Study on Eco-climatic Features of Xinjiang Wild Walnut.

The Xinjiang wild walnut and cultivated walnut belong to tbe same species,which demands strict ecological conditions.Based on more than 3 years observation and research, this paper analyzed the eco-elimatic factors for the su(?)vival and thriving of Xinjiang wild walnut in the front mountain areas of midtemperate Yili Valley. Fuzzy analysis of similarity and priority ratioes of climatic factors are made,and regions most suitable for the growth of walnut are identified.The analytical results are in ac(?)ordance with production reality.It (?)rovides a scientific basis for the rational exploitation and utilization of climatic resources in the front mountain areas in Yili Valley and for the development of economic forests and rapid-growlng timber forests.
