【摘要】：土地是人类生存和社会发展的物质基础,也是承载人类生产活动的基本场所,然而,随着经济社会的不断发展、人口规模的快速壮大以及产业结构的不断升级,对土地的需求与日俱增,相比有限的资源供给量,土地供需矛盾不断被激化。与此同时,生态环境恶化、土地质量下降等问题也伴随而来,严重制约着经济、社会和生态的协调可持续发展,如何突破有限的面积约束,尽可能的发挥土地资源的最大效用,以推动经济社会的健康快速发展成为我国土地利用中亟待解决的热点问题。在这种情况下,合理的资源配置和土地结构优化,成为当前国情下缓解人地矛盾、适应城市化发展的最有效的途径。通过对当下土地资源利用方式和结构的合理调整即土地利用结构优化,对提高土地资源的利用效率实现经济、社会和生态效益的同步最优具有重要意义。本文通过构建以经济、社会和生态效益为目标函数的多目标规划模型,借助计算机等实用工具对模型进行求解并分析各个优化方案的优缺点,最终得到符合绵阳市未来发展的城市建设用地结构最优方案,为有效控制城市用地规模、划定城市增长边界以及城市总体规划等提供有效参考。主要研究结论如下：(1)对绵阳市城市土地利用结构现状及部门信息熵的分析表明,绵阳市的部门信息熵正处于减少的阶段,城市土地利用目前处于一个有序的状态。此外通过与成都、德阳等城市的土地利用结构进行分析比较,得出绵阳市的居住用地的比例和人均居住用地面积均偏低,工业用地所占的比例较高,公用设施用地与绿地和广场用地所占比重远低于全国平均水平,土地利用结构有待优化。(2)运用多元回归分析,建立绵阳市经济效益与各类用地面积的多元回归方程得出其经济效益的目标函数;通过产业部门的直接劳动报酬系数矩阵与绿色消耗矩阵求解出社会效益同生态效益的目标函数。在此基础上利用绵阳市城市建设用地结构优化的多目标规划模型,求解得到经济、社会和生态效益三个目标函数下的优化方案,对方案进行对比分析,最终得出符合规划要求并能满足绵阳市未来发展用地需求的最优方案。(3)为实现城市土地利用结构优化应采取实施产业结构优化战略,打造产业科技城；开展城市立体开发,全面优化城市土地利用结构；培育土地市场,强化土地配置的市场机制；强化土地利用规划作用,促进城市健康发展等措施。
[Abstract]:Land is the material basis of human survival and social development, but also the basic place to carry human production activities. However, with the development of economy and society, the rapid expansion of population and the upgrading of industrial structure. The demand for land is increasing day by day, compared with the limited supply of resources, the contradiction between supply and demand of land has been intensified. At the same time, the deterioration of ecological environment and the decline of land quality are accompanied by the problems, which seriously restrict the economy. The coordinated and sustainable development of society and ecology, how to break through the limited area constraints, as far as possible to give play to the maximum utility of land resources. To promote the healthy and rapid development of the economy and society has become a hot issue to be solved in land use in China. In this case, reasonable resource allocation and land structure optimization have become the current situation to alleviate the contradiction between man and land. The most effective way to adapt to the development of urbanization. Through the rational adjustment of the current land resource use mode and structure, that is, land use structure optimization, to improve the efficiency of land resources use to achieve economic. The simultaneous optimization of social and ecological benefits is of great significance. This paper constructs a multi-objective programming model with economic, social and ecological benefits as the objective function. With the help of computer and other practical tools to solve the model and analyze the advantages and disadvantages of each optimization scheme, finally get the optimal scheme of urban construction land structure in accordance with the future development of Mianyang, for the effective control of the scale of urban land use. The main conclusions are as follows: 1) the analysis of the present situation of urban land use structure and the department information entropy of Mianyang city. The department information entropy of Mianyang is in the stage of decreasing, and the urban land use is in an orderly state at present. In addition, the structure of land use in cities such as Chengdu and Deyang is analyzed and compared. It is concluded that the proportion of residential land and the per capita living area of Mianyang is low, the proportion of industrial land is higher, the proportion of public facilities land and green land and square land is far lower than the national average level. The land use structure needs to be optimized. (2) the multivariate regression equation of economic benefit and land area of Mianyang city is established, and the objective function of economic benefit is obtained. Through the direct labor reward coefficient matrix and green consumption matrix of industry department, the objective function of social benefit and ecological benefit is solved. On this basis, the multi-objective programming model of optimizing the structure of urban construction land in Mianyang City is used. . The optimization scheme under the three objective functions of economic, social and ecological benefits is obtained, and the scheme is compared and analyzed. Finally, the optimal plan, which can meet the planning requirements and meet the needs of future development land use in Mianyang City, is obtained. In order to realize the optimization of urban land use structure, the strategy of industrial structure optimization should be adopted and the industrial science and technology city should be built. To develop urban three-dimensional development and optimize the structure of urban land use in an all-round way; Cultivate the land market and strengthen the market mechanism of land allocation; Strengthen the role of land use planning, promote the healthy development of the city and other measures.
