【摘要】：土地作为一种不可再生资源,是人类及社会发展不可或缺的重要的物质资源。随着社会、经济的发展,土地利用结构及布局日益复杂化,同时,在土地利用过程中,由于土地利用结构不合理引起的人地矛盾、生态环境等问题日益突出。因此,如何合理利用土地,优化调整土地利用结构就成为亟需解决的问题。本文以日照市作为研究对象,对其土地利用结构的优化调整进行研究,以期为日照市的土地管理工作提供一定的理论政策支持,所选择的优化方案能够充分发挥日照市土地的综合功能,达到促进日照市社会经济可持续发展的目的。本文以区位理论、土地可持续利用理论、人地协调(关系)理论、土地规划弹性理论等理论为指导,运用一系列指标对日照市的土地利用结构变化进行分析,探寻引起其变化的驱动力,构建基于线性规划、多目标规划的土地利用结构优化模型,并对方案进行择优,找寻适合日照市土地利用的最优结构。本文的研究内容主要包括:(1)土地利用结构分析。在2003-2012年日照市土地利用变更数据的基础上,从土地利用变化幅度、速度、强度、综合度、信息熵等方面分析日照市土地利用变化情况,得出日照市土地利用的特点。(2)选取22个经济社会指标,运用SPSS16.0对其进行主成分分析,分析引起日照市土地利用变化的驱动因子。(3)优化调整日照市土地利用结构。根据日照市历年的社会经济状况,运用不同的数学方法预测日照市的社会经济发展趋势,构建基于线性规划、多目标规划的土地利用结构优化模型,分析评价优化结果并进行择优。(4)在前文分析的基础上,提出保障日照市土地利用结构优化方案实施的措施。在以上分析和模型求解的基础上,本文的研究成果如下:(1)日照市2003-2012年土地利用程度总体水平较高,土地利用处于发展时期,土地利用变化较为显著。整体看来,日照市农用地减少,园地、林地数量减少;建设用地的数量逐年增加,城镇建设用地扩张速度加快;未利用地数量减少。(2)通过运用SPSS16.0对所选取的22个经济社会指标进行主成分分析,得出引起日照市土地利用结构变化的主要驱动因子分别为:经济社会发展因素、人口因素及土地政策。(3)根据日照市社会经济的发展趋势,结合日照市土地利用及社会经济发展的特点,确定2020年日照市的土地利用结构为:耕地241884.56hm2、园地25920.53hm2、林地87595.50hm2、其他农用地61448.99hm2、居民点及工矿用地71077.19hm2、交通运输用地13405.71hm2、水利设施用地7736.02hm2、未利用地26788.90hm2。(4)保障日照市土地利用结构优化方案实施的措施主要为保护耕地和基本农田,控制建设用地规模,科学利用建设用地,积极开展土地综合整治,加强生态保护,改善生态环境。
[Abstract]:As a non-renewable resource, land is an indispensable material resource for human and social development. With the development of society and economy, the structure and layout of land use are becoming more and more complicated. At the same time, in the process of land use, the contradiction between man and land caused by unreasonable land use structure and ecological environment are becoming more and more prominent. Therefore, how to make rational use of land and optimize the structure of land use has become an urgent problem. In this paper, Rizhao City is taken as the research object to study the optimization and adjustment of its land use structure in order to provide some theoretical and policy support for the land management in Rizhao City. The optimized scheme can give full play to the comprehensive function of the land in Rizhao and achieve the purpose of promoting the sustainable development of social economy in Rizhao. Under the guidance of location theory, land sustainable use theory, human-land coordination theory and land planning elasticity theory, this paper uses a series of indicators to analyze the changes of land use structure in Rizhao City. Based on linear programming and multi-objective programming, the optimization model of land use structure is constructed, and the scheme is selected to find the optimal structure suitable for land use in Rizhao city. The main contents of this paper are as follows: (1) Analysis of land use structure. Based on the data of land use change in Rizhao City from 2003 to 2012, this paper analyzes the land use change in Rizhao City from the aspects of land use change range, speed, intensity, comprehensive degree, information entropy, etc. The characteristics of land use in Rizhao City were obtained. (2) 22 economic and social indexes were selected and principal component analysis (SPSS16.0) was used to analyze the driving factors of land use change in Rizhao City. (3) Land use structure of Rizhao City was optimized and adjusted. According to the social and economic situation of Rizhao City over the years, different mathematical methods are used to predict the social and economic development trend of Rizhao City, and a land use structure optimization model based on linear programming and multi-objective programming is constructed. Analysis and evaluation of the results of optimization and selection. (4) on the basis of the previous analysis, put forward the measures to ensure the implementation of land use structure optimization scheme in Rizhao. On the basis of the above analysis and model solution, the research results of this paper are as follows: (1) the overall level of land use in Rizhao City from 2003 to 2012 is high, the land use is in the developing period, and the land use change is more significant. As a whole, the number of agricultural land, garden land and woodland in Rizhao City is decreasing, the number of construction land is increasing year by year, and the expansion rate of urban construction land is accelerating. (2) through the principal component analysis of 22 selected economic and social indicators by using SPSS16.0, the main driving factors of the land use structure change in Rizhao are: economic and social development factors. Population factors and land policies. (3) according to the trend of social and economic development in Rizhao City, combined with the characteristics of land use and social and economic development in Rizhao City, The land use structure of Rizhao city in 2020 is as follows: cultivated land 241884.56hm2, garden land 25920.53hm2, woodland 87595.50hm2, other agricultural land 61448.99hm2, residential land and industrial and mining land 71077.19hm2, transportation land 13405.71hm2, water conservancy facility land 7736.02hm2, unused land 26788.90hm2. The measures taken to optimize the implementation of the program are mainly to protect arable land and basic farmland. We should control the scale of construction land, make scientific use of construction land, actively carry out comprehensive land renovation, strengthen ecological protection and improve ecological environment.
