As an important coal-resource based city in eastern China, coal mining activities have greatly promoted economic development to Xuzhou while resulted in kinds of blocks for sustainable development. Subsidence areas caused by coal mining activities and rapid urbanization process led to the losing of ecological function and decreasing of landscape connectivity in the city. As the important life-support system, urban green infrastructure (GI as short) has great significance in improving human well-beings. Taking Xuzhou urban area as the study object, this paper proposed a green infrastructure construction method based on the principle of ecological priority. Firstly, key ecological patches were identified by GIS and RS methods. Secondly, we established corridors by minimum cost path model. Then, we built GI network and evaluated the ecological importance of different patches. Finally, by comparing the status of patches and coal mining subsidence areas, we proposed a framework for constructing GI network in Xuzhou urban area. 展开更多

The Imperial Citadel of Thang Long is a crucial case in ancient Vietnam’s planning and design history.Although historical materials indicate that the orientation of the Imperial Citadel of Thang Long has a dialectical unity relationship with the surroundingmountains,current research is only speculative generalization and lacks empirical analysis.Based on existing findings,this paper identifies the collineation measurement as a generalmethod in the Sinosphere countries for determining spatial orientation.Using a mixed-method of historical archives,fieldwork and simulation model,this paper summarizeshistorical cluesandthreedesignperspectives related to spatial orientation by statistical analysis.Further,it analyzes the logic and application of collineation measurement in constructing the Imperial Citadel of Thang Long.The results show that Vietnamese designers used Tàn Viên Mountain as a component of Thang Long city by collineating the twomountain peaks to the west.Tàn Viên Mountain and the highlands extending eastward fromit are used as the key to establishing the position of the Imperial Citadel,setting the spatial structure of human settlements,and the development of city space.The location,layout,and formof important buildings in the Imperial Citadel are also closely related to the surrounding landscape within 50 km. 展开更多
