珍稀濒危药材白木香产地适宜性分析

目的：通过分析白木香的适宜生长区域，为白木香种植产区以及合理规划生产布局提供科学依据。方法：以白木香实际调查采样点为依据，选取1月平均温、7月平均温、土壤、降水量等影响白木香生长发育的关键生态因子，采用《中药材产地适宜性分析地理信息系统》（TCMGIS—Ⅱ）对白木香在中国的生态适宜区进行分析。结果：白木香较适宜区分布于我国广东、广西、海南、福建、云南等省区的部分地区。结论：TCMGIS-Ⅱ系统分析的结果与调查结果、历史记载及文献报道相符合。在系统分析结果的基础上，应科学地、有选择性地进行适宜种植区规划，进一步检测沉香品质，选择最适宜地区。

Suitability Evaluation of Rare and Endangered Aquilaria sinensis＇ s Producing Area

Objective ：Through analysis the China,it will provide scientific basis for reasonable appropriate the place of production region for aquilaria sinensis in planning and layout of aquilaria sinensis. Methods：According to actual sampling point, the key ecological factors such as average temperature of January and July, soil, rainfall, precipitation, and so on have been selected. The TCMGIS-Ⅱ （Suitability evaluation geographic information system of traditional Chinese medicine producing area）was developed and used to analyze the appropriate producing area of aquilaria sinensis in China. Results： Parts of Guangdong, Guangxi, Hainan, Fujian, Yunnan are the adapative areas according to the eco-soil condition that the medicinal plants needed. Conclusion：Results of the TCMGIS-Ⅱ system are consistent with the survey results and previous reports. On the basis of the results by system analysis, we should plan the suitable planting areas scientifically and selectively, further test the Aquilaria sinensis quality. Then, we can choose the most suitable areas.
