Evaluation on Regional Suitability of Four Famous Chrysanthemum Morifolium

This study aimed to investigate the comprehensive ecological factors of four famous kinds of Chrysanthemum morifolium(i.e.Chuju,Huaiju,Boju and Hangju) and their regional suitability in China.Based on field survey,specimen examination and literature investigation,ecological factors and appropriate production area were analyzed by Traditional Chinese Medicine Geographic Information System(TCMGIS-II).The results showed that the suitable region for Chuju and Huaiju is the largest and that for Hangju is the smallest.The proper region(with similarity of 95%-100%) of Chuju accounts for 139046.4 km2,including eight provinces/municipalities and 215 counties/cities.The largest area among them is Anhui province with area of 50026.9 km2,followed by Jiangsu(36805.5 km2),Hubei(30986.8 km2),Henan(12609.1 km2) and Hunan(4398.8 km2) province.The appropriate region of Huaiju,which shares the similarity of 95%-100%,accounts for 218502.2 km2 and includes 9 provinces/municipalities,such as Henan,Shandong,Shanxi province,etc.The largest area for Huaiju is Henan(80110.5 km2) province,followed by Shandong(73897.3 km2),Shaanxi(21293.5km2),Jiangsu(14709.9km2) and Shanxi(11224.2km2) province.The suitable region(with similarity of 95%-100%) of Boju covers 4 provinces and 72 cities/counties with the area of 42765.5km2,including Anhui(23286.9 km2),Henan(10212.4 km2) and Jiangsu(area 9196.3 km2) province.The distribution of Hangju is the most scattered,including 10 provinces/municipalities and 207 counties/cities and its total area is only 42099.6 km2.The largest area for Hangju is Zhejiang province.It is concluded that the suitable area in this study completely covered the original distribution of four famous kinds of Chrysanthemum morifolium and a number of new suitable areas were found.Through further field study and experiments,these new areas have the potential to be developed into suitable production region of Chrysanthemum morifolium in the future.
