为满足轨道交通站点周边土地开发的需要，形成TOD开发格局，从两个层面建立分区体系，提出了一套不同区域的开发强度指标值作为容积率的土地开发控制指标，并根据开发强度指标值的不同，将车站划分为综合站和一般站两类，并对不同区域的开发强度指标值进行了分析，确定了不同区域的开发强度指标值，并对不同区域的开发强度指标值进行了比较，确定了不同区域的开发强度指标值。利用非参数统计中的线性回归拟合地价和距离两个参数，确定轨道交通对周边地区的影响半径，并将车站周边地区划分为三个圈：300米内为高密度复合开发区，300 m ~ 600 m为中密度区，600 m ~ 1000 m为低密度区。密度。开发强度随距离车站的增加而降低，商业开发应在核心圈内。运用经济学理论分析了土地开发强度与收益之间的关系，结果表明，存在使收益最大的最佳容积率，建立了以政府收益最大化为目标的土地开发强度优化模型，最后利用房价指标和开发强度指标计算出各区域的最佳开发强度值沿着深圳的轨道交通3号线。
In order to meet the needs of land development around the rail transit station and form the development pattern of TOD,the zoning system is established from two levels,one is station category and the other is development circle.A set of development intensity index values for different areas are formulated as the land development control guidelines of floor area ratio.The stations are divided into comprehensive station and general station in view of their functions.The impact radius of rail transit on surrounding area is determined by using the linear regression of non-parametric statistics to fit the two parameters of land price and distance to the station.Then the area surrounding station is divided into three circles:the area within 300m is high-density composite development zone,the area between 300m～600m is medium-density and the area between 600m～1000m is low-density.The development intensity decreases with the increase of the distance to the station and the commercial development should be within the core circle.The relationship between land development intensity and profit is analyzed by economic theory.The results show that there is the best floor area ratio to make the largest profit.It establishes the optimization model of land development intensity with the target of maximizing the government's profit,and makes the sensitivity analysis.At last the best value of development intensity of each area is calculated using the indicators of housing price and development cost along the Rail Transit Line 3 in Shenzhen.
