Grassland ecosystem in China is one of the extremely important parts of the world's grassland ecosystem. Ecological stoichiometry may help to understand different result levels of elements cycling and balance in living matter to expound China's grassland ecosystems running mechanism, which is an important part of the study of grassland ecosystem in China. To enhance the understanding of Chinese grassland ecological stoichiometry, the recent studies on the stoichiometry of grassland was reviewed here. Most studies were conducted in Inner Mongolia and Tibetan Plateau. According to the plant growth season (phenological phase),interannual succession, the variation of space and the response of global change, the internal mechanism of plant C,N and P elements, nutritional diffusion and adjustment, and driving factors were revealed. Finally the existing problems of the grassland ecological stoichiometry in China and the prospect of research contents in the future were put forward.
