Abstract:

The pasture-crop system, including arable lands and grasslands, is food resource and habitats for human beings and animals. This system is confronting serious threats from climate change, population increase and water and energy shortages. In order to improve land productivity and to feed the increasing population, some developed and developing countries have converted grasslands to arable lands during the last few decades. Grasslands were substituted by arable lands and be changed into simplified systems, which were associated with a substantial decline in biodiversity and habitats loss, degradation and fragmentation. Many researchers and scientists have suggested strategies and policies implementing in international pasture-crop systems. Those strategies and policies include pasture and crop rotation, crop planting cooperative development with pasture planting and livestock feeding, Scientific grazing and feeding management, and the same preferential policy for both crop planting and pasture planting. Those strategies and policies not only increase lands productivity, but also protect the ecological environment, which are beneficial to human sustainable development.

Key words: International pasture-crop system, Threat, Resolution

摘要:

草田是人类和动物等的食物资源和栖息环境,具有涵养水源、保护生态多样性、减缓气候变化和维持地区可持续发展等作用。目前气候变化、人口增加、水资源和能源资源短缺等对国际草田资源带来严重威胁。为了提高土地生产力,养活不断增加的人口,近几十年大部分国家将半自然状态草地转变农耕地,农耕地管理引起动生物多样性降低和植物群落栖息环境碎片化、退化和消失等。如果国际草田实施粮草轮作、粮草畜协同发展、科学放牧和饲养管理、粮草同等种植优惠政策等,不仅可以提高土地生产力,而且有利于保护生态环境和人类生存可持续发展。
