【摘要】：土地资源是最基础的资源,是人类生存和发展的物质基础,也是经济社会最基本的保障。兰州新区是一座建立在秦王川传统农业区的新型城市,在面对自然环境恶劣、生态破坏严重等客观问题时,如何协调城市发展与人口、生态、经济、资源之间的关系是迫切需要解决的问题,而土地综合承载力的高低在兰州新区的发展的规模中有很重要的地位。本文以兰州新区的土地综合承载力为研究目标,从社会、生态环境、经济等方面展开对兰州新区土地综合承载力的评价。本文通过对承载力相关理论的学习,结合当地的实际情况,咨询相关专家,运用理论研究与实证分析相结合,以及对评价指标进行定量分析等方法,以评价兰州新区土地综合承载力为目标,构建出兰州新区土地综合承载力评价的指标体系。该体系包括目标层、准则层、指标层三个层次,在准则层层面上包括社会子系统、生态环保子系统、经济子系统三个子系统,每个子系统又包括经反复筛选对比后的4-5个有代表性的指标,总共选出具有代表性的13个指标。以此为基础对兰州新区在建设之前、建设初期、建设中长期等各发展阶段的土地综合承载力展开了研究评价,并进行分析。研究结果表明,兰州新区在建设之前,2012年土地综合承载力0.2968；建设初期,2013年土地综合承载力为0.2981；经过两年的建设,2014年土地综合承载力得到很大的提高,达到0.5081的中等水平；建设中期,在2020年,土地综合承载力值为0.5495,属于中等水平；在后期,2030年,土地综合承载力达到0.6913的较高承载力水平,实现了土地综合承载力由低水平向较高水平的提升。然后通过障碍因素分析得出在城市建设初期,制约城市发展的主要因素是经济因素,在中后期则是生态环保因素。最后在对兰州新区土地综合承载力做出评价的基础上,找出制约城市发展的因素,并提出提高土地综合承载力的建议和对策。及大力推进城市生态环境建设,控制人口数量和提高人口素质,切实保护耕地和带动周围农村的发展,为新区发展建立一个备用粮仓,建立节水型城市等建议。对兰州新区未来的发展具有一定的指导作用。
[Abstract]:Land resource is the most basic resource, the material basis of human existence and development, and also the most basic guarantee of economy and society. Lanzhou New area is a new type of city established in the traditional agricultural area of Qinwangchuan. In the face of objective problems such as bad natural environment and serious ecological damage, how to coordinate urban development with population, ecology, economy, etc. The relationship between resources is an urgent problem to be solved, and the comprehensive carrying capacity of land plays an important role in the scale of the development of Lanzhou New area. Taking the comprehensive carrying capacity of land in Lanzhou New area as the research objective, this paper evaluates the comprehensive carrying capacity of land in Lanzhou New area from the aspects of society, ecological environment, economy and so on. By studying the theory of bearing capacity, consulting relevant experts, combining theoretical research with empirical analysis, and quantitative analysis of evaluation index, etc., this paper studies the theory of bearing capacity, combines the actual situation of the region, consults relevant experts, and so on. In order to evaluate the comprehensive carrying capacity of land in Lanzhou New area, the evaluation index system of comprehensive carrying capacity of land in Lanzhou New area is constructed. The system consists of three levels: target layer, criterion layer and index layer. At the level of criterion level, it includes three subsystems: social subsystem, eco-environmental protection subsystem and economic sub-system. Each subsystem also includes 5 representative indexes after repeated screening and comparison, and a total of 13 representative indicators are selected. On the basis of this, the comprehensive carrying capacity of land in Lanzhou New area before construction, initial stage and medium-and long-term development stage was studied and evaluated, and the analysis was carried out. The results show that before the construction of Lanzhou New area, the comprehensive carrying capacity of land was 0.2968 in 2012 and 0.2981 in 2013, and in the initial stage of construction, the total carrying capacity of land was 0.2981 in 2013. After two years of construction, the comprehensive carrying capacity of land has been greatly improved in 2014, reaching to the medium level of 0.5081. In the middle stage of construction, in 2020, the value of comprehensive carrying capacity of land is 0.5495, which belongs to the middle level; In the later stage, in 2030, the comprehensive carrying capacity of land reached 0.6913, and the comprehensive carrying capacity of land increased from low level to high level. Then through the analysis of obstacle factors, it is concluded that in the initial stage of urban construction, the main factor restricting the development of the city is the economic factor, and in the middle and late stages it is the ecological and environmental protection factor. Finally, based on the evaluation of the comprehensive carrying capacity of land in Lanzhou New area, the factors restricting the development of the city are found out, and the suggestions and countermeasures to improve the comprehensive carrying capacity of land are put forward. And to promote the construction of urban ecological environment, to control the number of population and improve the quality of population, to protect cultivated land and promote the development of surrounding rural areas, to establish a reserve granary for the development of the new area, to establish a water-saving city, and so on. It has a certain guiding role for the future development of Lanzhou New area.
