【摘要】 随着我国经济的高速发展和城市化的进程的加快,城市的扩展迅速,全国各地掀起了一轮又一轮的新城区建设热潮。新城区的开发建设均成为城市发展和社会、产业、经济结构调整的重要途径和热点。尤其是对于中小城市,新城区开发建设已经成为地方政府最重要的国民经济增长极。土地作为新城区建设的载体和基本条件,社会经济发展中一个最为活跃的生产要素,土地开发强度指标(容积率、建筑密度、建筑高度)的合理与否直接关系到城市建设与发展的方向、空间和后劲。土地开发强度调控已逐渐成为城市提高土地有效利用和提高环境质量的重要手段,同时也是调控人口密度、合理布局城市基础设施、塑造良好的环境品质及生活空间、实现城市科学发展的关键所在。但在计划经济体制向市场经济体制转变的背景下,由于市场经济自身“功利性”、“片面性”的弊端,迫使土地的开发强度往往趋向最大化,从而容易导致城市空间的整体性较差,城市景观混乱,城市特色消失,社会矛盾激化。新城区城市规划在强度控制方面存在的突出的问题,集中反映在开发强度指标的确定存在理性依据不足,随意性大,在使用中缺乏针对性、操作性不强的问题,造成新城区开发难以同时兼顾环境、经济、社会的协调持续发展需要。在以大规模土地出让为特征的城市土地开发与再开发的趋势下,开发强度指标的合理确定和有效控制尤为重要。土地开发强度因涉及多方利益主体,包括政府、开发商及城市居民,自然成为利益主体关注的体育焦点。因此,土地开发强度指标体系的制定也成为城乡规划编制和管理的重要内容。目前国内关于城市土地开发强度的相关研究较多,研究方法和理论基本是定位于大城市,对于经济社会发展水平相对落后的中小城市,却并不完全适用。增城市作为以县级市为建制的中等城市,新城区的建设与大城市在自然条件、经济水平、发展阶段、城市功能定位、土地征用等存在明显的差异,因此开发强度的制定和管理存在显然的不同。本研究是在自己近10年来的规划编制和管理的实践基础上,以增城市新城区为研究对象,着重探讨土地开发强度指标在使新城区规划编制、管理过程中的使用与实践,对如何完善土地开发强度指标制定和实施管理提出建议,以便为同类型的中小城市新城区规划建设提供借鉴和参考。更多还原

【Abstract】 With the rapid development of economy and acceleration of the process of urbanization,many cities are expanding rapidly,and a upsurge in the new urban construction is in the making all over the country. The construction of new urban has become the important channel and the hot spot that can cause the city development and social economic restructuring. Especially for small and medium-sized cities, it has already become the most important growth pole of the local national economy. The land as the carrier and basic condition of the new urban construction is the most active one of production factors in the process of socioeconomic development, so it concerned the space, potential and direction of the urban construction and development directly that the index of land development intensity (plot ratio, building density, building height) is reasonable or not. Regulation of land development intensity has gradually become an important means by which the land utilization and environment quality can be improved effectively, and meanwhile it is also crucial in many aspects such as proper redistribution of urban infrastructure, regulation of population density, shaping of good living space and environmental quality, and achieving sustainable urban development. However, under the background of transforming from planned economy to market economy, land development intensity is always forced to tend to the maximization because of the defects of market economy itself ,such as“utilitarian”and“onesideness”,thus this will lead to some consequences easily, e.g. disorder in whole urban space, mess in townscape, fading of urban features, and intensification of social contradiction. These serious problems existing in new urban planning ,considering land development intensity control , are centered on these aspects as follows: establishment of land development intensity index is too rational and lacks in sufficient theoretical foundation, and the index lacks for direction and operability during use, consequently the triadic relation among economy, society and environment is very difficult in satisfying the demands of developing coordinately and sustainable in the process of new urban construction. Under the tendency of urban land development and redevelopment characterized by a large-scale land remising, it’s particularly important to determine reasonably and control effectively the index. Land development intensity involving multi-stakeholders, including governments, developers and city dwellers, have naturally become the main focus of interest. Therefore, land development intensity index system has become an important part of the organization and management for urban and rural planning. Nowadays there are many relevant researches on the intensity of urban land development in our country, but the research methods and theories are mainly based on big cities, so they aren’t applicable to small and medium-sized cities whose levels of socioeconomic development are backward comparatively. As a county-level and medium-sized city,new urban construction of Benching has significant differences in respect of natural conditions, economic level, development stage and city function orientation, compared with big cities, so there should be different in formulation and management of land development intensity accordingly. Based on the near 10 years’practice of the author on the planning and management, the paper regards the new urban of benching as the research object, and puts emphasis on the uses and practices of land development intensity in the process of making and implementing the planning, then this paper provides some suggestions on how to improve the formulation and management of land development intensity, in order to offer reference and consult for planning and construction of new urban of the similar small and medium-sized cities.更多还原
