The problems of transferring farmland to grassland and food guarantee in ecotone of agriculture and animal husbandry

Aimed at the main environmental problems in the ecotone of agriculture and animal husbandry, transferring farmland to grassland is in the pride of place. Based on the problems of food guarantee after the transformation, this paper puts forward basic countermeasures for enhancing the ability of food supply in the ecotone of agriculture and animal husbandry. They are reconstructing fundamental farmland; strengthening the combination of agriculture and animal husbandry; establishing tribasic cropping structure; and applying modern dryfarming techniques so as to exploit the productive potential of arable land.\;
