| 摘要: |
| 对4块7年生杉木优良家系区域化测定试验林进行了实测调查与统计分析，结果表明：家系间胸径、单株材积有极显著差异，3个生长性状在地点间差异极显著，在家系×地点互作上表现为互作效应极显著，各家系生长存在遗传差异，不同家系对造林立地适应性有所不同，立地不同林分生长也不一样，说明开展区域试验是必要的。本文根据单株材积主效应、家系×地点互作效应及变异系数的统计结果，13个家系可分为速生稳定型、速生变化型、慢生稳定型和慢生变化型四种类型，对各类型家系作了应用评价。 |

| Abstract: |
| The regionalization test of 4 fine families plantation of 7 years old Cunninghamia lanceolata. The results showed that the increments of DBH and volume were found to be significant different in families. There were extremely significant different in 3 Growth Character in site and family×site interaction effect were significant different. In families, there were genetic difference. It is different families’ adaptability that due to different reforestation site. To hold test is necessary. According to the main effect of plant volume, family×site interaction effect and the coefficient of genetic variation, 13 families were divided into Fast-growing stable type, Fast-growing unstable type ,slow-growing stable type and slow-growing unstable type. |
