【Abstract】 In order to conduct an effective management over the existing forest resources,the resin yield forecast models of Pinus elliottii and the data table were studied,taking,as the researching objects,Pinuselliottii forests with tree diameter of above13 cm in Sanfang forest station of Ji’ an County,Forestry Science Research Institute of Ji’ an County,Shuangcun forestry station of Jishui County,Luxiling foreststation and Forest Science Research Institute of Ji’ an City. The results show thatthe models have good fitting effects with stability.更多还原
