摘要
通过对黑沙蒿(Artemisia ordosica Krasch.)的数量性状和茎叶解剖学特征的研究,探讨其与环境因子的关系,旨在为进一步利用黑沙蒿进行区域沙漠化防治提供理论依据。试验结果表明:影响黑沙蒿数量性状及茎叶解剖学特征的主导环境因子是气候因子,而在诸气候因子中,水热综合因子和降水量又起到了主要作用。
The quantitative characters and anatomic characteristics of Artemisia ordosica Krasch. were studied, and the relationship between environmental factors and quantitative characters and anatomic char- acteristics was discussed to provide theoretical basis for the regionalization and desertification control using Artemisia ordosica Krasch. The results showed that the dominant environmental factors affecting the quantitative characters and anatomic characteristics of stem and leaf of Artemisia ordosica Krasch. were the climatic factor, in particular the hydrothermal factors and precipitation played a vital role.
