| The article analyzed the planting structure and animal husbandry structure in the "YLN" Region of Tibet by means of survey practically and analyze document.Result showed: the animal husbandry structure has little change.The planting structure has been converted from the duality of "food crop-economics crop" to the triplicity of "food crop-economics crop-forage crop".Several problems were be found in the compound agriculture-herding ecological system of this area: The grain crop is the dominant crop in cereals structure,while rape is dominant crop in economic crop,both are very single;the structure of animal husbandry is also monotonous,it's dominated by grass eating animal such as sheep and cattle.Based on the results,this article suggested: reduction the acreage of food crops,especially wheat crops;increasing economics crops acreage,particular vegetable and fruit and fodder crops acreage,adjust the proportion of "food crop-economics crop-forage crop" to 50∶20∶30;Planting grass fields,promotion of forage rotation system;increase the volume of pig and poultry farmers.Gradually establish a grain-eating and plant-consuming combination livestock herding structure. |
