【摘要】：土地,是人类生产生活的基础资源,我国又是典型的农业大国,因此,土地的集约利用发展既关乎农业的可持续性,又深深影响着我国是否能够在新时期、新背景下深化改革,从而进一步推进工业化、城乡一体化的发展。在全世界共同关注的粮食安全和人口问题的双重压力下,怎样做到土地的有效分配,如何实现土地的集约利用和可持续发展,成为学术界和实践者们共同关注的问题。沈阳市作为辽宁省经济活动的主要城市之一,在城镇化加剧进行的关键点,其土地的利用效率和可持续发展成为政府及百姓关注的重点。文章首先简要介绍了土地集约利用的概念,并从经济学角度进行科学解释;其次,介绍了土地集约利用的理论基础,包括土地供求理论、区位理论、地租地价理论和可持续发展理论;再次,通过对沈阳市土地资源概况的介绍,分析了沈阳市土地利用的现状和存在的问题,发现沈阳市土地利用结构不合理,生态结构破坏严重等问题;紧接着,以压力(Pressure)-状态(State)-响应(Response)模型为指导,利用熵值法确定权重,从沈阳市社会经济和环境等方面分3个层次共17项指标来测算土地集约度,得出的结论是在文章的统计范围内,沈阳市土地集约利用均处于中度集约水平;最后,针对前面分析的基础上提出相应的对策建议,通过促进产业结构升级、提升闲置土地的处理力度、科学编制土地规划、加强宏观调控和增强环保意识等方面来不断提高沈阳市土地利用集约度。
[Abstract]:Land is the basic resource of human production and life, and our country is a typical agricultural country. Therefore, the intensive utilization of land is not only related to the sustainability of agriculture, but also deeply affects whether our country can deepen the reform in the new period and in the new background. So as to further promote industrialization and the development of urban-rural integration. Under the dual pressure of food security and population issues of common concern throughout the world, how to achieve the effective distribution of land, how to achieve intensive use and sustainable development of land, Shenyang, as one of the major cities of economic activities in Liaoning Province, is a key point for the intensification of urbanization. The efficiency and sustainable development of land use have become the focus of attention of the government and people. Firstly, the paper briefly introduces the concept of intensive land use, and explains it scientifically from the angle of economics. This paper introduces the theoretical basis of intensive land use, including land supply and demand theory, location theory, land rent and land price theory and sustainable development theory. This paper analyzes the present situation and existing problems of land use in Shenyang, finds out that the structure of land use in Shenyang is unreasonable and the ecological structure is destroyed seriously, and then, under the guidance of pressure- state state response response model, the weight is determined by entropy method. From the aspects of social economy and environment in Shenyang, there are 17 indexes to calculate the land intensive degree. The conclusion is that the intensive land use in Shenyang is at the moderate intensive level within the statistical scope of the article. On the basis of the previous analysis, the author puts forward the corresponding countermeasures and suggestions, through promoting the upgrading of industrial structure, enhancing the handling of idle land, scientifically compiling land planning, Strengthen macro-control and environmental awareness to continuously improve the intensity of land use in Shenyang.
