STUDY ON THE PREDICTING MODEL FOR WINTER GRASS YIELD AT THE NORTH SLOPE OF THE TIANSHAN MOUNTAINS

The effects of meteorological conditions on the winter grassyield are studied using the grass yield date at the north slope of theTianshan Mountains. Investigations are made of the key period andfactors for the grass yield formation and the cycle of the historicalseries of grass yield and meteorologiGal elements. A predicting modelfor grass yield is established based on the comprehensive considerationof the number of livestock and the meteorological conditions whichmay affect the grass yield.
