Based on the domestic current researches, the relations between climatic change and Chinese Loess Plateau evolution during the Quaternary arc summarized，and the main characteristics can be listed as follows:① the crucial factors of Loess Plateau formation arc the serial otherness structural variation of Chinese mainland caused by the Himalayan Syntaxes from the "hernary;② during the Pleistocene the strong wind caused by "hibetan Plateau apophysis brings great deal of power一dust from the inland desert in middle Asia zone to Loess Plateau zone, which was formed accordingly;③present monsoon occurred after "hibetan Plateau had reached certain height during the Pleistocene, then the higher of 'hibetan Plateau is, the stronger of the barrier against summer monsoon is. "hhe warm and wet climate in Loess Plateau turned into cold and drought，and the types and distrbution of vegetation adjusted accordingly;①the adaptability of vegetation could repeat according to climatic changes, namely the
distributing zone moves from north to south on the basis of climatic changes in temperature and precipitation;③during the Pleistocene natural corrosions played great role in soil and water losses in Loess Plateau，and during the Holocene the soil and water losses accelerated because of human activities;⑥soil and water losses in Loess Plateau arc influenced by the geological condition，precipitation,vegetation and human activity, and its spatial variety is obvious.
