长柄双花木为我国特产种 ,产于浙、赣、湘三省 ,属国家二级珍稀濒危保护植物。首次报道了该种在浙江的分布数量 ,共计 3 6 72 0丛 ,数量居三省之首。纠正了前人报道的一些谬误 :①文献认为该种在开化已灭绝 ,经查证分析 ,系前人将分布点龙洞误为龙潭之故 ,本次调查在开化重新找到了该种 ,且发现了大面积分布。②文献记载龙泉分布点海拔为 10 0 0m ,经调查实际为 6 5 0～ 80 0m。③文献记载该种为阴性树种 ,经实地观察 ,认为应属中性树种。调查发现该种在浙江的分布特点与其他两省有所不同 ,一是海拔较低 ,二是生境以沟谷为主。详尽记述了该种在浙江的地理分布、生境特点以及群落学特征 ,分析了群落的演替趋势 ,并就其保护与利用等方面提出了具体建议。参 1 1
Long-handled double flowers for our specialty products, produced in Zhejiang, Jiangxi and Hunan provinces, is a national two rare and endangered plants. For the first time, the distribution of this species in Zhejiang was reported, amounting to 36,200 clumps, ranking the first among the three provinces. Correct some of the fallacies reported by predecessors: ① literature that the species has been extinct in Kaihua, the verification analysis, the Department of the former will be distributed Longdong mistakenly mistaken for Longtan, this survey in Kaihua rediscovered the species, and found Large area distribution. ② records Longquan distribution point elevation of 10 0m, after investigation of the actual 650 ~ 80 0m. ③ documented that negative species, the field observation, that should be neutral trees. The survey found that the distribution of the species in Zhejiang Province and the other two provinces are different, first, lower elevation, and second, habitat to valley-based. Detailed description of the species in Zhejiang geographical distribution, habitat characteristics and community characteristics, analysis of the community succession trend, and its protection and utilization of specific recommendations put forward.
