Digital Construction of Rural Landscape Based on DEM:A Case Study of Xiangyu Village of West Beijing

[Objective]The paper uses Geographic Information System(ArcGIS)as a platform to discuss the study of DEM data on the digital construction of rural landscape databases and the coupling relationship in geographic space of rural landscape.The aim is to further expand the coverage of China's land space digitization and provide practical theoretical basis and development possibility of quantitative planning for village level administrative zoning research.[Method]In this paper,Xiangyu Village,Junzhuang Town,Mentougou,West Beijing,is selected as the research object,and the document space database of the study area is constructed by building digital elevation model(DEM),ArcGIS stacked map weighting and visual interpretation methods.Moreover,its elevation equivalence,slope direction,and water flow direction are visually analyzed.[Result]The mountainous terrain and hydrological characteristics of Xiangyu Village are roughly consistent with the village layout;the living environment of Xiangyu Village is consistent with the terrain and texture,and it belongs to the rural landscape system of mountains,valleys and small watersheds.[Conclusion]The results obtained through data visualization analysis are basically consistent with the traditional village planning pattern of Xiangyu Village;the rural landscape based on village level administrative divisions is still in the traditional planning stage,and there is great development space for village level geographic spatial survey.Therefore,it is necessary for relevant practitioners to make more contributions to fill the full coverage of China's land space digitization.

Textual Research on The Great Conqueror's Building Garden

The Great Conqueror’s Building Garden (Bawanglou Garden) evolved from the Great Conqueror’s Hall of Xiang Yu’s royal architecture in the Chu and Han Dynasties,and it was the stately main building where General Xiang Yu was busy with the country governing,symbolizing the imperial palace of the Western Chu State.Its demolition in the Northern Song Dynasty came into being as a result of Huanglou Tower built by Su shi.In the Qing Dynasty,the new Great Conqueror’s Building became an official garden building dedicated to Xiang Yu,and his concubine Yu as well as the government office.The relevant literatures and historical data have shown that the architectural form,scale,layout and morphological characteristics of the Great Conqueror’s Building in the Qing dynasty were quite different from those of the original one,not only in the form evolution from hall to building,but also in the evolution of use function from administrative place to sacrificial place.
