But the massive project practice proved these technical measure the application fundamentally has not solved the rut problem; Regarding the city"urban heat island effect"the question, the measure which uses generally is enhances the city round-off work and the expanded lawn, the water place area, but the city major part area is constructed and the path is covering, the ultra big city its round-off work extremely is in particular difficult to enhance, simultaneously the spatial distribution very is possibly imbalanced.

但是大量的工程实践证明这些技术措施的应用也未从根本上解决车辙问题；对于城市"热岛效应"问题，普遍采用的措施是提高城市森林覆盖率及扩大草地、水地的面积，但城市的绝大部分面积被建筑和道路覆盖着，尤其是超大城市其森林覆盖率极难提高，同时空间分布可能又很不均衡。

Research about China must study her control approach, because in human history, you cannot find another one like Chinese culture, which has been entirely controlling the citizen抯 life not only in political and conscious level, but also the substantial and spatial realm coving from macro-scale urban planning, through the traditional architectural construction regulation, to every sophisticated detail of daily life since thousands of years ago.

研究中国必须要研究其控制方式。因为历史上恐怕再难找到像中国文化这样，在几千年中如此事无巨细地讲究控制，不仅是在政策和意识形态上，并且也是物质化和空间化的：从城市规划的宏观规则，建造营造的中观法式，到生活用品的每一个微观细节。

The exuberant spatial effect of this small-scale Baroque circulation device is mesmerizing You half expect Georges Guetary to pop out and croon "I'll build a Stairway to Paradise," as he did so memorably in the 1951 film An American to Paris.

This article focuses on the line-line, line-region and region-region topological relations algorithm, which come down to the same question: whether there are intersections between line and line. The sweep-line algorithm was studied by many people, but has some deficiencies to be improved, in order to handle some special cases and increase program efficiency. My works as follows: rectangular envelope to reduce executive times , vector cross multiplication to determine intersection between line and line, coordinates and slope method to deal with some special cases. C program examples are showed together.(5) Finally, to prove capability and efficiency of the model and calculation method, some test systems are developed. For example, complex spatial topological relation query, parcels' exact area with the area of linear object reduced in land use, quality inspection to cadastral data according to topological rule, spatio-temporal change query of cadastral data.

将线线、线面、面面之间的拓扑关系实现的算法归结为线与线之间求交的基本问题；为处理一些特殊的拓扑关系情况，提高扫描线算法的效率，探讨了包络矩形粗滤、判断线线是否相交的矢量叉乘法、线节点重合或共线的斜率坐标判断法等改进方法；同时还设计了一种新的节点微小圆求交的算法，可应用于图斑与线状地物细分拓扑关系及地类面积的计算；（5）本文设计了实验系统，包括复杂对象的拓扑关系表达与计算程序、图斑地类面积的计算程序、基于空间拓扑关系规则的地籍数据库质量检查功能，以及时空拓扑关系和变化语义分析等原型，验证了拓扑关系表达模型和计算方法的可行性和实用性。
