摘要
应用多指标评分法和层次分析法对杉木一代种子园无性系进行综合定量分析，选择出供二代种子园建园使用的优良无性系15个，并指出了洋19等15个劣质无性系应在生产过程中结合间伐逐步淘汰，为当代种子园生产经营管理提供科学依据．
In this paper,45 Chinese Fir Clones chosen from the first generation seed garden have been analysed multi-targetly，using the method of synthetic decision of multitarget-gradation analysis．Then 15 fine Chinese fir Clones have been selected for building the second generation seed garden,which were YK21,JY36,GP9,SM58,SM21,JY10,SM14,SM67,SM52,YK23,YK3,YK47,YK28,SM45,YK27;and it pointed out that 15 bad clones such as YK19.eg must be eliminate during their thinning.This study could provide scientific basis for provide scientific basis for production management of seed garden．
