Sehool of Pastoral Agriculture Science and Technology , Lanzhou lIniversity , Lanzhou 730020 , China) Abstract: Through analyzing the existing food safety model and food consumption trends in China , we found that the demand for rapid growth in feed will take up 70% of the food equivalent , which is causing great pressure on food safety. Thus the traditional single arable agriculture will be unable to meet peoples requirements for food. As a creative thinking about food safety , grassland agriculture contains enormous production potential and developing plant-eating livestock can solve the problem of feed lack. After years research , grassland workers in China have proposed various grassland agricultural innovatio
