After the earthquake, the field work team surveyed and collected building damage data, calculating and obtaining more accurate intensity distributions. The focal mechanism of the main shock was calculated tentatively using digital seismic wave data from provincial digital seismic networks using the FOCMEC program and the first motions of P, SV and SH waves with their amplitude ratios. Using the location results of the main shock and aftershocks by the Anhui seismic network, combining the three-dimensional crust velocity structure imaging results of the focal region by seismic tomography, and referring on intensity distribution of the elliptic major axis' predominant direction, we conclude by comprehensive analysis that the NE-trending Susong-Zongyang fault is possibly the causative fault of the Anqing earthquake.展开更多

However, the existing conditions are not good. On the basis of existing conditions, this paper presents ideas of "development in the process of protection, promoting protection through development". The development of tourism resources in Dahengshan should properly treat the relationship between tourism reception ability and environmental carrying capacity, understand the relationship between tourism resource protection and development, restore destroyed tourism resources, make practical tourism plan, cultivate management personnel, improve service level, increase development investment, expand investment and financing channels, energetically develop tourism series products, increase propaganda, raise popularity, and strengthen regional tourism cooperation, finally build big Mingguang tourism circle. Landscape design should focus on ecology, in the hope of ranking in the tourism system of Mingguang City.展开更多

Since the natural restoration process of karst desertification mountain is very long,it needs to be supplemented by artificial vegetation restoration. This paper introduced the ecological restoration technologies implemented in karst rocky desertification mountains in Xixiu District,Anshun City of Guizhou Province,and also introduced the afforestation tending management measures. It assessed the ecological benefits of the ecological restoration project from five aspects: mountain community characteristics,vegetation coverage,species diversity,afforestation survival rate and landscape effect.展开更多
