However, the problems - the sustainable development of oasis agriculture, the ecosystem of the oasis edge, the landscape structure, the population density in oasis, water resources and land resources in oasis are deteriorating and have restricted the sustainable development of society and economy in this area. This paper summarizes the problems at present, and puts forward the concept of protecting and constructing the oasis environment and sustainable development for the sustainable development of the oasis agriculture in the Hexi Corridor.展开更多

文摘Hexi Corridor is one of the most potential areas in the China’s Western Development in 21st century.

This paper summarizes the problems at present, and puts forward the concept of protecting and constructing the oasis environment and sustainable development for the sustainable development of the oasis agriculture in the Hexi Corridor.
