It has explained the spatial-temporal view of "the unity between heaven and human" and human's subjective ideological connotation in Leichang Former Residence. From the perspectives of the spiritual connotation of roof decorations, grading system of roofing tiles and manifestation form, it has deeply revealed the important expressive force and representativeness of roofs in architectural group, pointed out its aesthetic feature and spiritual restriction to architectures even human's behavior, and showed that the roof is the architectural factor directly manifesting "rituality" and "the unity between human and heaven" in Chinese traditional culture.展开更多

Under this background, people also gradually turn their attention to the renovation and planning of rural human settlements. Based on practical investigation, this study analyzed the importance of village renovation planning and summarized the basic principles of village renovation planning. Based on the theory of The Sciences of Human Settlements, applying rigorous comprehensive research methods, it put forward the main contents of village renovation planning: land use planning, economic and industrial planning, comprehensive renovation of residential environment, renovation of residential buildings, environmental improvement, infrastructure renovation and construction management measures. This study took Xukou Village renovation planning of Peixian County, Xuzhou City as an example, systematically and comprehensively analyzed the existing problems, and put forward targeted renovation strategies to build a village renovation planning system and to provide good experience and reference for the sustainable development of rural human settlements and provide reference and basis for the government to formulate relevant policies and take corresponding measures and solve practical problems.展开更多

The results indicated that the main causes of poaching and other illegal activities are associated with poverty, ignorance and culture and commercial purposes. The results further illustrated that poaching cases decreased in the Volcanoes National Park where, from 2018, the snares removed from the park reduced from above 1000 to 600 snares. In the same year, only 3 poachers from Kinigi and Shingiro Sectors were arrested. The findings illustrated that introducing of revenue sharing scheme where, 10% of the park’s revenues are shared to the local communities living adjacent to the park, and constructing a buffalo wall stone around the Volcanoes National Park are of the important measures which contributed to solve completely the problems of poaching and human-wildlife conflicts in the volcanic area. However, some respondents reported that the construction of buffalo wall did not prevent animal from escaping the park, they have proposed the construction of strong fence such as electrically fenced wall.展开更多
