【摘要】：在我国城镇化的背景之下,土地资源的供求矛盾十分突出,土地资源的稀缺和粗放利用已经成为制约城镇化发展的重要问题。伴随着城镇化的快速发展,辽宁省的土地资源也呈现出供给不足的状态,粗放式的土地资源利用方式导致土地利用效率低下,因此,必须对土地资源进行合理规划,在优化土地利用结构的基础之上,推动城镇化的健康发展,实现国民经济的又好又快发展。本文以辽宁省的土地利用结构为研究对象,分析了1996-2009年辽宁省土地利用结构的时空变化特征,揭示了土地利用结构变化的一些基本规律,并在此基础上分析了土地利用结构变化的驱动机制,为未来土地利用结构变化预测和土地利用结构优化提供了参考依据,进而实现土地资源的科学利用与合理配置。本文以定量分析为主,首先运用系统动力学方法,利用VENSIM软件构建了辽宁省土地利用结构仿真模型,对模型进行了历史检验和敏感性分析。然后在此基础之上运用多目标规划方法,以经济效益、生态效益和社会效益为主要目标,利用MATLAB软件预测了辽宁省未来土地利用结构的变化状况,设计了辽宁省土地利用结构优化方案。最后明确了辽宁省土地利用结构优化路径,并在此基础之上提出了辽宁省土地利用结构优化的相关政策建议。
[Abstract]:Under the background of urbanization in our country, the contradiction between supply and demand of land resources is very prominent. The scarcity and extensive utilization of land resources have become an important problem restricting the development of urbanization, along with the rapid development of urbanization. Liaoning Province's land resources also show a lack of supply, extensive use of land resources led to low efficiency of land use, therefore, we must make rational planning of land resources. On the basis of optimizing the structure of land use, we can promote the healthy development of urbanization and realize the sound and rapid development of the national economy. This paper takes the structure of land use in Liaoning Province as the research object. The temporal and spatial characteristics of land use structure in Liaoning Province from 1996 to 2009 are analyzed, and some basic laws of land use structure change are revealed. On this basis, the driving mechanism of land use structure change is analyzed, which provides a reference for the prediction of land use structure change and the optimization of land use structure. In order to realize the scientific utilization and rational allocation of land resources, this paper mainly focuses on quantitative analysis. Firstly, the simulation model of land use structure in Liaoning Province is constructed by using system dynamics method and VENSIM software. On the basis of the analysis of the history and sensitivity of the model, the multi-objective programming method is used, with the economic, ecological and social benefits as the main objectives. Using MATLAB software to predict the future changes of land use structure in Liaoning Province, designed the optimization plan of land use structure in Liaoning Province, and finally defined the path of land use structure optimization in Liaoning Province. On this basis, the paper puts forward some policy suggestions on optimizing land use structure in Liaoning Province.
