【摘要】 土地资源的可持续利用是社会经济可持续发展的关键，也是社会发展永恒的主题。城乡结合部作为城市地域结构的一个重要组成部分，是农村城市化的先导地区，发展十分迅速。尤其是临近城市地带，城市因素不断增加，而乡村因素迅速衰退，形成了一个城市和乡村功能相互渗透、社会经济发展特殊而又活跃的地带，也是目前土地利用问题最多、矛盾最尖锐的地区。城市化过程中城市土地面积的增加是任何一个国家或地区的必然现象。城市的不断发展引起城乡结合部土地利用的动态变化，土地利用结构和布局的重组和替代。只要城市的发展不停止，城乡结合部土地利用的研究就具有重大的现实意义。本文以城乡结合部土地利用结构优化调控原理为切入点，以柳州市为例，首先对柳州市城乡结合部土地利用结构数量和空间变化进行全方位的研究，从土地利用速度变化、幅度变化、程度变化、土地利用结构信息熵方面分析土地利用结构数量变化特征：从土地利用结构信息熵空间分异性、洛伦茨曲线和洛伦茨系数两方面揭示空间结构变化特征。其次，在揭示该特殊区域土地利用结构变化特征的基础上，采用国内生产总值、工业生产总值、农民人均纯收入、粮食安全(耕地总面积和人均耕地面积)、农民社会保障、生态功能性用地和生态系统健康指标，分别从经济效益、社会效益、生态效益三方面对柳州市城乡结合部土地利用结构的可持续性进行分析。第三，在对城乡结合部土地利用结构系统认识的基础上，采用多目标线性规划模型对城乡结合部土地利用结构进行优化。最后，提出柳州市城乡结合部土地利用结构调控对策。更多还原

【Abstract】 The sustainable utilization of land resources not only is the key of the development of social economy, but also the eternal theme of social development. The urban-rural-integration-area is an important component part of urban area structure, also is a guide region, developing rapidly. Especially, with the increasing of urban factor and the decreasing of the rural factor, the neighboring urban belt has become a belt where the function of urban and rural interpenetrates, social economy develops specially and actively, the problem of land use is most and the contradiction is quite acuity on a global scale today. During the process of urbanization, it’s an inevitable phenomenon that the urban land area will enlarge in a country or a district. The urban unceasing development inevitably causes the dynamic change of the urban-rural- integration-area land utilization, the reorganization and the substitution of land utilization structure and layout. So long as the development of urban doesn’t stop, the research of land utilization in the urban-rural-integration-area has great practical significance.This paper takes the theory that land use structure optimization on sustainable utilization as breakthrough point, takes the city Liu-Zhou as an example. Firstly, the paper analyzes the numeral and spatial structure of land use in Liu-Zhou urban-rural-integration-area in a whole orientation view; selects such as the velocity variation of land use, the amplitude variation of land use, the change of extent of land use, and the information entropy of land use structure and so on as indexes to analyze the change of numeral structure; reveals the character of the change of spatial structure by both spatial difference of information entropy and the Lorenz’s curve and Lorenz’s coefficient. Secondly, on the basis of revealing the character of the change of land use structure in such special region, the paper takes like GDP, industrial output, peasant’s per capita net income, per capita cultivated land, ecological functional land use, ecosystem health and so on as indexes to analyze the sustainability of land use structure of Liu-Zhou urban-rural-integration-area from economic benefit, social benefit and ecological benefit. Thirdly, on the basis of realizing the land use structure system, multi-objective linear programming model was adopted to optimize the structure of the urban-rural-integration-area land use. Finally, the paper advances the countermeasures to the structure of urban-rural-integration-area regulating and controlling.更多还原
