Objective: Analyze the ecological adaptable regions for the resource reservation and the expanding cultiva-tion of Quisqualis indica L. Methods: The Traditional Chinese Medicine Geographic Information System (TCMGIS) was used to analyze the ecological adaptable region. Results: The 17 provinces (city, municipalities) were the ecolog-ical adaptable region for Q. indica L. The 100% ecology similarity regions are mainly in 16 provinces (city, munici-palities), including Guangxi, Guangdong, Hunan, Fujian etc., which area accounts for 1 012 895.98 km2. Among these, the area in Guangxi province is the largest (195 313.64 km2), the second is Guangdong (150 276.36 km2), the following order is Hunan(128 925.29 km2), Fujian (101 471.16 km2) and Y unnan (100 660.83 km2). The 95%~100%ecology similarity regions is located in 16 provinces (city, municipalities), including Y unnan, Sichuan, Guizhou, Hubei province etc., which area accounts for 362 366.25 km2. The largest area is in Y unnan province (92 399.04 km2), followed by Sichuan(76 122.32 km2), Guizhou (43 902.38 km2), Hubei (31 760.32 km2) and Jiangxi (29 770.09 km2). Conclusion: The results are consistent with the survey results and the previous reports. To promote the develop-ment of Q. indica L. cultivation, the planting scientifically and quality evalution should be further conducted on the basis of the results by system analysis.

OBJECTIVE:To provide reference for the patent application of artificial cultivation and seed treatment technology of Paridis Rhizoma and natural resources protection. METHODS:Retrieved from State Intellectual Property Office patent database,“Paridis Rhizoma”and“Paris polyphylla”were used as search keywords from 1985 to March 31,2015;Paridis Rhizoma cultiva-tion and seed treatment technology patents as research object were analyzed in fields of the amount of patent application,regional construction and legal status,etc. RESULTS:Among 54 Paridis Rhizoma cultivation patent application,there were 19 applications from Yunnan,9 from Sichuan,8 from Hubei,5 from Anhui,4 from Hunan,3 from Guizhou,2 from Jiangxi,1 from Fujian, Shanxi,Jiangsu,Guangxi respectively;there were 18 licensed patents,and 13 licensed patents maintained more than 3 years, among which 1 patent right transferred;from aspect of patent without right,6 patent right were given up due to fail to pay annual fee,1 rejected and 5 withdrawn;from main types of patent proposer,enterprise submitted 24 patent application,universities 15, scientific research institutes 8 and other 7. 24 enterprise patents involved 21 enterprises,indicating that patent protection net didn’t form due to disperse proposers. CONCLUSIONS:Patent application is mainly from Yunnan. There still are some problems,such as small number of patent applications,poor quality of application writing,little patent transformation. It is suggested to plan artificial cultivation technology,enhance the quality of patent application,pay attention to patent operation and achievement transformation and other measures,in order to protect Paridis Rhizoma resource and industrial development.
