【摘要】 土地是一种不可再生资源,是人类赖以生存、社会赖以发展的物质基础。随着经济的发展,社会工业化、城镇化的加速发展,人口数量的增加,人地矛盾日益突出,并由此引致了一系列的资源和环境问题,这些大都与土地利用结构不当有关。如何合理的利用有限的土地资源,制定科学的土地利用结构优化的方案,调整土地利用的思路,解决人地之间的矛盾,已成为城市可持续发展亟待解决的问题。研究土地利用结构优化不仅具有理论意义还具有很重要的现实意义。本文以三门峡市为研究区域,以2006年为基期年,运用灰色线性规划和BP人工神经网络方法对三门峡市土地利用结构进行了优化配置研究。其主要内容包括:(1)全面论述了土地利用结构优化的基本理论和技术手段,为三门峡市土地利用结构优化提供了理论基础;(2)从地理区位、自然条件和社会经济条件三方面较为详细的分析了三门峡市土地利用的外部环境,并从土地利用类型的数量结构、空间结构和组合结构三个方面,对三门峡市土地利用现状进行了定量分析和评价,为土地利用结构优化提供了现实基础;(3)依据三门峡市历年来的数据,应用GM(1,1)灰色预测模型,对三门峡市2015年的人口、耕地、粮食产量、粮食单产进行预测;(4)建立灰色线性规划模型,对三门峡市土地利用结构进行优化,应用灰色线性规划程序计算,最终构造出3个供选方案;(5)构建BP人工神经网络模型对供选方案进行择优,最后得出三门峡市土地利用结构优化的最优方案,同时,为有效的实施该方案提出了相应的保障措施。更多还原

【Abstract】 Land is a kind of non-renewable resources, which is the material base of mankind existence and society development. With the increasing of population, rapid development of urbanization and economic construction, the contradiction between the expanding population and the reducing land resource become more and more evident and has resulted in a lot of problems involving resource and environment because of making no good use of the land use structure. How to make use of the limited land resource reasonably and to adjust the land use structure in order to solve the contradiction between the people and land need to be solved urgently. Therefore, the research on the land use structure optimization is significant in theory and practice.This paper regards the city of Sanmenxia as studying area, 2006 as annual base period. The methods of grey linear programming and the artificial neural network are applied to the research on the land use structure optimization in Sanmenxia. Main contents are including: (1) Based on the discussion of principles and methods of the land use structure optimization, the theoretical foundation for the the land use structure optimization in Sanmenxia is provided. (2) In this paper, we analyze the land use conditions of the city of Sanmenxia from three aspects of the geographical position, natural foundation and social economic environment, and quantitatively analyze and evaluate the current land use situation from three aspects including the combined, spatial and quantity structure of the land use characteristics, which provides the realistic foundation for optimizing land use in Sanmenxia. (3) The population, cultivated land, grain total amount and per unit area yield to 2015 are predicted in Sanmenxia according to the city’s data over the past years by applying the grey predicting model of GM(1,1). (4) The grey linear programming model (GLP) is established to optimize the land use structure in Sanmenxia. It is calculated by applying the grey linear programming and final1y we get three optional schemes to be selected. (5) A evaluation model of the land use structure optimization is established by BP neural network and the optimum scheme of land use structure of Sanmenxia is obtained. In addition, the thesis provided some measures and suggestions to realize the scheme.更多还原
