【摘要】：城镇化是经济快速发展的必经之路,也是现代社会的重要特征。中国在三十多年的城镇化建设历程中经济取得了快速发展、人民生活得到了巨大改善,但这背后一系列问题也逐渐显现,如土地不合理利用而导致的城镇规模无序蔓延、土地利用结构不合理以及土地生态系统破坏、城市生存环境恶化、水土流失等土地生态问题,无一不对人类社会的可持续发展造成巨大威胁。此外,随着近几年城镇化进程的快速推进,土地刚性需求激增,土地利用强度增加、方式改变,对土地生态系统造成了更深刻的影响。为此,政府提出了新型城镇化的建设思路,强调“人”的核心地位。新型城镇化要求生态优先、文明发展,其中土地作为城镇化发展的重要载体和劳动对象具有稀缺性、不可移动性和利用的不可逆性,无疑成为各项工作的重中之重,因此我们应从区域生态规划、生态产业、生态城市等各个方面入手促进土地的生态利用,打造绿色、低碳、集约、智能的城镇人居环境,从而实现社会的可持续发展。目前全国“新型城镇化”建设和“美丽乡村”计划等如火如荼,临沂市在城镇化进程快速推进和打造生态园林城市的背景下,土地利用的生态性成为城镇建设不可忽视的一部分,然而脆弱的土地生态环境、外延式城市规模扩张、城区绿地分布不均匀等土地生态问题和利益驱动的土地利用方式、技术支撑不足以及土地生态利用理论不成熟等都威胁着土地的生态利用。文章结合文献分析、实证分析和比较分析等方法对临沂市2005-2011年城镇化过程中土地利用变更数据进行了比较分析,总结出临沂市土地利用中出现的问题,所做的努力,并在分析借鉴国内外土地生态利用的经验的基础上从宏观到微观进行了土地生态利用的方案设计,宏观上提出生态功能区、生态镇规划建设和环城绿带建设,以及城镇立体化发展模式,微观上提出全方位的土地生态利用的努力,如改变观念、建筑节能等。
[Abstract]:Urbanization is the only way for rapid economic development and an important feature of modern society. In the course of more than 30 years of urbanization construction, China has achieved rapid economic development and greatly improved people's living standards. However, a series of problems have gradually emerged behind this, such as the sprawl of urban scale caused by irrational land use. The unreasonable structure of land use, the destruction of land ecosystem, the deterioration of urban living environment, soil erosion and other land ecological problems, all of which pose a great threat to the sustainable development of human society. In addition, with the rapid development of urbanization in recent years, the demand for land rigidity has increased sharply, the intensity of land use has increased, and the mode has changed, which has a deeper impact on the land ecosystem. Therefore, the government puts forward the new-type urbanization construction thought, emphasizes "the person" the core position. New urbanization requires ecological priority and civilization development, in which land, as an important carrier and labor object of urbanization development, has the characteristics of scarcity, immobility and irreversibility of utilization, which undoubtedly becomes the most important part of all kinds of work. Therefore, we should start from the regional ecological planning, ecological industry, ecological city and other aspects to promote the ecological use of land, create green, low-carbon, intensive, intelligent urban human settlements, so as to achieve sustainable development of society. At present, the construction of "new urbanization" and "beautiful countryside" plan are in full swing in the whole country. Under the background of the rapid development of urbanization and the construction of ecological garden city, Linyi City is in full swing. The ecological nature of land use becomes a part of urban construction that can not be ignored. However, the fragile land ecological environment, the extension of urban scale, the uneven distribution of urban green space, and so on, are the land ecological problems and the land use mode driven by interests. Insufficient technical support and immature theory of land ecological use threaten the ecological use of land. Combined with literature analysis, empirical analysis and comparative analysis, this paper compares and analyzes the data of land use change in the urbanization process of Linyi City from 2005 to 2011, summarizes the problems in land use in Linyi City and the efforts made. On the basis of analyzing and drawing lessons from the experience of land ecological utilization at home and abroad, the paper designs the scheme of land ecological utilization from macro to micro level, and puts forward the ecological function area, ecological town planning and construction and green belt construction around the city macroscopically. As well as the three-dimensional development model of cities and towns, microscopically put forward the all-around efforts of land ecological utilization, such as changing ideas, building energy saving and so on.
