摘要
为探讨大熊山樱属(Cerasus)植物资源的种类、分布、群落结构和观赏性特点,同时为其开发利用提供依据,2017-2019年,对大熊山的樱属植物资源进行了普查、重点调查、样地调查和物候观测。结果表明:在该区域海拔435-1520 m的山坡、沟谷和悬崖地段分布了迎春樱桃(C.discoidea),华中樱桃(C.conradinae)、山樱花(C.serrulata)、尾叶樱桃(C.dielsiana)、雪落樱(C.xueluoensis)5种野生樱花;开花顺序为从低海拔到高海拔,花期从2月下旬持续至5月上旬,长达60d。大熊山野生樱花资源较为丰富,樱花资源总量约6万株,总面积约300 hm2;樱花资源在花期、花色、花量、树形等方面各有特点,具有较高的观赏和利用价值。
