The paper aims to introduce the author's investigation of the Shiyang River's environment problems and the proposals of the author on measures to be taken to solve the problem with the river. Shiyang River is one of the inland rivers in Hexi Corridor in Gansu province, which plays a very important role in economic and social development of the area. Irrational use and development of the river has brought many environment problems with the River, such as, the snow-covering line moving up, the groundwater decline, water quality deterioration, soil desertification, vegetation degeneration, the land and soil desertification and salinization, etc. On the basis of a vast investigation, it has been found that the key link to protection of the water resources and the sustainable development of the local agriculture is to develop the soil-conserving forests and promote the water-resource protection in the southern Qilian mountains and fight against the desertification in the basin area. For the whole basin, it is necessary to enhance the protection measures through the law and policy implementation. In doing so, it is essential to strengthen people's awareness of the importance of the ecosystem protection. To approach the problem in an up-to-date and scientific way, systematic experimental projects are to be done to study how to use the modern science and technology to save the vast basin area in a modern sense with its chief purpose of promoting the vegetation and reduce the soil erosion. In addition, it is reasonable to reduce the number of reservoir and the water quantity kept in the flood season. It is more important to develop the industrial production and service industry in the central oasis to promote the local economy by setting up small towns and adjusting the agriculture structure. In the north desert area, to recover the degeneration of sand-fixing forests, return farmlands to the grassland or to the natural status, strictly forbid reclaiming the wasteland and overexploiting the desert resources.
