| 中文摘要:目的：研究不同气候特征与药用植物地理分布的关系，为药用植物的生产规划提供科学依据。方法：根据四川气象站点数据和第三次中药资源普查数据，利用地理信息系统（Geographic information System，GIS）平台，以空间可视化方式研究四川地区的气候特征和药用植物地理分布，并分析各区域药用植物地理分布特点和评价不同地区药材多样性。结果：四川地区按地形地貌分为四川盆地、攀西地区和川西高原三大区域。四川盆地冬暖夏热，气温由东南向西北递减，降水丰富，湿度较大，多阴雨天气，全年日照时间很短；攀西地区年均气温较高，冬季温暖夏季清凉，降水集中在东部地区，光热资源丰富；川西高原全年温度较低，降水较少，光照丰富。基于第三次中药资源普查数据及访谈调查得到四川药材分布图，四川盆地药用植物物种多样性最高，其次是攀西地区和川西高原。结论：四川地区药用植物资源丰富，各地域地貌和气候特征不同导致药用植物数量和种类有差异，应根据不同地域特点进行资源保护和开发。 |

| Abstract:Objective：This paper aims to study the relationship between different climatic characteristics and the geographical 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 distribution 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 region was analyzed and the diversity of herbs was evaluated in different areas.Results：According to terrain and topography，Sichuan 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 Sichuan 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 different geomorphology and climatic characteristics.So these resources should be protected and developed according to different geographical characteristics. |
