朝阳县野生平榛资源垂直分布规律调查

Investigation on the Vertical Distribution Regularity of the Wild Corylus heterophylla in Chaoyang County

经调查，朝阳县野生平榛资源的垂直分布规律为：中心分布区在海拔700～800m范围内；一般分布区在600～700m和800～900m范围内；散生分布区在342～600m和900～1010m范围内。海拔在〈342m和〉1010m范围内没有野生平榛资源分布，属不适生区。

The investigation showed the vertical distribution regularity of the wild Corylus heterophylla in Chaoyang county.The distribution centre area is 700-800 m.The distribution general area is 600-700 m and 800-900 m.There were few distribution between 342-600 m and 900-1 010 m. The wild Corylus heterophylla Fisch were not found in the ranges that the elevation was lower than 342 m and higher than 1 010 m.
