| Abstract: | By applying Bayes principle,the comprehensive evaluati on of eco-climate adaptability of crop and herbage was conducted in different are as in northern ecotone.The analysis indicates that in semi-drought and drought areas,the eco-climate adaptability of herbage is obviously better than that of crop and spring wheat.Thus an all-around identification of vegetations in north ern ecotone is presented,which can be used as a reliable reference in further structure adjustment in these areas. |
