Abstract: Agricultural production efficiency,crop livestock integration, grain problem, layout of agricultural production and object of the study of sustainable agriculture have been highlighted by scientists and decision makers in China.These problelms play a crucial role not only in correct policy making, but aslo in the direction of agricultural research. There have been, however, some confusions and misunderstandings in the current viewpoints held by some of the scientists and decision makers in China. Pointing at this situation, this paper makes a significant discussion for the sake of finding a correct answer through a profound analysis and statement based on the researches conducted by the authors themselves and a large amount of study results collected at home and abroad.The conclusions are: (a)Sustainable agriculture is an academic term, not a new model for replacing the conventional agriculture, and the study of sustainable agriculture should give priority to developing input reducing technology and increasing farmers income in order to make Chinas agriculture environmentally sound and healthy; (b)The emphasis of researches on crop livestock integration should be shifted to focusing on how to adjust the composition of energy and protein in feed supplied by cropping and consumed by livestock; (c)The main ways for eliminating the increase of grain shortage in China are to put the strategy of grain substitution into practice as soon as possible and to properly restrain food consumption which has been highly speeded up; (d)According to the principle of less external input and higher efficiency, the priority of developing grain production should be placed on the high yield farmland rather than on medium yield farmland; and (e)The energy efficiency in Chians agricultural production has increased from time to time, which is very important for a correct policy making in China's sustainable agriculture.

Key words: ustainable agriculture, croplivestock integration, grain, layout of agricultural production, agricultural production efficiency
