| 摘 要： | 该文以1995年造林的针阔混交林为研究对象,对15a生的针阔混交林的林下凋落物持水能力和养分状况进行了调查和分析。结果表明:混交林比纯林具有更好的保水保肥的能力;混交林中林下凋落物饱和含水量以杉木×枫香(1∶3)最大,枫香×鹅掌楸(1∶3)最小;混交林中凋落物量以鹅掌楸×杉木(1∶1)混交林最大,枫香×鹅掌楸(1∶3)混交林的凋落物量最小。

| Abstract: | Taking the mixed forest planted in 1995 as the research object,the water-holding capacity and nutrient status of forest floor litter in a 15-year mixed forest were investigated and analyzed. The results indicated that:com-pared to pure forest,mixed forest had a better capacity in keeping water and fertilizer;mixed forest Cunninghamia lanceolata and Liquidambar formosana(1:3)had the highest saturated water content while mixed forest Liquidambar formosana and Liriodendron Chinese(1:3)was the lowest;mixed forest Liriodendron Chinese and Cunninghamia lan-ceolata(1:1)had the largest amount of litter fall while mixed forest Liquidambar formosana and Liriodendron Chinese (1:3)had the smallest. |
