【摘要】：耕地资源不仅是人类赖以生存和发展的物质基础,更是保障国家粮食安全战略、维护社会稳定和保证生态环境可持续发展的基础要素。可以说,耕地资源是否得到合理、健康和可持续的利用将直接关系和影响着人类社会的生存、发展和延续。本文立足于可持续发展理论、人地关系理论、控制论等基础理论,以统筹城乡发展和新农村建设示范区的成都平原核心区为研究区域,分析其耕地资源利用现状和存在问题,从影响耕地资源可持续利用的自然因素、经济因素及社会因素等三大方面出发,构建成都平原区域耕地资源可持续利用问题的评价指标体系,分析和评价研究区2002至2010年间,耕地资源可持续利用的状态、变化趋势,并从制定政策、完善法规、提升和发展科学技术等多方面有针对性地提出了该区域耕地资源可持续利用的对策建议和措施。主要结论如下：(1)构建了成都平原耕地资源可持续利用评价指标体系立足研究区实际,对影响耕地资源可持续利用的自然因素、经济因素及社会因素等三大类的各相关因素进行综合分析,建立了包括3大类,12小项的耕地资源可持续利用评价指标体系。(2)计算并分析了成都平原耕地资源可持续利用相关评价结果。计算结果表明：2002至2010年的9年间,成都平原耕地资源可持续利用综合评价值在0.45与0.6之间变化,耕地资源利用整体处于基本可持续状态,且呈现出波动上升的变化特征。其中,2002-2003年间,由于系统自然因素子系统指标综合值和社会因素子系统指标综合值的同时下降,从而引起耕地资源系统的可持续状态整体呈现下降趋势,在状态上表现出由“基本可持续”向“不可持续”状态转变；2003-2008年间,系统经济因素子系统指标综合值和社会因素子系统指标综合值均持续提升,而自然因素子系统指标综合值持续下降,受其影响,耕地资源可持续利用综合评价值整体持续上扬,呈波动上升态势；2008-2010年间,受耕地资源系统自然因素子系统指标综合值,以及社会因素子系统指标综合值双双波动下降等的多重影响,耕地资源可持续利用综合评价值整体上呈现下行态势,系统整体毕竟“不可持续”状态边缘,形势不容乐观。(3)有针对性地提出成都平原耕地资源可持续利用的相关对策建议通过对成都平原耕地资源可持续利用的现状、变化趋势及存在的问题的综合分析,提出了加强政策、法律建设,加强土地执法和政策落实,严格土地用途管制制度及耕地占补平衡制度,严格控制非农业建设占用耕地。加强科学规划,优化用地结构,保障耕地。加强农民对耕地的保护意识,坚持用地与养地相结合,并积极运用新兴的科学技术手段的提升和发展来切实保护和提升耕地和基本农田质量,实现耕地资源的可持续利用。
[Abstract]:Cultivated land resources are not only the material basis for human survival and development, but also the basic elements for ensuring the national food security strategy, maintaining social stability and ensuring the sustainable development of the ecological environment. Healthy and sustainable use will directly affect the survival, development and continuation of human society. This paper is based on the theory of sustainable development, the theory of human-land relationship, cybernetics and other basic theories. Taking the core area of Chengdu Plain, which is a demonstration area of urban and rural development and new rural construction as a whole, as the research area, this paper analyzes the present situation and existing problems of the utilization of cultivated land resources, and analyzes the natural factors that affect the sustainable utilization of cultivated land resources. Based on the three major aspects of economic factors and social factors, this paper constructs the evaluation index system of the sustainable utilization of cultivated land resources in Chengdu Plain, and analyzes and evaluates the status and changing trend of the sustainable utilization of cultivated land resources in the study area from 2002 to 2010. And from the formulation of policies, improve the laws and regulations, The countermeasures and measures for the sustainable utilization of cultivated land resources in this region are put forward in many aspects, such as promoting and developing science and technology. The main conclusions are as follows: 1) the evaluation index body for the sustainable utilization of cultivated land resources in Chengdu Plain is constructed. Based on the reality of the research area, The natural factors, economic factors and social factors affecting the sustainable utilization of cultivated land resources are comprehensively analyzed. The evaluation index system for the sustainable utilization of cultivated land resources, which includes 3 categories and 12 sub-items, is established. The evaluation results of the sustainable utilization of cultivated land resources in Chengdu Plain are calculated and analyzed. The results show that there are 9 years from 2002 to 2010. The comprehensive evaluation values of sustainable utilization of cultivated land resources in Chengdu Plain vary between 0.45 and 0.6, and the overall utilization of cultivated land resources is basically sustainable, with the characteristics of fluctuating and increasing. During the period of 2002-2003, the comprehensive evaluation value of cultivated land resources in Chengdu Plain is in the range of 0.45 and 0.6. Because the comprehensive value of the system natural factor subsystem index and the social factor subsystem index synthesis value simultaneously drops, thus causes the cultivated land resources system sustainable state overall to present the decline tendency. From "basic sustainability" to "unsustainable" from 2003 to 2008, the system economic factor subsystem index comprehensive value and the social factor subsystem index synthesis value all continue to increase. However, the comprehensive value of the natural factor subsystem index keeps decreasing, and the comprehensive evaluation value of the sustainable utilization of cultivated land resource increases continuously under the influence of it. The index value of the natural factor subsystem of the cultivated land resource system is fluctuating and rising in the period of 2008 to 2010. As well as the multiple effects of the social factor subsystem index, such as double and double fluctuation, the comprehensive evaluation value of the sustainable utilization of cultivated land presents a downward trend as a whole. After all, the system as a whole is "unsustainable", and the whole system is at the edge of the "unsustainable" state. The situation is not optimistic. (3) put forward the relevant countermeasures and suggestions on the sustainable utilization of cultivated land resources in Chengdu Plain through the comprehensive analysis of the present situation, the changing trend and the existing problems of the sustainable utilization of cultivated land resources in Chengdu Plain. The paper puts forward strengthening policy, law construction, land law enforcement and policy implementation, strict land use control system and farmland occupation balance system, strict control of non-agricultural construction occupation of cultivated land, strengthening scientific planning, optimizing land structure. To ensure cultivated land, strengthen farmers' awareness of cultivated land protection, adhere to the combination of land use and cultivation, and actively use the promotion and development of emerging scientific and technological means to effectively protect and improve the quality of cultivated land and basic farmland, To realize the sustainable utilization of cultivated land resources.
