| 摘 要： | 为保护野生濒危药源植物-盾叶薯蓣(Dioscorea zingiberensis C.H.Wrig h),笔者就其资源储量和地理分布进行了调查研究,将盾叶薯蓣在我国的地理分布划分为两个区,绘出该资源的地理分布示意图,我们对第I分布区资源储量进行了精度估算,结果为:从总体上第I分布区平均蓄积量可估计为44.053 g/m2,此种估计产生的误差限为7.147克,相对误差限0.162,作这种估计的精度为0.838,可靠性为0.95。此结果为保护生物学工作提供了有价值的资料。

| Abstract: | The author invested and studied on Dioscorea zingiberensis C.H.Wrigh about its resources amount stories and geological distribution in China in order to protect this species for it is dangerous. Distribution region which includes two parts is defined by author. Not only the distribution area figure is given but also resources stories in the first distribution area is exactly estimated. The conclusions are: on the whole, an average amount is 44.053g/m 2, There could be 7.147g error in such an evaluation, relative error is 0.162, this estimate precision is 0.838, reliable is 0.95. |
