The overall situation of the world's current disciplinary development in the sciences dealing with resources and the environment features the following characteristics: the guiding thoughts of holism and systematics are leading a growing trend of all-round enhancement while inter-disciplinary integration and crossbreeding between the natural sciences and social sciences or the humanities are emerging in the research of resources and environment problems; the holistic, regional and systematic approaches have become the research mainstream, more attention is paid to the long-term and continuous accumulation of data and a country's strategic demands in the resources and environment fields are more clearly defined and stepped up. Eased on an analysis of the holistic situation, strategic focuses for the research work of the CAS in resources and environment fields are selected when the academy faces the national demands and global ST frontiers. These focuses include prospecting theories and technologies for energy and mineral resources in urgent need, regional environment evolution and global change, oceanographic research, rebuilding the deteriorated ecosystems and expertise in the protection and revival of fragile ecosystems, the impact of environmental pollution on ecological security, human health and pollution control.
