【摘要】：土地安全问题既是国家安全体系中重要的组成部分,更是实现国家安全的根本保证[1]。近年来,由于全球人口总数的大幅度增加,城镇化水平的不断提高,工业化进程的加速,使得人类对土地的开发利用强度加大,随之而来的土地安全问题逐渐凸显。边境地区作为保卫国家安全的前沿阵地,保障边境地区土地安全对维护国家安全具有重大意义。在当前党中央高度强调加强国家安全工作的背景下,边境地区土地安全已经引起政府和学术界的广泛关注。本文选择广西边境地区作为研究区域,重点参考谭荣所著《中国土地安全评论》,从经济、社会、生态3个层次出发,结合研究区土地安全特点,全面考虑对土地安全有潜在影响的人类活动及重要因素,选取17个评价指标构建土地安全评价指标体系,运用改进后的熵权法计算各项指标权重,基于物元理论构建广西边境地区土地安全评价模型,对广西边境地区2000~2014年土地安全状况进行评价,深入分析其土地安全动态变化规律。并进一步以县级行政区作为评价单元,对广西边境地区8个县(市、区)2000年、2005年、2010年、2014年土地安全进行评价,剖析广西边境地区土地安全空间差异规律,为实现土地可持续利用、开展区域生态环境保护、推进边境土地安全、完善国家安全体系提供借鉴和科学依据。本研究的主要结论如下:(1)广西边境地区土地安全水平呈上升趋势。2000~2014年,广西边境地区土地安全状态由“不安全”转为“临界安全”,安全等级隶属度值均在(-1,0)之间,表明安全状况并不完全符合“不安全”或“临界安全”的要求。和2000年相比较,2014年广西边境地区土地安全整体水平相对于、、级别的隶属度逐渐减弱,而相对于、的隶属度在增强。由此可见,广西边境地区在国家西部大开发和边境扶持政策的支持下,通过退耕还林、土地整治,着重加大环境保护力度,使得该区域土地安全系统的改善已初见成效。(2)广西边境地区土地安全水平呈区域差异。广西边境8个县(市、区)土地安全水平总体呈上升趋势。2000年、2005年,8个县(市、区)土地安全状况均处于“不安全”状态;2010年,那坡县、龙州县、凭祥县、宁明县土地安全状况有所改善,土地安全等级均提升至“较不安全”状态;2014年,除防城港市市辖区的土地安全状况为“临界安全”之外,其余7个县(市、区)土地安全等级均达到了“较安全”水平。(3)广西边境地区土地安全水平受多因素共同制约。影响广西边境地区土地安全水平的主要制约因素包括人均耕地面积、单位耕地面积粮食产量、单位耕地面积化肥施用量、土地后备资源率、经济密度、边境贸易建设用地弹性、城镇化率等。建议通过制定《广西边境地区国土规划》,全面划定永久基本农田,实行集约用地考核制度,推进边境贸易和边境生态旅游发展,走绿色发展道路等措施来提升广西边境地区土地安全水平。
[Abstract]:Land security is not only an important part of national security system, but also a fundamental guarantee to realize national security. In recent years, due to the large increase of global population, the continuous improvement of urbanization level, and the acceleration of industrialization process, the intensity of land exploitation and utilization has been increased, and the land security problems have been gradually highlighted. As the frontier position to protect national security, it is of great significance to safeguard the land security in border areas. Under the background that the CPC Central Committee highly emphasizes the strengthening of national security, the land security in the border area has attracted extensive attention of the government and academic circles. This paper chooses the border area of Guangxi as the research area, and mainly refers to Tan Rong's Land Security Review of China, starting from the three levels of economy, society and ecology, combining the characteristics of land security in the study area. Considering the human activities and important factors that have potential influence on land security, 17 evaluation indexes are selected to construct land security evaluation index system, and the weight of each index is calculated by using the improved entropy weight method. Based on matter-element theory, the evaluation model of land security in Guangxi border area is constructed, and the land security situation in Guangxi border area from 2000 to 2014 is evaluated, and the law of dynamic change of land security is deeply analyzed. Taking the county level administrative region as the evaluation unit, the paper evaluates the land security of 8 counties (cities and districts) in Guangxi border area in 2000, 2005, 2010 and 2014, and analyzes the law of spatial difference of land security in Guangxi border area. In order to realize the sustainable use of land, develop the regional ecological environment protection, promote the border land security, improve the national security system to provide reference and scientific basis. The main conclusions of this study are as follows: (1) the level of land security in the border areas of Guangxi is on the rise. From 2000 to 2014, the state of land security in the border areas of Guangxi changed from "unsafe" to "critical safety". The membership values of the safety grade are between (-1 ~ 0), indicating that the safety condition does not fully meet the requirements of "unsafe" or "critical safety". Compared with the year 2000, the overall level of land security in the border area of Guangxi in 2014 was gradually weakened in terms of the level of membership, while the degree of membership relative to the degree of membership was strengthened. It can be seen from this that the Guangxi border areas, supported by the state's large-scale development of the western region and the border support policy, put emphasis on increasing environmental protection through returning farmland to forests and land renovation. The improvement of the land security system in this region has already achieved initial results. (2) the level of land security in the border areas of Guangxi shows regional differences. The land security level of 8 counties (cities and districts) in Guangxi is on the whole rising. In 2000 and 2005, the land security status of 8 counties (cities and districts) is in the state of "insecurity". In 2010, Napo County, Longzhou County, Pingxiang County, Ningming County land security situation has improved, the land security level has been upgraded to "less safe" state; In 2014, in addition to the "critical safety" of the Fangchenggang municipal district, the remaining 7 counties (cities), (3) the land security level in the border area of Guangxi is restricted by many factors. The main factors influencing the land security level in the border areas of Guangxi include the per capita cultivated land area, the grain yield per unit cultivated land area, the amount of fertilizer applied per unit cultivated land area, the rate of land reserve resources, the economic density, the elasticity of land for construction purposes of border trade. Urbanization rate, etc. It is suggested that, through the formulation of the "Land Planning for the Border region of Guangxi", the permanent basic farmland should be comprehensively delineated, the system of assessment of intensive land use should be implemented, and the development of border trade and border ecotourism should be promoted. Take green development road and other measures to improve the level of land security in Guangxi border area.
