【摘要】：随着科技的进步和社会的发展,人类对土地利用的深度和广度都有所提升,人类活动与自然环境之间的矛盾也逐渐加剧,人地关系受到越来越多的关注。协调人地关系,从土地利用的实践角度探索人类发展与环境生态之间的平衡,走稳步可持续发展之路,成为现代人类无法回避的必然选择。本研究从土地利用角度入手,构建了基于土地利用的人地关系理论框架,运用人类活动压力指标模型、人地关系协调度模型、人地关系响应度模型、空间分析等研究方法构建了基于土地利用的人地关系评价体系,全面探讨南宁市人类活动对资源环境的压力强度作用,以及资源环境对人类活动的承载作用,并评估了南宁市2005-2012年时间和空间上人地关系协调状态,旨在为南宁市的人口与土地、人口与经济、土地利用与社会发展之间的平衡发展提供参考。整体而言,论文从土地利用变化视角系统研究了南宁人地关系演变规律,主要结论为：(1)南宁市2005-2012年人地关系协调水平由良好协调向高度协调发展,耦合度由磨合阶段向高水平耦合发展,2010年后协调度上升趋势平缓：(2)2005-2012年南宁人类活动压力指数持续上升,资源环境抗压能力呈倒“N”型发展,土地利用强度指数增长速率大于资源环境承载指数速率；(3)南宁市土地利用对人地关系的响应度和响应度指数呈90度“八”字型趋势,即目前南宁市人类活动强度导致资源环境水平下降且程度增大,呈负响应,对南宁市人地关系协调起胁迫作用；(4)南宁市12个行政区单元的人地关系协调度以人口规模扩张强度大、土地利用强度高的青秀区、良庆区为中心进行辐射,距离中心越远,协调度越低。基于以上主要研究结论,文章提出了南宁市人地关系目前存在的问题,提出了可从人口的数量和质量上优化“人”、从产业结构和新型生态农业上优化“地”、通过以市区带动县域的以点带面形式促进土地利用强度弱的县域城市发展、缓解人类活动强度大的市区人地关系压力,达到区域内部平衡稳步、协调可持续发展的目标。
[Abstract]:With the progress of science and technology and the development of society, the depth and breadth of human land use have been improved, the contradiction between human activities and natural environment has been gradually intensified, and the relationship between man and land has been paid more and more attention. To coordinate the land relationship, to explore the balance between human development and environmental ecology from the perspective of land use practice, and to take the road of steady sustainable development has become an inevitable choice that modern human beings cannot avoid. From the perspective of land use, this study constructs a theoretical framework of human-land relations based on land use, using the human activity stress index model, human-land relationship coordination degree model, human-land relationship response degree model. Spatial analysis and other research methods have constructed the evaluation system of human-land relationship based on land use, and comprehensively discussed the pressure and intensity effect of human activities on resources and environment in Nanning City, and the bearing role of resources and environment on human activities. In order to provide a reference for the balanced development of population and land, population and economy, land use and social development in Nanning from 2005 to 2012, the paper evaluates the coordination of man-land relationship between time and space in Nanning City, and aims at providing reference for the balanced development of population and land, population and economy, land use and social development in Nanning. As a whole, from the perspective of land use change, this paper systematically studies the evolution law of human-land relationship in Nanning. The main conclusion is that the coordination level of human-land relations in Nanning from 2005 to 2012 has changed from good coordination to highly coordinated development. The coupling degree developed from running-in stage to high level coupling. After 2010, the degree of coordination increased gradually, and the pressure index of human activities in Nanning from 2005 to 2012 continued to rise, and the capacity of resources and environment to resist pressure showed an inverted "N" type development. The growth rate of land use intensity index is greater than that of resources and environment bearing index. That is, at present, the intensity of human activities in Nanning City leads to a decrease in the level of resources and environment and an increase in its degree, showing a negative response. The degree of coordination of human-land relations in the 12 administrative districts of Nanning City is based on the intensity of population expansion and the intensity of land use in Qingxiu District with high land use intensity, and the Liangqing District is the center of radiation, the farther away from the center, The lower the degree of coordination. Based on the above main research conclusions, the paper puts forward the problems existing in the relationship between people and land in Nanning, and puts forward that "people" can be optimized in terms of population quantity and quality, and "land" should be optimized in terms of industrial structure and new ecological agriculture. By promoting the development of the county cities with weak land use intensity in the form of driving the county by the urban area, the pressure of the relationship between the people and the land in the urban areas with the high intensity of human activities can be alleviated, and the regional internal balance can be achieved steadily and the goal of coordinated and sustainable development can be achieved.
