【摘要】：草田是人類和動物等的食物資源和棲息環(huán)境,具有涵養(yǎng)水源、保護生態(tài)多樣性、減緩氣候變化和維持地區(qū)可持續(xù)發(fā)展等作用。目前氣候變化、人口增加、水資源和能源資源短缺等對國際草田資源帶來嚴重威脅。為了提高土地生產(chǎn)力,養(yǎng)活不斷增加的人口,近幾十年大部分國家將半自然狀態(tài)草地轉(zhuǎn)變農(nóng)耕地,農(nóng)耕地管理引起動生物多樣性降低和植物群落棲息環(huán)境碎片化、退化和消失等。如果國際草田實施糧草輪作、糧草畜協(xié)同發(fā)展、科學放牧和飼養(yǎng)管理、糧草同等種植優(yōu)惠政策等,不僅可以提高土地生產(chǎn)力,而且有利于保護生態(tài)環(huán)境和人類生存可持續(xù)發(fā)展。
[Abstract]:Grass fields are food resources and habitats for human beings and animals, which have the functions of conserving water, protecting ecological diversity, mitigating climate change and maintaining regional sustainable development. Climate change, population growth and shortage of water and energy resources pose a serious threat to international grassland resources. In order to increase land productivity and feed a growing population, in recent decades most countries have transformed semi-natural grassland into agricultural land, which has resulted in the reduction of animal biodiversity and fragmentation of the habitat of plant communities. Degeneration and disappearance, etc. If the international grass field implements the rotation of grain and grass, the coordinated development of grain, grass and animal, the scientific grazing and management, and the preferential policy of equal planting of grain and grass, it can not only improve the land productivity, but also help to protect the ecological environment and the survival and sustainable development of human beings.
