摘要
目的:摸清西双版纳野生重楼资源的种类、分布区域及资源现状等,为开展重楼人工种植,进行合理保护和开发研究提供依据。方法:通过走访调查、实地调查和样本采集鉴定相结合的方法,对全州26个乡镇的野生重楼资源进行了调查。结果:所调查的26个乡镇全部有野生重楼分布,但居群内个体多在20株以下。主要分布于海拔1 000~1 500 m的南亚热带季风常绿阔叶林下和竹林下,喜生长于箐沟、山谷等小环境中。分布的种类有滇重楼、七叶一枝花、南重楼3种,其中以滇重楼数量最多。结论:西双版纳地区海拔800 m以上、水源丰富的地域均适宜重楼生长,但野生重楼资源正在急剧减少,迫切需要开展重楼人工种植,并对野生资源进行合理保护和利用。
Objective: To explore the species,distributing and resource of Paris genus plants in Xishuangbanna area of Yunnan province.Method: Two steps,talking with the folk doctors and field survey,were employed to explore the resource status of Paris plants.Twenty six villages and towns,which are at an elevation of 500 m to 2 000 m,were investigated.Result: A total of 214 specimens were collected and identified according to morphological characteristics.All investigated spots had Paris genus resources distribution but there always had a small Paris population less than 20.The Paris genus is an understory plants which lives always in a specific environment beside creek in hill valley and with many commensal plants such as bamboo and broadleaf.Three species of Paris,P.polyphylla var.yunnanensis,P.polyphylla var.chinensis,and P.vietnamensis were collected and identified.Conclusion: Paris genus resources declined rapidly in recent year,particular the P.polyphylla var.yunnanensis.Developing the breeding and cultivation technologies and enhancing the resources protection are needed urgently.
