摘　　要：结合文献资料对各地罂粟科植物进行调查,系统研究罂粟科植物的物种丰富度、特有性指数、相似性系数、垂直分布和水平分布。结果表明:罂粟科植物的分布中心在川、藏、陕、滇一带,特有性中心在藏、滇、川、新地区;相似性系数较大的是地理上相近、环境异质性较小的地区;垂直分布中心为3 000 m≤H(海拔)≤5 500 m,水平分布中心为80°≤E(东经)≤110°和25°≤N(北纬)≤40°;受地理环境、气候因素等的影响,罂粟科植物的分布地区在山区地带,平原地区种类贫乏。Papaveraceae plants in China were conducted to investigate their species richness, species endemic index, similarity coefficient, vertical and horizontal distribution. Their species richness center is mostly in Sichuan, Xizang, Shanxi and Yunnan Province. Otherwise, their endemic center is usually located in Xizang, Yunnan, Sichuan and Xinjiang Province. The similarity is mostly affected by the geographic localities and the different essence of environment. The vertical distribu- tion center is located between 3 000 m and 5 500 m and the horizontal center is located between 25°-40°N and 80°-110° E. Therefore, the papaveraceae is rich in mountainous areas and poor in plain areas because of geographical environment and climate.
