摘要:
采用样地法,对湖北野人谷自然保护区的野生植物资源状况和分布特征进行了调查,采用濒危系数、遗传价值系数、利用价值系数、保护现状系数和繁殖难易系数5个组合指标和15个二级指标,计算出综合评价值,对其优先保护序列进行了定量研究,最终得出优先保护的序列为小勾儿茶>珙桐>连香树>山白树>麦吊云杉>大果青杄>水青树>杜仲>银杏>白辛树>香果树>银鹊树>猬实>紫斑牡丹>青檀>穗花杉>桢楠>秦岭冷杉>金钱槭>红豆树>篦子三尖杉>延龄草>鹅掌楸>紫茎>领春木>八角莲>华榛>厚朴>天麻>黄连>野大豆。
Abstract:Based on sample-plot survey,rare and endangered plant resources inYerengu Nature Reserve of Hubei province was investigated,and the priority conservation of rare and endangered plants was quantitatively analyzed by 5 synthetical indicators like threat coefficient,genetic coefficient,species value coefficient,comprehensive evaluation value,protection status coefficient and breeding difficulty coefficient,and 15 individual indicators.The sequence of priority protection results show that Berchemiellawilsonii>Da-vidiainvolucrata>Cercidiphyllumjaponicum>Sinowilsoniahenryi>Piceabrachytyla>Pice-a neoveitchii>Tetracentronsinensis>Eucommiaulmoiades>Ginkgo biloba>Pterostyraxps-ilophylla>Emmenopteryshenryi>Tapisciasinensis>Kolkwitziaamabilis>Paeoniasuffrutic-osa var.papaveracea>Pteroceltistatarinowii>Amentotaxusargotaenia>Phoebe zhennan>Abieschensiensis>Dipteroniasinensis>Ormosiahosiei>Cephalotaxusoliveri>Trillium tsc-honoskii>Liriodendron chinense>Stewartiasinensis>Eupteleapleiospermum>Dysosmave-rsipellis>Coryluschinensis>Magnolia officinalis>Gastrodiaelata>Coptischinensis>Glyc-inesoja.
