Abstract:Abstract: Objective To understand the distributioncommunity composition and the botany characteristics of Pueraria lobata（Willd）Ohwi germplasm resources in Shanxi Province provides some references for the protection and sustainable utilization of resources. Methods The environment and botany properties of Pueraria lobata（Willd）Ohwi ,which were produced from the main 12 different sources in Shanxi Province wre investigated. Results They are mainly distributed in Yuncheng city ,Jincheng city and Datong city of Shanxi Province.From the point of
horizontal distribution, the range is between N34?7‘04.77‘‘～N39?1‘05.23‘‘, E110?0‘17.80‘‘～E114?3‘18.24‘‘; The vertical distribution between 730 ~ 1 240 m, with an elevation of 730 ~ 950 m is the most common. The annual rainfall of the growth area are between 400 ~ 800 mm, average annual temperature 6.8 ~ 14 ℃. The community composition is relatively single, most growth with shorter brush, only a small number with poplar, acacia trees. Depending on the ecological environment, the plant were roughly divided into three kinds of types such as savanna shrub grassland type, channel type and sandy soil type. Conclusion The germplasm resources with a wide range distribution is very abundant in Shanxi province. The differentence of ecological environment such as climate, altitude, rainfall is the most important factor to cause uneven distribution of Pueraria lobata（Willd）Ohwi in Shanxi province. The result complement and perfect the germplasm resources information .
