Starting with environment protection, energy-saving and integrated resource utilization, supported by technology advancement and environmental investment, sustainable development strategy can be implemented to drive the circular economy. Thereby, the responsibility to realize the long-term harmony and synergy between society and enterprises is taken by Baosteel.展开更多

The mission of geomorphological environment research is to explore the most basic environment and features of our Earth＇s surface morphology. The results can be applied to resource evaluation, environmental protection and reducing and preventing geological disasters. Thus, it can serve to help achieve sustainable development. This paper examines the Shenzhen east coastal zone as a case strongly influenced by urban expansion. We use modern geomorphological theory and methods, along with GIS and RS techniques, to reveal key characteristics of the geomorphological environment and landform classification. Furthermore, coastal ecosystem evaluation and regional resources sustainable utilization should be considered relative to the corresponding geomorphological environment. Based on this study, we conclude that modern geomorphological theory and methods, supported by ＂3S＂ techniques including GIS, RS and GPS, can play an important role in resolving the environment, resources and population problems as well as sustainable development challenges facing humankind at present.展开更多

This study indicates that not only have wetland areas been reduced by half, but also their ecological environments have been degraded because of rapid economic development and population increase. Suggestions based on this research are made to reconstruct the ecological environment of the wetlands and return them to their previous state.展开更多
