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.

Some models were designed where the unique tetragon and hexagon grids borrowed from the wing structure were used as the basic elements, these models were analyzed numerically, it is shown that the model consisting of tetragon grids is much stiffer than that consisting of hexagon grids, while, more material is used in the first model;crinkling models based on tetragon grids or arched models consisting of hexagon grids become more stiffer than flat ones;hybrid models consisting of tetragon grids and hexagon grids can realize a proper balance between material saving and stiffness improving.
分别提取四边形、六边形的基本网格，建立结构模型，并对它们进行非线性数值分析。研究发现：四边形网格结构刚度大，六边形网格结构刚度小；而从材料利用率角度来讲，六边形网状结构更省材料；起皱对四边形网格结构刚度有加强，而起拱对六边形网格结构刚度有提高；如果将四、六边形的网格进行合理搭配，可以使结构刚度和材料利用率得到优化。
