The Spatial Relationship Research Of Yangshao Culture Sites In ZhangZhou District

The spatial relationship research of prehistoric settlement sites bases on the unearth datum of known settlement sites, settlement site as the research unit, puts the culture sites (culture relics) and the evolving configuration into the whole process of data and space to discover the layout charactors, distributing laws, grade relations and district centers.From the analysis of the shortage of traditional methods for field archaeology and cultural relic protection, the article uses the spatial analysis techniques in the spatial relationship research of Yangshao culture settlement sites to discover their spatial relations, culture spreading path, grade relations and evolving laws, obtains the following results:(1) A new technical programme for information collecting , processing and renewing in the construction of the settlement sites spatial relationship research database, and some spatial analysis motheds used in researching process are designed.(2) For the complex terrain and the distribution charactors of culture sites in Zhengzhou district, a new clustering method, PATHCLUST, is designed. From the PATHCLUST clustering results, the Yangshao culture settlement sites in Zhengzhou district could compartmentalize Yiluo river valley, Jialu river valley, Ying river valley, Shuangji river valley , etc. the culture site which is near the geographical center and has larger acreage has the characteristics of main site, and should be the district center. In the long period of human evolution, the later stage of Yangshao culture is the most prosperous stage about human activity.(3) Using the spatial analysis for the same period culture sites to make certain the existing and continuing relationships between many culture sites, the paths of culture spreading, etc. and to find the district which has the large probability for likely remain site. Research shows that there are 12 broken area about population moving and cuture spreading, these broken area should contain some likely remain sites.(4) Using the spatial distribution analysis for the same period culture remain relics to define the spatial distribution laws of relics and the paths of culture spreading roads. During Yangshao culture period, people living in Yiluo river valley and Jialu river valley are more flourishing in the usage of prodution tools and living tools and manufacture level, and more early in the building houses and planning villages. The Yangshao culture in Zhengzhou district was influenced by the culture in the west of Henan, these influence spreaded to Shangji river valley along the east of zhengzhou (now G107), in the meantime, a little influence spreaded from the upper reaches of Yin river to Yin river valley and then Shangji river valley, the spreading rate of north line is more quick than the south line,s.(5) Using the spatial analysis for the Culture layer thickness of the same period culture sites and the characteristics of spatial distribution to compare the site prosperousness, grading relationship, district center and their developing spatial relations. In Zhengzhou district, for the influence of entironment, the depositing rate of nature substances in the Yiluo river valley is more quick than it in Ying river valley, Jialu river valley and Shuangji river valley, the main deposited substances are sand granules from the northwest. Fuxitai site and Weizhangxi site, Dahecun site, Zhifang site, Guchengzhai site are most prosperous district and region center in their valley. which could put a new method to recover the unknown area in the district . Dahecun site is the center of Zhengzhou district in the period. The standardized prosperousness of known sites follows normal distribution, some unknown Yangshao later culture sites with the prosperousness between 1.0 and 1.5 should exist in the areas around Dahe site and Guchengzhai site.
