Vegetation and Plant Diversity on Daotiaoshan Island

于2016年8月8日,采用遥感影像判读和实地布设样方的方法对浙江温州领海基点海岛稻挑山岛植进行维管植物与植物群落调查,并进行植物多样性分析。结果表明,稻挑山岛共有维管植物15科22属24种,其中,菊科Asteraceae,禾本科Poaceae和莎草科Cyperaceae植物属数和种数分别占该岛屿总属数和总种数的41.6%,草本植物占总种数的75%;植被覆盖率为10.57%;植被类型有灌丛、灌草丛、草丛,其中灌丛占陆域面积的5.86%,灌草丛占4.49%,草丛占0.22%;植物群落主要有厚叶石斑木Rhaphiolepis umbellata,变叶裸实Gymnosporia diversifolia,芙蓉菊Crossostephium chinense灌丛,变叶裸实、芙蓉菊和肉叶耳草Hedyotis strigulosa灌草丛,滨海珍珠菜Lysimachia mauritiana草丛。

On August 8,2016,investigations were carried out on vascular plant and plant communities on Daotiaoshan Island,Zhejiang province based on remote sensing image in 2015.The result showed that there were 24 species of 22 genera and 15 families.Species of Asteraceae,Poaceae and Cyperaceae occupied 41.6%of the total one,and herbaceous plants 75%.On the island,vegetation coverage was 10.57%,including life form of shrub,crub-grassland and grassland,accounting for 5.86%,4.49%and 0.22%of the land area.Five dominant plant communities were as follows:Rhaphiolepis umbellata community,Gymnosporia diversifolia community,Crossostephium chinense community,Lysimachia mauritiana community,G.diversifolia+C.chinense community.
