions, this paper puts forward some relevant policy suggestions, aiming at providing a theoretical basis for the promotion of low carbonization and intensification of urban land use in Zhengzhou and the realization of sustainable economic development.
