Analysis of Animals Subsistence Based on Ecological and Climatic Conditions and Its Model of Predicting in Maqu Grasslands
Along with climate become warm, flocks and herds pup's survive rate is rising but livestock 's death rate is declining. Winter air temperature is positive impact factors for calf, warm winter calf survive rate is higher, cold winter it is lower; Midsummer lowest temperature change affect pasture's growth and cattle herd's fat; It is very distinctness which extremeness low temperature on early winter and late winter affect cattle herd's fat in naturalness feed condition;snow of the end of autumn pass by winter badly arouse cattle herd drop fat in naturalness feed condition. Sheep is fat in early autumn because sunlight is e-nough, Sheep is poor in early autumn because it is raininess and fewness sunlight;It is distinctness which extremeness low temperature on early winter affect ewe procreating and sheep herd's fat. It is filter meteorological factors which pass stepwize regression analysis,it is number grade which pass path coefficient analysis , the model of Predicting that build up even more near to the actual circumstance, which afford science gist in drove produce and rational plan drove structure.
