Throughout the course of history, all thesocial improvement and economic development are deeply concerned with soil loss and ecologicalenvironmental protection. It is now a common sense that soil and water conservation is the safetyinsurance for national ecology and its development. For the past long period of time, soil and waterloss has been recognized as 'the No.1 killer' to the ecological environment. The nation is on thestags of the critical conditions for its development. China has massive mountain and upland areawith complicated geological conditions and accelerated human destruction and serious soil and waterloss. Based on rich historical documents, renovating experience and detailed analysis of the datacollected in field experiments and field surveys for soil and water conservation, this paper aims toreview the general characteristics of soil and water loss, to explore the relationship between soiland water conservation and sustainable economic development, and to provide relevant strategies forsoil and water conservation in China.展开更多

Based on the recent investigation on sandy desertification, this paper analyses the status such as the type, area, distribution and damage of sandy land desertification in the plateau. Through the analysis on the factors affecting sandy desertification in the region’s natural and socio-economic systems as well as the processes and their interrelations, it can be concluded that sandy desertification in the Qinghai-Tibet Plateau resulted from the combined actions of normal natural sand drift processes, natural sandy desertification processes caused by climatic changes and man-made sandy desertification caused by improper human activities. In addition, it also predicts the possible developmental trend including the increase in desertification area and the enhancement in desertification developmental degree with the exacerbation of the complex processes, and finally puts forward some strategic suggestions to combat sandy desertification in the coming years.展开更多
