Sport under the background of modern history of china blended into the course of historical development as a carrier for nation and race strengthening, country survival and national modernization, concessively went through such two stages as physical strength value view and national sports value view, and consequentially established a national psychological foundation for the generation and selection of the competitive sports "nationwide system" and "olympic glory seeking plan" after new china was founded; after new china was founded, china chose olympics once again for its needs for communicating with other countries and fulfilling its century dream, and for the great renaissance of the chinese nation.

中国近现代史背景下的体育，作为强国强种、救亡图存和民族现代化的载体而融入到历史进程中，先后经历了体力价值观、民族体育价值观两个阶段，并由此为竞技体育"举国体制"和"奥运争光计划"的产生与选择奠定了民族心理基础；新中国成立后，为了加强国际交往和圆世纪梦想的需要，为了中华民族的伟大复兴，中国再次选择了奥林匹克。

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.
