【摘要】：开展土地利用空间冲突研究,对于解决土地利用、景观变化、产业布局优化等问题具有重要的作用。目前学术界通过研究土地利用空间冲突来优化土地利用结构的研究还很欠缺。本研究以甘肃省秦州区为例,基于Arcgis10.2软件的空间分析功能,构建土地利用空间冲突模型,分析秦州区时间和空间上土地利用冲突变化特征,提出土地利用优化配置方案,实现土地资源可持续利用目标,以期为研究区土地资源优化布局提供重要参考。结果表明:(1)研究期内建设用地扩张迅速,面积增加的主要来源是对农用地的挤占。耕地面积虽然未减反增,主要是因为秦州区通过实施土地整治项目来补充耕地的数量,以此来保证耕地总量不减。(2)在研究阶段内,从时间上看,秦州区稳定可控的个数由2009年的411个减少到2015年的314个,基本可控的个数由2009年的4479个减少到2015年的4461个,轻度冲突的个数由2009年的3771个增加到2015年的3846个,中度冲突的个数由2009年的1123个增加到2015年的1149个,重度冲突的个数由2009年的119个增加到2015年的133个,秦州区土地利用空间冲突类型在基本可控和轻度冲突,目前冲突处在显现阶段。从空间上看,各土地利用类型在不同冲突类型上的表现也略有不同。城镇工矿用地、其他土地、水域及水利设施用地和园地的冲突主要表现在重度冲突;林地和交通用地主要表现在稳定可控和基本可控;耕地主要表现在轻度冲突;草地主要表现在中度冲突。冲突分布由城区中心向四周扩散。呈这种冲突的原因是秦州区社会经济发展较快,政府不断完善城市基础设施建设,改善城乡居民生活环境,开展的这些社会经济活动对区域生态安全造成了一定的威胁,使得区域内的土地利用空间冲突较高。(3)通过分析不同等级内主导土地利用类型和存在的问题,划分出10个土地利用功能亚区,其中,林果种植保育亚区、生态农业后备亚区、生态涵养亚区、湿地廊道保育亚区和生态农业种植亚区属于可控级别,现代农业发展亚区、城乡发展协调亚区、生态环境脆弱亚区、城镇优化建设亚区和风景旅游名胜建设亚区属于失控级别,对分区结果进行有效性分析,证明分区符合土地利用总体规划的用地安排,最后从三方面提出建议,优化土地利用空间结构,缓解区域冲突程度。
[Abstract]:The study of land use spatial conflict plays an important role in solving the problems of land use, landscape change, industrial layout optimization and so on. At present, the research of optimizing land use structure by studying land use space conflict is still lacking. Taking Qinzhou District of Gansu Province as an example, based on the spatial analysis function of Arcgis10.2 software, the spatial conflict model of land use is constructed, and the change characteristics of land use conflict in time and space in Qinzhou district are analyzed, and the optimal allocation scheme of land use is put forward. The goal of sustainable utilization of land resources can be realized in order to provide an important reference for optimizing the distribution of land resources in the study area. The results showed that the construction land expanded rapidly during the period of study, and the main source of the increase in area was the crowding of agricultural land. Although the area of cultivated land has not decreased but has increased, it is mainly because Qinzhou District replenishes the amount of cultivated land through the implementation of land renovation projects to ensure that the total amount of cultivated land will not be reduced. The number of stable and controllable cases in Qinzhou decreased from 411 in 2009 to 314 in 2015, the number of basic controllable decreased from 4479 in 2009 to 4461 in 2015, and the number of mild conflicts increased from 3771 in 2009 to 3,846 in 2015. The number of moderate conflicts increased from 1123 in 2009 to 1149 in 2015, and the number of severe conflicts increased from 119 in 2009 to 133 in 2015. The conflict is at this stage. From the spatial point of view, the different land use types in different conflict types are also slightly different. The conflicts between urban industrial and mining land, other land, water resources and water conservancy facilities and garden land are mainly manifested in severe conflict, woodland and traffic land are mainly stable and controllable, arable land is mainly in mild conflict. Grassland is mainly manifested in moderate conflict. The conflict spread from the center of the city to the surrounding area. The reason for this conflict is that the social and economic development of Qinzhou District is relatively fast, the government has continuously improved the urban infrastructure construction, improved the living environment of urban and rural residents, and these social and economic activities have posed a certain threat to the regional ecological security. By analyzing the dominant land use types and existing problems in different levels, we can divide 10 land use functional subareas, among which, forest and fruit planting and conservation subareas, ecological agriculture reserve subareas, are divided into 10 subareas, including forest and fruit planting and conservation subareas, ecological agriculture reserve subareas, forest and fruit planting and conservation subareas, and ecological agriculture reserve subareas. Ecological conservation subareas, wetland corridor conservation subareas and eco-agricultural planting subareas belong to controllable levels, modern agricultural development subareas, urban and rural development coordination subareas, ecological environment fragile subareas, The optimized construction sub-area of town and the sub-area of scenic spot construction belong to the out-of-control level. This paper analyzes the validity of the zoning results, proves that the zoning accords with the land use arrangement of the overall land use planning, and finally puts forward some suggestions from three aspects. Optimize the spatial structure of land use and alleviate the degree of regional conflict.
