The results are listed as follows:(1) In peneplain with plenty water-resource, hexagonal spatial structure of urban system can be formed. Due to differential competed function of central places, the hexagonal system is distorted. The result is that the area covered is decr eased and the girth is unchanged——but every border is usually unequal;(2) A pattern of pentagonal system evolves from hexagonal system controlled by a river;(3) A pattern of quadrilateral develops from hexagonal system under two parallel rivers;(4) The equal distance distribution of central places in narrow geographic space has its special reasons. The results are very important for understanding urban's formation and development and urban plan in Huang-Huai-Hai plain.

本文通过自然地理因素中水文、地形这两个重要要素对城镇体系空间结构形成的影响，分析了华北平原区在不同要素影响下的城镇体系空间结构样式：①在水源充足的准"均质"河北冲积平原上，基本满足六边形形成条件，但由于周边中心地发展竞争力不同，故使得正六边形发生畸变——覆盖面积减小而周长却保持不变；②构建了在一条河流影响下的六边形网络结构朝五边形网络演变的模型；③构建了在平行状河流作用下六边形网络向四边形网络演替的模式；④指出了在水源充足的狭长地理空间，城镇体系空间结构发育成等间距的现象与原因。

According to this understanding, this thesis tries to modify PSO algorithm in order to improve its quality of solutions. The main approches include: using uniform design to ensure the uniform distribution of initial particles in the design space; adding mutation operation to increase the diversity of particles; decreasing the maximum velocity limitation and the velocity inertia automatically to balance the local and the global search efforts; developing a new approach to treat the design variables exceeding the bounds; using extensive local searches to escape local minimum. The overall effect of these approaches can yield better results for most test problems.
