ABSTRACT
This paper analyzed life form, habitats and environmental stresses of medicinal plants and algal fungi collected in Chinese Pharmacopoeia(2015). ①It was found that only 0.94% of the medicinal plants mainly cultivated in field. The most common habitats of medicinal plants are divided into two types those whose natural habitats are forest margins/undergrowth(about 42.53%) and those whose natural habitats are roadside, hillside, wasteland/sand(about 43.78%). The former mainly faces environmental stresses such as weak light, pests and diseases; the latter often faces the main environmental stresses of drought, strong light, ultraviolet radiation, high temperature, low temperature(day and night or annual temperature difference is large), nutrient deficiency, pests and so on. ②Based on analyzing the strategies of medicinal plants to adapt to environmental stresses, it is pointed out that the synthesis and accumulation of secondary metabolites are the most important strategies of medicinal plants to protect against environmental stresses. In the process of long-term adaptation to specific stress, the accumulation of relevant genetic variation and epigenetic inheritance has become an important condition for the formation of quality of medicinal plants. ③It is proposed that "simulative habitat cultivation" has obvious advantages in balancing growth and secondary metabolism and guaranting the quality of traditional Chinese medicinal materials.
