摘　　要：采用相关分析和典型相关分析方法，对油菜低产林改造中各效应因于间及其与产量间的相关关系进行分析，表明：叶绿素含量、叶片中磷含量、单株果数、地面相对光强和土壤容重与产量关系密切；生态效应因子是通过影响生长效应因子，生长效应因子又是通过影响结实效应因子，进而影响油茶产量的。还采用灰色局势决策方法，对低改措施组合进行决策，结果是综合改造效应最显著，增产最明显。ABSTRACT An analysis was conducted between the ecologic. economic and social effects ofthe stand improvement test. using correlation analysis and canonical correlation analysis. Results showed that the fruit yield was closely related to the content of chlorophyll. the con-tent of phosphorus in the leaf. the number of fruit of each individual tree. the relativeground light intensity. and the bulk density of water immersed soil．It was also revealed thatthe yield of fruit was affected by the ecologic factors whichin turn imposed an impact on thegrowth and fruiting performance of the tree. Meanwhile. the various improvement treat-ments were optimized with the game theory of grey events. indicating that the integratedtreatment was the best choice in that it resulted in the greatest increase in fruit yield.
