The Loess Plateau is mainly situated in the middle part of the Huanghe River and in the North along side with the Great Wall, starting from the Riyue Mountains in Qinghai Province in the west to the Taihang Mountains in the east, and stretching to the Qingling Mountains in the south, covering 7 provinces or autonomous regions such as Qinghai, Gansu, Ningxia, Shanxi,. Nei Mongol, Shaanxi and Henan. Its total area is 530,000 km2, of which the typical loess area is 275,600 km2 with a total population of about 60 million. Grievous water losses and soil erosion are the sources of not only the infertile land and the poverty of the people over the loess plateau but also the harmfulness caused by the Huanghe River. At the same time, the permanent control of the Huanghe River must proceed to control water losses and soil erosion. And yet, the control of the loess plateau must be the comprehensive, all-round and regional control. As a matter of the fact, the control of the loess plateau is a problem of land realignment with the rational land use as its core. The rational land use over the loess plateau must proceed to protect and adjust land resources closely related to its control so as to ensure the rational land use and on going exploitation of land lesources. Based on the rapid and all-round recovery of vegetation and the prevention of water losses and soil erosion, the reproductive ability of land resources should be continuously raised, the ecological environment can be further improved and the production potential of natural resources of agriculture may be brought into full play. Thus, steadily increasing agricultural production, raising economical returns and improving the living standard of the people can be surely achieved. For this reason, good conditions must be created for building the loess plateau into a prosperous and socialist paradise so as to develop the vast northwest China rapidly and to bring the Huanghe River Under permenant control. The urgency of controlling the loess plateau is shown in grievous destruction of land resources and continuous worsening of ecological environment. There are the "5 indiscriminations"(that is, indiscriminate cultivation, indiscriminate grazing, indiscriminate fuel collecting, indiscriminate felling and indiscriminate medicinal herbs gathering) so that droughts, winds, frosts and freezesoccur very often.
