【摘要】 土地是“万物之母”,是人类赖以生存和发展的基础。在所有的自然资源中,土地资源对于社会经济发展具有不可替代的重要作用。然而,伴随着社会经济的发展,城市化进程的加快,以及人口的增加,人地矛盾异常紧张,这些矛盾也日益影响着经济的发展。在社会经济发展中,如何减少对环境的破坏,改善生态环境,实现社会、经济、环境的协调发展,已成为人们关心的话题。土地的协调利用不仅能合理地安排区域土地资源利用,优化土地的配置,而且能促进土地资源高效集约利用。土地利用协调性评价研究对于探求一个经济、社会与资源环境相协调,充分合理利用土地资源的可持续发展道路具有重要的理论和现实意义。本文正是基于这样一个理论和现实背景,在梳理了土地协调利用相关研究的基础上,以土地利用协调性评价为突破口,运用熵权理论和协调度模型,从资源环境、经济、社会三方面筛选评价因子,构建了土地利用的协调性评价指标体系,并对大丰市土地利用协调性进行评价。研究结果表明：①8年来,大丰市土地利用三大系统变化趋势差异明显,土地利用经济子系统得分和土地利用社会子系统得分一直处于上升趋势,其中土地利用经济子系统得分上升速率较快,而土地利用生态环境子系统得分变化较为明显,有升有降,2005年,土地面积特别是耕地面积的进一步锐减,在2006年陡降至最低点后又有缓慢上升的状态；②参照协调度等级评价标准,发现8年来协调度差异也较为明显,土地协调基本处于由不太协调向基本协调过渡的状态,离高度协调尚有较大一段差距,有着充分挖掘的潜力；③从定性和定量两个方面来分析土地协调利用影响因素。定性方面：自然环境因素、社会因素、经济因素和政策因素对土地协调利用产生影响；定量方面,运用多元线性回归模型得出地均GDP、人口密度、城市人均绿地面积对土地协调利用的影响较大,其中,人口对其变化最为显著。在以上分析的基础上,提出了土地协调利用的对策建议：科学规划各功能区布局；正确引导经济发展,处理好土地资源与经济发展的关系；树立科学用地、协调用地的观念；严格控制人口增长,优化人口结构；强化大丰沿海滩涂的优化与管理,构建环境友好型土地利用模式等。更多还原

【Abstract】 Land, as the "mother of all things on earth", is the foundation of human existence and development. In all natural resources, land resources will play an important and irreplaceable role in the economic and social development. However, with the development of economy and society, the acceleration of the urbanization process,and the increasing population growth, the contradiction between human and land is exceptionally tense. So in the development of economy, how to coordinate the development between society, economy and environment,reduce the destruction of environment is a mental theme of human beings.The coordination evaluation of the urban land use is good to arrange the regional land use reasonably and conduct an optimize way for the allocation of land resources. According to the coordination degree of the land use social system, land use economic system and land use eco-environment system, we can judge the coordinated development of land use,analyze the social and economic development level of land use and the eco-environment situation of land use. In this way, we can provide a scientific guidance to decide a rational land use way.This article is based on a theoretical and practical background, doing a research on an evaluation of land coordination use in Dafeng City Jiangsu Province.Based on the entropy and taken the evaluation of land use coordination as a breakthrough, this paper filters evaluation factors through resources,environment, economics, society, structures the urban land use coordination index system and evaluates the land use coordination in Dafeng.The evaluation results shows:①During recent 8 years, The beneficial scores of the land use social system, land use economic system and land use eco-environment system are different from each other;scores of land use social system, land use economic system shows upstairs,the growing rate of land use economic system shows obviously;but the score of land use eco-environment system varies frequently,asending or dropping from year to year,in 2005,as the declining of plow,it drops to the lowest and then asends slowly.②Refer to the appraisal table of land-use system coordination degree,the differences of coordination degrees are obviously,mainly locates the ststement from not too coordinated to coordinated elementally,has a gap comparatively large from coordinated in a high degree,and it has a potential to excavat.③we find the main factors of land coordination use qualitatively and quantitatively. Qualitatively we find the factors are environment, society, economy and policy. Using the multiple stepwise regression, we find that the main factors of land coordination use are population growth, economic development and the level of afforesting quantitatively. Among these factors, population growth is obviousBased on the evaluation results of Dafeng city,we put forward the countermeasures and suggestions to lead land use in a coordinated way,there are as follows:Handling the relationship between the land use and economic development correctly and driving the economic growth reasonably, Establishing the notion of using the land scientificed and coordinated,Controlling the population growth strictly and optimizing the population structure, Creating the environmental and friendly land use model,Completing the land use system, Strengthening the protection of the cultivated land and increasing the productivity of land etc.更多还原
