摘　　要：采用五点法对宜宾市分布较多的4种竹资源,硬头黄竹、撑绿竹、慈竹和绵竹不同生育期的鲜重、总鲜重和经济效益分析,结果表明:1)不同竹种总鲜重平均大小为慈竹>撑绿竹>绵竹>硬头黄竹,不同生育期鲜重平均大小为1a生竹>2a生竹>多年生竹;2)不同生育期竹鲜重与总鲜重相关程度较高,绵竹总鲜重与2a生竹鲜重极显著相关,相关系数为0.943;3)不同竹种经济效益表现为慈竹>绵竹≈硬头黄竹>撑绿竹,撑绿竹1a生阶段经济效益比例高达44.58%,多年生阶段经济效益所占比例最小为22.78%。Based on the five point method,four species of bamboo which are widely distributed in Yibin named Bambusa rigida,Bambusa pervariabilis,Neosinocalamus affinis and Bambusa intermedia were investigated. According to the fresh weight,total fresh weight and economic benefit analysis,the conclusions were drawn as follows: 1) The mean total fresh weight of the four species of bamboo was presented as: Neosinocalamus affinis > Bambusa pervariabilis > Bambusa intermedia > Bambusa rigida. When the fresh weight of different stages annual,biennial and perennial one were compared,the annual bamboo fresh weigh was at the highest while the perennial was the lowest. 2) The total fresh weight and the different stage fresh weight showed highly correlation where the total fresh weight and the biennial weight of Bambusa intermedia presented the significant correlation with the correlation coefficient 0. 943. 3) The economic benefit result showed that the Neosinocalamus affinis was the best,and the Bambusa pervariabilis was not economical. The other two species of bamboo were at almost the same condition. Further analysis showed that the economic benefit ratio of the annual Bambusa pervariabilis was as high as 44. 58%,and the perennial stage accounted for the smallest proportion 22. 78%.
