| Abstract: | Based on the characteristic of natural ecological condition and agro-pastoral production system of farming-pastoral transitional area in arid and semi-arid region, this paper put forward the integrated model of agro-grassland ecological system(sustainable utilization of land resource-plant production-animal production-social products). Some questions, such as efficient utilization of water resources, compound planting model of irrigated field, biological paling of natural grassland and rotation grazing system were studied and discussed. |
