摘　　要：在城市内以购物出行的小汽车交通的总距离最短为目标函数,优化购物中心的空间分布.首先,按交通小区计算购物出行的轨道交通和道路交通的分担率,再以购物目的地选择为背景对土地利用和交通的关系建模,从而得到一个优化函数.其次,利用遗传算法求解该优化问题,并探讨了应用遗传算法时碰到的几个问题.最后,通过一个实例计算,验证了该方法的有效性.The study aims to optimize the distribution of shopping centers (SC) in terms of realizing the shortest car-based shopping trips in a city. First, modal split between road and railway networks is calculated, and then the interaction between land-use and transportation in the context of choosing shopping destinations is modeled to build the optimal function. Second, genetic algorithm (GA) is applied to solve the optimal problem. And several problems in application of GA are discussed. Finally, a case study, which examines of the effectiveness the method, is carried out.
