Research On Human-earth Relationship Of Gogouli Bohai State In Northeast China Supported By GIS

The research of Gaogouli,the Bohai country is an organic combination of geography and history,studies the man-land relationship between Gaogouli and the Bohai country site,has important theory and heritage value and certain cultural economic value,can further corroborate the Bohai country,Gaogouli culture in our country history and the important role of the culture development.In this paper,related documents and archaeological data of Bohai and Gaogouli sites are collectedin detail,and textual research and interpretation are carried out.Using GIS as the research method,this paper tries to establish the information system database of historical and cultural sites in Northeast China.The relationship between the spatial distribution of the site and the natural environment was analyzed qualitatively and quantitatively by analyzing the core density value,standard deviation ellipse,digital topographic analysis,buffer analysis and spatial overlay analysis of the site.The main conclusions of the study are as follows:(1)The nuclear density analysis shows that Gaogouli and Bohai have strong aggregation,and Gaogouli is mainly concentrated in Hunjiang River and Yalu River basin.The Bohai Sea mainly gathered in Longjing,Yanji,Tumen city.Bot h Gaogouli and Bohai have the highest concentration near rivers.The standard deviation ellipse analysis shows that the distribution of historical sites in Gaogouli and Bohai is not significant,but the direction of the burial sites in Gaogouli is more significant.The reason is that both Gaogouli and Bohai have experienced many times and large-scale capital relocation,so the direction is not significant,and the tombs are mostly in the birthplace of the regime,and Gaogouli people have the custom of generous burial.Ancestors and nobles are buried around their birthplaces to pray for the prosperity of the nation.(2)The study on the distribution relationship between natural environment and sites shows that the sites of Gaogouli and Bohai are mainly distributed in the elevation range of 200～500m,and the number decreases gradually with the increase of altitude.The slope of the sites is mostly flat or gentle,but the burial sites are mostly distributed in the places with higher slope.Most of the sites are located on the southern slope,southwest slope,southeast slope,west slope and flat land with good sunshine conditions,while the other slope aspect sites are few.The largest number of sites were located within 0.5—3km from the river.The northeast region had a monsoon climate,and the closer it was to the river,the greater the risk of flood.Therefore,the distance of0.5—3km was the best choice for hominins.Vegetation coverage tends to decrease from the southeast coast to the northwest,and there is also local differentiation caused by the comprehensive action of rivers,terrain and other geographical factors.Most of the sites are in areas with less vegetation coverage today.The site is currently under land use,possibly due to the lack of development in these areas to protect the site.
