| Abstract: |
| Through discusssing phenological characteristic of winter wheat , the influence of meteorological factors during wheat growth period to the output has been analysed by means of statistical methods, the model to forecast the climatic yield of wheat has been given and the degree of risk of planting winter wheat has been estimated, the winter wheat ecoclimate compatibility has been discussed and the index system to delimit ecology climatic region of wheat has been established. The wheat ecoclimatic regions have been delimited according to the index system and the methods to promote the degree of utilizing ecoclimtic resource have also been given. |
