【摘要】：我国城市化进程面对的最大挑战就是土地利用问题。伴随着经济发展和科技进步,城市化水平不断提高,同时土地利用也发生着翻天覆地的变化,更多农业用地被征用,土地需求和土地供给之间的矛盾越发尖锐,这已经限制了城市进一步发展。只有改变城市外延扩展的发展方式,合理利用土地,才能保证城市可持续发展。所以,本文研究的是北京城市化过程中土地利用变化,这具有很强的研究价值和指导意义。本论文以北京市为研究对象,讨了北京城市化过程中土地利用的现状及其利用特点。运用相关分析和增量分析方法,对北京城市化水平与土地利用变化之间的关系、城市化水平对土地利用的影响及其程度进行了分析,从而可以清晰的了解土地利用存在的问题,并针对这些问题提出了相关建议。本文的主要分析及观点如下:在北京城市化过程中,北京市交通用地和城镇村及工矿用地每年以8.089%和1.29%的速度增长,耕地年均减少率为0.73%。这说明每年都会有大量的农用地被建设用地征用。城市建设与耕地保护是人们需要面对的重要问题。城市发展和土地利用集约化之间是相互促进的关系。2004年—2013年北京市土地利用程度综合指数区间在(300,400),从数据上可以看出北京的土地利用集约度已经很高,但要充分发挥土地利用的潜力,还应在城市化进程中注重走内涵发展的道路。城市化水平与土地利用变化显著相关。使用EXCEL数据分析工具,对北京市城市化水平和土地利用现状的分析,发现两者是显著相关,说明城市化水平是影响土地利用的主要因素。所以,在城市化过程中应该优化配置各种土地资源,保证城市化水平不断深化与土地的可持续利用。目前,北京处在高度城市化阶段,中心城区的城市化水平已经很高,城市以外延方式不断向郊区扩张,土地潜力没有得到充分利用;并且在城市发展的过程中,人们更关注短期利益,忽视长远利益。重经济轻生态的结果只能是付出更大的代价来解决城市发展过程中带来的环境问题。所以,在以后城市化过程中要加强农用地占用的审批制度,落实耕地保护政策,合理构建城市生态系统,提高人们居住环境,实现土地的节约集约利用,保证城市化与经济可持续发展。
[Abstract]:With the development of economy and the progress of science and technology, the level of urbanization has been improved, and the land use has changed dramatically, and more agricultural land has been requisitioned. The contradiction between land demand and land supply is becoming more and more acute, which has restricted the further development of the city. Only by changing the mode of development of urban extension and expanding and using land rationally can the sustainable development of the city be ensured. This paper studies the change of land use in the process of urbanization in Beijing, which has strong research value and guiding significance. This paper discusses the present situation and characteristics of land use in the process of urbanization in Beijing. By means of correlation analysis and incremental analysis, the relationship between the level of urbanization and land use change in Beijing is discussed. The impact of urbanization on land use and its extent are analyzed, so that the problems of land use can be clearly understood. The main analysis and viewpoints of this paper are as follows: in the process of urbanization in Beijing, the traffic land, urban village and industrial and mining land in Beijing are increasing at the rate of 8.089% and 1.29% per year. The average annual reduction rate of cultivated land is 0.73. This shows that a large number of agricultural land is requisitioned every year. Urban construction and cultivated land protection are important problems that people need to face. From 2004 to 2013, the comprehensive index range of Beijing's land use degree is in the range of 300 to 400. From the data, we can see that the intensity of land use in Beijing is already very high. However, in order to give full play to the potential of land use, we should also pay attention to the road of connotation development in the process of urbanization. The level of urbanization is significantly related to land use change. EXCEL data analysis tool is used. Based on the analysis of the urbanization level and the present situation of land use in Beijing, it is found that the urbanization level is the main factor affecting the land use, and the urbanization level is the main factor affecting the land use. Therefore, the allocation of various land resources should be optimized in the process of urbanization. At present, Beijing is in a highly urbanized stage, the level of urbanization in the central urban area is already very high, and the city continues to expand to the suburbs in the form of extension. The potential of land is not fully utilized; and in the process of urban development, there is a greater focus on short-term benefits, Neglecting long-term interests. The result of emphasizing economy over ecology can only be to pay a greater price to solve the environmental problems brought about in the process of urban development. Therefore, in the future urbanization process, we should strengthen the examination and approval system for the occupation of agricultural land. The policy of cultivated land protection should be carried out, the urban ecosystem should be constructed rationally, the living environment of people should be improved, the land could be saved and utilized intensively, and urbanization and economic sustainable development could be ensured.
