【摘要】：土地资源是城市发展的基础。城市的建设、社会的发展以及人类几乎所有的生活生产活动都需要依托土地资源才能进行。稀缺性是土地资源的基本属性,但随着我国社会的进步和GDP等各项经济指标的稳步提升,人们对土地资源的需求越来越大,这使土地资源的稀缺性更加显著。对我国而言,正面临着粮食安全和土地资源紧缺的双重考验。能否合理有效地利用城市土地资源助推经济发展和城市建设,是当下面临的重要问题。因此,城市土地集约利用研究尤为重要。四川省作为全国的资源大省、人口大省和经济大省,在国家实施西部大开发的战略中,有着举足轻重的地位。研究四川省城市的土地集约利用水平及影响因素,不仅有利于摸清城市土地利用现状、了解发展趋势及影响因素,而且有利于西部大开发战略的实施。本文站在宏观的角度,基于区位理论和可持续发展理论,运用因子分析法、分层聚类法和秩相关系数法等方法,对2004~2013年四川省城市土地进行集约利用水平进行评价并分析变化规律及影响因素。研究结果表明:(1)2004~2013年四川省18个地级市城市土地集约利用水平呈现波动式上升的态势。具体可以分为三个阶段:2004~2007年为第一阶段,是全省土地集约利用水平稳步提高阶段;2008~2010年为第二阶段,是全省土地集约利用水平迅速提高阶段;2011~2013年为第三阶段,是全省土地集约利用水平回落阶段。(2)四川省城市土地集约利用水平聚类分析结果为:第一类为巴中市;第二类为资阳市、眉山市、达州市和广安市;第三类为德阳市、乐山市、宜宾市、内江市、绵阳市、雅安市、泸州市、南充市、广元市、自贡市和遂宁市;第四类是成都市和攀枝花市。(3)2004~2013年四川省18个地级市土地集约利用水平变动浮动如下:第一,有显著提高的城市有成都、攀枝花、广元、遂宁、眉山、广安、德阳、绵阳、巴中、资阳、内江、乐山,共12个地级市,占评价总数的66.7%。其中,巴中市提高幅度最大;第二,提高不显著的城市有宜宾、雅安、泸州、南充,共4个城市,占评价总数的22%;第三,土地集约利用水平有不显著降低的城市有自贡和达州,共2个城市,占评价总数的11%。(4)影响四川省城市土地集约利用水平的因素有人均建设用地面积、人均绿地面积、城市人口密度、地均从业人数、地均社会消费品零售总额、地均固定资产投资额、城市地均GDP。其中,人均建设用地面积、人均绿地面积、城市人口密度、地均从业人数与城市土地集约利用水平为高度相关;地均社消零售额、地均固资投资额和城市地均GDP与城市土地集约利用水平为中度相关。
[Abstract]:Land resources are the basis of urban development. Urban construction, social development and almost all human life and production activities rely on land resources to carry out. Scarcity is the basic attribute of land resources, but with the progress of our society and the steady improvement of economic indicators such as GDP, the demand for land resources is increasing, which makes the scarcity of land resources more significant. To our country, is facing the double test of food security and land resource shortage. It is an important problem to use urban land resources reasonably and effectively to promote economic development and urban construction. Therefore, the study of intensive use of urban land is particularly important. Sichuan Province, as a province with large resources, large population and large economy, plays an important role in the strategy of western development. The study of the level and influencing factors of urban land intensive utilization in Sichuan Province is not only helpful to understand the present situation of urban land use and to understand the development trend and influencing factors, but also conducive to the implementation of the strategy of developing the western region. Based on the location theory and sustainable development theory, this paper uses factor analysis, hierarchical clustering and rank correlation coefficient method, etc. This paper evaluates the intensive utilization of urban land in Sichuan Province from 2004 to 2013 and analyzes the law of change and the influencing factors. The results show that: (1) from 2004 to 2013, the level of intensive land use in 18 prefectural cities in Sichuan Province showed an increasing trend of fluctuation. It can be divided into three stages: the first stage is from 2004 to 2007, the second stage is from 2008 to 2010, and the third stage is from 2011 to 2013. The results of cluster analysis of intensive land use level in Sichuan Province are as follows: the first category is Bazhong City; the second category is Ziyang City, Meishan City, Dazhou City and Guangan City; the third is Deyang City, Leshan City, Yibin City, Neijiang City, Mianyang City, Ya'an City, Luzhou City, Nanchong City, Guangyuan City, Zigong City and Suining City; the fourth category is Chengdu City and Panzhihua City. (3) the changes of land intensive utilization levels in 18 prefecture-level cities in Sichuan Province from 2004 to 2013 are as follows: first, There are 12 prefecture-level cities including Chengdu, Panzhihua, Guangyuan, Suining, Meishan, Guang'an, Deyang, Mianyang, Bazhong, Ziyang, Neijiang and Leshan, accounting for 66.7% of the total evaluation. Among them, Bazhong City has the largest increase; second, the cities with less significant improvement are Yibin, Ya'an, Luzhou, Nanchong, a total of 4 cities, accounting for 22 aspects of the total evaluation; third, the cities with no significant decrease in the level of intensive land use are Zigong and Dazhou. There are two cities, accounting for 11% of the total evaluation. (4) the factors affecting the intensive use of urban land in Sichuan Province are per capita construction land area, per capita green space area, urban population density, the number of people employed in the land, and the total retail sales of consumer goods. Land per capita fixed asset investment, urban average GDP. Among them, per capita construction land area, per capita green space area, urban population density, average number of employees and the level of intensive use of urban land are highly correlated. The average fixed capital investment and GDP of urban land are moderately correlated with the intensive use of urban land.
