内容 研究概要:The status of desertification and revegetation of the Mu-Us sands was analysed using remote-sensing data and geographical information system. As a whole, the process of revegetation dominated from 1978 through 1993. The changes from active sand dune to fixed sand dune were most clearly observed in the suburbs of the Yulin city, where tree-planting and revegetataion-works have been concentrated by the government. The increase of vegetation-index was prominent in the area of irrigated crop land. The decrease of vegetation-index was particularly recognized in the broad meadow in the upper valley of the Bai-He reservoir. It is possibly due to the complex effect of the overuse of grassland and drought condition.
