In this paper, the habitat of Cerasus clarofolia was investigated and analysed, under natural conditions the growth of Cerasus clarofolia is influenced by low temperature of winter. The seeds of Cerasus clarofolia need low-temperature to germination. The seedling with 4 leaves grew well after introduction, the survival rate reached 79.7%. Planting with clear water was found easier to take roots, the roots were come from the lenticels, under diffent environmental conditions, the lenticels formed morphological, physiological differences are the important factors take roots for Cerasus.

Lancang county, Yunnan Province is located in the southwestern border of Yunnan Province, , China and has abundant forest resources. At the same time, there are many cases of illegal logging and deforestation in Lancang county. In the county, the cases of illegal logging and deforestation of Pinus kesiya were mainly carried out by rural personnel, the single-person case was converted into a form of gang, the remoteness of the crime site makes it difficult to find and investigate, especially in most of the rural collective forests, etc. The main reasons for its occurrence are: the general public’s lack of legal awareness and economic poverty. A series of preventive measures and strike strategies, such as perfecting the system of recruiting personnel and intensifying the crackdown on such cases, were proposed to provide theoretical support for the protection and development of Pinus kesiya resources Lancang County.

Plant material evidence inspection is Mahonia bealei (Fort.) Carr., Mahonia fortunei (Lindl.) and Mahonia bodinieri Gagnep. are three common medicinal plants commonly found in Mahonia. In this study, gas chromatography-mass spectrometry (GC-MS) was used to compare the chemical constituents of stems and leaves of these three plants. The results showed that 6 of the volatile oils of the three plant species contained the same chemical composition, which was neophytadiene, palmitic acid, n-dodecane, octacosane, erucamide, and vitamin E oil, but the percentage content was difference. The main components of the volatile oils of the three plant stems were different. Erucamide was only detected in Mahonia fortunei (Lindl.) Fedde, oleic acid amide only detected in Mahonia bealei (Fort.) Carr. , and oxidized cyclooctene , and four compounds such as triphenylphosphine oxide was detected in Mahonia bodinieri Gagnep. ..
