【摘要】：现阶段我国处在城市化的高速发展时期,为了发展城市建设,繁荣经济,城与乡热衷于搞建设,促发展,建设用地规模不断扩大。建设用地占用农用地等现象频发,耕地资源短缺,人均耕地面积不断减少,建设用地大量扩张与耕地资源短缺的矛盾日益突出。由于不可再生资源的自然供给量是有限的,土地资源的自然供给量是严格限制的,这加剧了土地供给矛盾。伴随着城镇化进程加快,一些城市出现无序扩张,低效、粗放的土地利用现象,造成农用地资源的损耗,土地资源利用低效,土地结构不合理性等。因此,提高城乡建设用地的利用效率,最大限度的控制新增建设用地供给,大力发展建设用地节约集约利用,是我国实现严格保护耕地,确保城市繁荣发展,保障国家粮食安全的重要举措。本文以山西省河津市为研究对象,在2005-2012年土地利用现状图,河津市行政区划图,社会经济统计资料的基础上,从时间和空间角度研究分析河津市建设用地扩张的特点,运用定量与定性综合分析方法,对影响河津市建设用地扩展的影响因素进行相关性分析。最后根据时空演变特征及影响因素提出促进河津市建设用地合理性扩展的对策建议。本文研究的结论如下：(1)河津市建设用地时间演变特征分析：河津市建设用地扩展速度呈减弱趋势,有明显的阶段性,2005-2009年均扩展速率1.7%,2009-2012年年均扩展速率0.62%。结构上,农村居民点比重大。合理性分析,人口弹性指数,2005-2009年为3.15,表现出城镇建设用地扩展过快,超过了人口增长建设用地的需求量。2009-2012年人口弹性指数为0.76,此阶段接近合理系数;经济弹性指数,研究时段内始终小于1,且呈现递减趋势,说明河津市建设用地集约利用程度较高,且不断完善,说明研究区域内建设用地的集聚性规模和利用效率不断提高。(2)河津市建设用地空间演变特征分析：首先,建设用地密度分析情况,河津市城区和周边乡镇建设用地密度分异在时间段和密度分级上演变规律基本一致,均表现为低密度区大幅减少,高密度区显著增加,说明河津市建设用地规模逐步向集聚规模发展。其次,建设用地扩展强度分析情况：在2005-2009年建设用地扩展迅速,2009-2012年扩展缓慢。建设用地扩展速度各区域分级情况来看,高速扩展区域主要集中于城区,2011年后高速扩展区进入僧楼镇。最后,从圈层角度分析建设用地扩展强度与距城区中心点距离的关系,得出河津市建设用地扩展规律呈现“距离中心城区越远,建设用地空间扩展强度越弱”。(3)河津市建设用地扩展影响因素分析：城市发展的规划与政策在建设用地空间扩展过程中发挥了显著的指导作用,是河津市建设用地扩张的基准;河津市的第二产业是社会经济因素中的支柱产业,支柱产业和政府的固定资产投资是导致河津市建设用地空间扩展的根本的驱动力;社会经济因素中的居民生活水平是建设用地空间扩展的后续动力；河津市城市建设围绕交通干线布局构建基本发展框架,即交通组织作为一个重要的牵引力来指导城镇用地空间延伸;自然地理环境制约河津市建设用地的布局和发展。(4)河津市建设用地合理利用的对策建议：针对河津市的实际情况,结合影响河津市建设用地扩展的因素分析,分别从统筹城乡土地有效配置、促进产业结构调整、深化管理体制改革三方面提出促进河津市建设用地合理布局的对策建议,以期能达到社会、经济、生态环境三者的可持续发展。
[Abstract]:At the present stage of our country in a period of rapid development of the city, for the development of city construction, the economic prosperity of the city and township, keen to engage in construction, promote development, expanding the scale of construction land. Construction land occupation of agricultural land frequent phenomenon, shortage of arable land resources, per capita arable land area decreased continuously, a lot of construction land expansion contradiction with the shortage of arable land resources have become increasingly prominent. As a result of non renewable resources of the natural supply of land resources is limited, the natural supply is restricted, which exacerbated the contradiction of land supply. With the accelerating process of Urbanization, some city sprawl, inefficient phenomenon, extensive land use, resulting in loss of agricultural land resources the inefficient use of land resources, land structure is not reasonable. Therefore, to improve the land use efficiency of urban and rural construction land for the construction of new control to maximize the development of construction Land intensive utilization is to achieve the strict protection of cultivated land in China, to ensure the prosperity and development of the city, an important measure to ensure national food security. This paper takes Shanxi city of Hejin Province as the research object, in the 2005-2012 years of current land use map of Hejin city administrative zoning map based social economic statistical data, from the perspective of time and space study on the analysis of the characteristics of construction land expansion in Hejin, the use of quantitative and qualitative comprehensive analysis method, analyze the influence factors of land expansion in Hejin city construction. According to the temporal and spatial evolution characteristics and influencing factors put forward countermeasures and suggestions for reasonable extension of the construction of Hejin city. The conclusions of this study are as follows: (1) analysis of the characteristics of land construction in Hejin City: the time evolution speed decreasing trend of construction land expansion in Hejin City, has obvious stages, 2005-2009 annual growth rate of 1.7%, 2009-20 12 years the average annual growth rate of 0.62%., rural residents than the major. Rationality analysis, population elasticity index, 2005-2009 3.15, show the urban construction land expansion too fast, more than the population growth in demand for construction.2009-2012 the population elasticity index was 0.76, the reasonable coefficient; economic elasticity index during the study period, is always less than 1, and showed a decreasing trend, indicating the construction with higher degree of land intensive use in Hejin City, and continue to improve, with the agglomeration scale and continuously improve the utilization efficiency of construction in the study area. (2) analysis of the characteristics of land use spatial evolution of Hejin city construction: first, the situation analysis the density of the construction of Hejin city and the surrounding towns construction land density difference in the time period and the density classification evolution is consistent, showed low density area significantly reduced, high density area increased significantly, That Hejin city construction land scale gradually to the agglomeration scale of development. Secondly, the construction land expansion intensity analysis: in the 2005-2009 years of construction land expansion, 2009-2012 years. The slow expansion of construction land expansion speed of the regional classification situation, high growth areas are mainly concentrated in urban areas, in 2011 after the rapid expansion into the area of monk building the town land expansion. Finally, the relationship between intensity and distance from the city center of construction from the circle angle, draw the law presents "the farther distance from the city centre construction land expansion in Hejin City, the construction land expansion intensity is weak." (3) analysis of the influencing factors of construction land expansion in Hejin City: planning and the policy of city development plays a significant guiding role in construction land expansion in the process of construction land expansion of Hejin's benchmark; Hejin second industry is the social economic factors. Pillar industry, pillar industry and government investment in fixed assets is the fundamental driving force in Hejin city construction land expansion; social and economic factors in the living standards of residents is the follow-up power expansion land space construction; urban construction of Hejin city traffic around the construction layout of the basic framework of development, namely traffic organization as a the traction force to guide the urban extension space; natural geographical environment restricts the construction of Hejin city with the layout and development. (4) suggested countermeasures for the construction of the rational use of land in Hejin City: according to the actual situation of Hejin City, analysis the influence factors of land expansion in Hejin city on the construction, respectively from the urban and rural the effective allocation of land, promote the adjustment of industrial structure, the paper puts forward some suggestions for the reasonable layout and construction in Hejin city in three aspects of deepening the reform of management system, in order to achieve social, economic, health The sustainable development of the three people in the state environment.
