To have a Correct Understanding of the Stability of Oasis in Arid Lands of China

Oasis is a characteristic eco-geographical landscape in arid lands of the terrestrial of the earth,and it is also the mayor space for production and activity of people,and the main habitats of various species of arid lands.The oasis and its stability are tightly related to the live of human being and the sustainable social and economic development in arid land.In recent years,the stability of oasis in arid lands of China is especially concerned and is therefore,becoming one of the hot issues for research.Arid lands of China are located in inland and lie between vast desert basins and huge snow covered mountains.Surrounded by desert,oasis in arid lands of China co-exists with the desert where the natural environment is adverse.Here is also the area susceptible to drought,sand storm and soil saltification.Form a short-term point of view,the natural circumstance of oasis may not be changed.Hence,oasis is especially important to people living in the region.If the oasis disappeared,the people would lose their base for life.Rapid economic development and increasing population in the oasis will certainly exert enormous influences on its surrounding circumstance and change the conditions of limited arable land and resources.Historical experiences tell us that if we do not protect the lands and resources of oasis,the balance of natural eco-geographical environment in arid lands will be destroyed,and the regional social and economic sustainable development can not be achieved.
