气候特征与药用植物地理分布的数值分析——以四川省为例
Numerical Analysis of Climatic Characteristics and Geographical Distribution of Medicinal Plants——Taking Sichuan Province as an Example
摘要
Abstract
Objective:This paper aims to study the relationship between different climatic characteristics and the ge-ographical distribution of medicinal plants,providing scientific basis for production planning of medicinal plant.Methods:In this study,geographic information system(GIS)technology was used to analyze climate characteristics and geographical distri-bution of medicinal plants in Sichuan region in a spatial visualization way based on the data of Sichuan's meteorological station and the third census of traditional Chinese medicine.The geographical distribution characteristics of medicinal plants in each re-gion was analyzed and the diversity of herbs was evaluated in different areas.Results:According to terrain and topography,Si-chuan region was divided into three parts,the Sichuan basin,Panxi area and western Sichuan plateau.Sichuan plateau,a place where is warm in winter and heat in summer,is humid because of its rainfall,meanwhile,its temperature decreases from the southeast to the northeast and annual sunshine time is short.Panxi area,a place with high mean annual temperature and abundant solar energy,has cool summer and warm winter and its eastern region is rich in precipitation. Compared with Si-chuan basin and Panxi area,western Sichuan plateau is a region with sufficient sunshine,but its annual temperature is lower and its annual precipitation is less. Then we obtained the geographical distribution of medicinal materials in Sichuan region based on the data of the third census of traditional Chinese medicine and interview investigate.The diversity of medicinal plant species in Sichuan Basin is the highest,followed by Panxi area and Western Sichuan plateau.Conclusion:The results showed that Sichuan region was rich in medicinal plant resources.The number and type of medicinal plants were various due to the dif-ferent geomorphology and climatic characteristics.So these resources should be protected and developed according to different geographical characteristics.关键词
