The results showed that the species richness,the speciesdiversity and its biomass of understorey vegetation decreased with the stand age in-creasing.There was the most significant negative-linear relationship between thiskind of changes and age.It is possible that the certain shading condition may benefit to understorey growing better.The richness,diversity index and biomass of thevegetation in eucalypt plantation decreased with CPR increasing,however,after ro-tating by watermelon one rotation,the richness,the diversity index and biomass ofunderstorey in CP stand increased,this result will provide the possibility of therestoration and reestablishment of vegetation in eucalypt plantations.The nutrientstorage of understorey decreased in accord with the productivity decreased withCPR increasing,this is the result which the stand enviroment became worse and thestand stratum competed with the vegetation for the water and fertility of soil.

结果表明，随着年龄的增长，桉树林下植被物种丰富度降低，多样性减少，生物量下降，这种变化趋势与年龄存在极显著的负线性关系；随着造林密度的增加物种丰富度降低，多样性也下降，但林下植被生物量尚有增加，可能是一定程度的庇荫有利于桉树林下植被的生长；随连栽代次的增加，桉树林下植被丰富度降低，多样性指数下降，生物量减少；但在轮作一茬西瓜后的林地，物种丰富度提高，多样性指数升高，生物量增加，为桉树林下植被的恢复与重建提供了可能性；随连栽代次增加，林下植被养分总量逐代下降，与生产力下降一致，这是林分环境恶化后上层乔木和林下植被对水肥竞争的结果。
