摘要
根据生态学原理，把天然更新和人工改造更新相结合，对光泽县林业试验场残次天然阔叶林进行改造，通过改造可很快地形成多树种的混交林，林木材积提高１１４．６％～２１８．６％，土壤物理性质比杉木纯林好，土壤蓄水量比杉木纯林提高８０．７％～９１．５％，有良好的生态经济效益，实践证明，残次天然阔叶林改造是加速培育森林资源的好途径。
Through the remake,the mixed forests with many species could be quite rapidly formed,the forest tree volume increased by 11462186%,the soil physical property was better than that of pure forests of Cunninghamia lanceolata,the soil water storage capacity increased by 807915% as compared with pure forests of C.lanceolata and the ecological and economic benefits were good.The practice proves that remaking the residual secondary natural broadleaved forests is a good way to quicken the culture of forest resourses.
