新疆野核桃生态气候特征的研究

Study on Eco-climatic Features of Xinjiang Wild Walnut.

一、概况新疆野核桃(Juglans regia)分布在天山山脉西部伊什格力克山北麓江嘎克萨依的峡谷之中(霍城县大西沟也有少量分布),即北纬43°19′—23′,东经82°15′—17′。现存野核桃自然分布面积约44.67ha,计3100余株。垂直分布在海拔1250—1550m之间的峡谷两侧,与天山苹果、山杏、野山楂等组成落叶阔叶野果林群落。据研究鉴定。

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.
