【摘要】：土地利用多功能性研究是土地科学研究的重要内容,对推动区域可持续发展具有重要意义。该文以环京津贫困带31区县为分析单元,构建指标体系对该区2000、2014年土地利用多功能性进行综合测度,运用空间分析方法和空间计量模型分析其土地利用多功能性时空分异特征及影响因素。结果表明,1)2000、2014年环京津贫困带土地利用多功能性水平呈现西高东低、中部高南北低的空间格局。2000-2014年土地利用多功能性水平整体有所提升,空间格局变化显著,主要表现为较高水平区县向坝上高原及坝缘山区扩展,中等水平区县大幅收缩且略有东移,较低和低水平县域向市域边缘地区集中。2)2000-2014年环京津贫困带土地生产功能空间格局变化显著,主要表现为高水平区县向张家口市区及周边区域扩展,较高、中等水平区县分别呈现北移、东移态势,较低、低水平县域向市域边缘地区集中。2000-2014年土地生活功能、生态功能空间分异格局无较大变动,局部地区略有变化。3)环京津贫困带土地利用多功能性时空分异演化是自然地理环境、自然资源禀赋、社会经济因素和政策因素共同作用的结果。自然地理环境、自然资源禀赋是影响土地利用多功能性格局演变的根本因素,而社会经济与区域政策是推动土地利用多功能性格局演变的重要因素。
[Abstract]:Multi-functional land use research is an important part of land science research, which is of great significance to promote regional sustainable development. In this paper, 31 counties in the poverty zone around Beijing and Tianjin are taken as analysis units. The index system was constructed to measure the multifunction of land use in 2000 and 2014. The spatial analysis method and spatial econometric model were used to analyze the spatial and temporal differentiation characteristics of land use and its influencing factors. In 2014, the multifunctional level of land use in the poverty zone around Beijing and Tianjin showed a low level in the west, high in the east, and low in the north and south in the middle. The multifunctional level of land use increased from 2000 to 2014. The spatial pattern change is remarkable, mainly for the higher level counties extending to the Bashang plateau and the mountain areas of the dam edge, and the middle level counties shrink sharply and move eastward slightly. The spatial pattern of land production function in the poverty zone around Beijing and Tianjin changed significantly from 2000 to 2014. The main performance is the expansion of high level counties to Zhangjiakou urban area and its surrounding areas, high, middle level counties are moving northward and eastward respectively, and the trend is lower. The land life function of the low level county area from 2000 to 2014 is concentrated to the fringe area of the city area, and the spatial differentiation pattern of the ecological function has not changed greatly. Local area slightly changed. 3) the land use multifunctional space-time differentiation evolution in the poverty zone around Beijing and Tianjin is the natural geographical environment and natural resource endowment. The natural geographical environment and natural resource endowment are the basic factors that affect the evolution of the multifunctional pattern of land use. Social economy and regional policy are important factors to promote the evolution of land use multi-functional pattern.
