The study framework of land use/cover change based on sustainable development in China

LIU Yan sui, CHEN Bai ming (Institute of Geographic Sciences and Natural Resources Research, CAS, Beijing 100101, China)  
Being the core and frontier issue in the global environmental change and sustainable development disciplines, studies on land use/cover change (LUCC) has gained increasingly attention. China, restricted by its large population and less land, is one of the developing countries facing serious ecological and environmental problems in the world. Many problems of sustainable development confronting China have inherent and inevitable associations with LUCC. Therefore, systematic LUCC researches, aiming at the implementation of sustainable development strategies in China, have great significance in both academic and practical respects. Their relations between the problems of sustainable development and LUCC, and the research objects, contents, investigative methods and key issues of LUCC based on sustainable development in China are briefly discussed in this paper. The interrelationship between LUCC and sustainable development in China is very complex. Generally speaking,the linkage can be shown as the balance between land water resources demand and supply. Thus, the orientation and content of LUCC and sustainable development researches should be developed along with the critical issues for sustainable development driving force of human being scenarios of LUCC optimized decision making for sustainable development. Meanwhile, different situations under different temporal and spatial dimensions should be incorporated into the researches. The key issues to be studied are how to reveal the land supply and demand relationships under the multiple driving forces, as well as its changing extents and influences. Upon them, the framework of scientific decision making and comprehensive management for LUCC in China, which is confined by the sustainable development relationship between food and resources supply, ecological protection and economic growth, is proposed.
