中国珍贵植物药生态分布研究

SURVEY OF ECOLOGICAL DISTRIBUTION OF THE PRECIOUS PLANT CRUDE DRUGS IN CHINA

本文概述珍贵植物药在中国三大自然区域分布的一般生态学特性，探讨了地域性分布规律及生长地对药材质量、疗效的影响。研究表明：南方山势峻峭，气候温暖多变，植物药资源种类多于北方；北方山体高大，山势平缓，气候寒冷、多干燥，植物群落单一，蕴藏量多于南方。列表详述３０种典型中国珍贵植物药的地理分布、生态环境，及其资源分布。本研究对了解中国珍贵植物药自然资源分布现状，维护其生态平衡，发展中药材生产具有重要的参考价值。

This paper generalized the ecological properties of the precious plant crude drugs distributed in three large natural climate regions and inquired into their'distribution and effects on quality and curative effect of Chinese medicinal materials. The study showes the veriety number of plant drug resources distributed in the south of China is more than that in the north, but the stock in the south is much less than that in the north, because there are many mountains and rivers in the south but the climate is warm and changeable, while the moun-tains in the north is tall and big, the climate is frigid and dry, and the phytocommunity is more simpler.This paper studied the geographic distribution,ecotope of 30 typical preciousplant crude drugs, appllied figurs and tables to present the resource distribution.This study is of important reference value to understanding the present situation of naturalresources of precious plant crude drugs in China, protecting their ecological balance, developing the production of chinese medicinal materials.
