| 摘 要： | 通过分析我国食物消费趋势发现，需求增长较快的饲料用粮将占去70%的食物当量，我国现有的农业结构模式面临巨大挑战。作为构建粮食安全的思路创新，草地农业蕴含着巨大的生产潜力。我国草业工作者经过多年试验研究，提出了南方农区水稻/玉米-黑麦草轮作、南方山区和牧区多年生混播草地栽培、黄土高原粮草轮作、西北绿洲农区“公司+养殖区+农户”肉牛养畜以及农牧交错带多年生牧草栽培-“粮+草+牲畜养殖”系统等草地农业创新模式，对于食物的增产增收、节粮替粮作用明显。因此，可以通过草地农业建立持续高效的农业生态系统来保障粮食安全。

| 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 innovation models on food security, such as rice/corn-Italian ryegrass rotation system of rural areas in south China, perennial mixed sown pasture system of hill country and pastoral areas in China, grass-crop rotation system of loess plateau area in China, the “company+breeding area/farmer specialized cooperatives+farm households” cornstalk-beef cattle breeding system in Hexi Corridor and perennial mixed sown pasture-“grain+grass+livestock breeding” system in the ecotone between agriculture and pasture in north China. The results showed that conspicuous effects could be achieved to save food, and increase production. Therefore, we can build efficient grassland agriculture system to protect food safety. |
