我国幅员广阔,地形复杂,气候多样,适宜各种植物繁衍,有“植物王国”之称。在3.5～4.5万种高等植物中,药用植物就多达0.6万种以上。如以众多的药用植物分别在我国寒带、中温带、暖温带、中亚热带、南亚热带、热带及温带、亚热带及高寒地区生长。每一个热量带都有基本相同的光、热、水等气候特征,而每一热量带又都有与这种气候特征相适应的药用植物。作为在植物分类、药材及原植物鉴定中有一定价值的表皮附属物如蜡质、毛、气孔等和植物内部构造如薄壁组织、机械组织、棚栏人组织以及细胞内含物如簇晶和多种化学成分与气候因子相联。就气候因子中的光、热水对药用植物的影响作一初步探讨。 1.光 China has a vast territory, a complex terrain, and a diverse climate. It is suitable for the proliferation of various plants and is called the “Kingdom of Plants.” Among the 3.5 to 45,000 kinds of higher plants, there are as many as 6,000 medicinal plants. For example, many medicinal plants grow in the cold, medium temperate, warm temperate, subtropical, southern subtropical, tropical and temperate, subtropical, and alpine regions of China. Each heat zone has essentially the same climate characteristics as light, heat, and water, and each heat zone has medicinal plants that are compatible with this climate. As epidermis appendages of certain value in plant taxonomy, medicinal materials, and original plant identification such as waxy, hairy, stomata, etc., and internal structure of plants such as parenchyma, mechanical tissue, shed human tissues, and cellular inclusions such as clusters And a variety of chemical components associated with climatic factors. A preliminary discussion was made on the effects of light and hot water on climatic factors on medicinal plants. 1. Light
