| 摘 要： | 为探讨土壤含水率对中国沙棘人工林种群数量的影响,在不同水分条件下对中国沙棘人工林持续4年进行观测。结果表明,克隆种群数量、母株种群数量以及子株种群数量随着土壤含水率的增加均呈二次抛物线变化规律;随着年份增加克隆种群数量、子株种群数量最大值时最佳含水率不断升高;在同一土壤含水率情况下,母株存活数量和存活率则逐年下降。

Response of Population Quantity of Hippophae rhamnoides Plantation on Soil Moisture |

| Abstract: | In order to study the effects of soil moisture on population quantity of Hippophaerhamnoides,Hippo-phae rhamnoides ssp.plantations were observed under the condition of different soil moisture for four years.Result showed that with the increasing of soil moisture,clone population quantity,population quantity of mother plant and population quantity of daughter ramet changed as a convex parabola;while population quantity of the clone and popu-lation quantity of daughter ramet are bigger with the increase of the year,the optimal soil moisture rises continuous-ly.But under the condition of the same soil moisture,number of survival rate and survival rate of mother plant de-crease year by year. |
