结合实际工作经验，从样地和样方的设置、蕴藏量调查的野外工作、蕴藏量和允收量的计算等几个方面对药用植物蕴藏量调查方法进行了探讨。单位面积药用植物株数与单位重量药材相当的药用植物株数的比，为单位面积蕴藏量。将单位面积蕴藏量与地表面积相乘，即为按坡度梯度、坡向分类的蕴藏量；它们的和，即为该品种的总蕴藏量。为了在一个采收周期内采收利用现有的药用植物资源，年允收量为药材蕴藏量与采收周期的比。

Combined with practical experience, a stock investigation method of medicinal plants is approached from different angles, such as setting up the sample field and quadrant, doing the fieldwork, calculating the stock and annual possible gathering volume, etc. Depending on the geographical distribution features of the plants, the sample field are pointed out on topographic maps (1: 50 00 or 1: 10 000). Quadrants are set up at random or regularly according to the species and density of the plants. The locat ion, area, slop orientation, gradient,elevation, and vegetation of the sample field, also the area of quadrant and the amount of plants investigated, should be carefully noted down during the fieldwork .The quadrants are classified according to their slop orientation and gradient, then convert the recorded amonut of plants in quadrants to the amount of plants per square kilornetre. The stock of Per square kilometre is equal to the volume of the amount of the plants in per square kilometre divided by the amount of the plants per kilogram. The stock of per square kilometre multiplied by the area of earth's surface is the stock volume, which should be classified by the slop orientaion and gradient. The sum of the volunes is the total stock of a kind of plant.As to gather and make use of the medicinal plants in a gathering circle period, the annul possible gathering volume should be calculated as the stock volume of the plant divided by the gathering circle period.
