| 摘 要： | 对福建省尤溪县包溪林业采育场1974年营造的杉木毛竹混交林水源涵养能力和经济效益进行了研究。结果表明: 杉木密度为1 350株 hm- 2的混交林涵养水源能力最强,林冠层持水量比杉木纯林多0. 545 t hm- 2 , 比毛竹纯林多3. 049 thm- 2; 地上部分总持水量( 25. 424 t hm- 2 )分别比杉木纯林、毛竹纯林增加3. 143 t hm- 2 , 3. 309 t hm- 2 ; 土壤( 0～ 40 cm层)贮水量达611. 2 t hm- 2 ,比杉木纯林、毛竹纯林和其他混交林都大; 初渗值达60. 86 mm min- 1 ,稳渗值达24. 32 mmmin- 1 ,分别是杉木纯林2. 8倍和2. 3倍,毛竹纯林的2. 5倍和1. 6倍。

| Abstract: | The research was made at Baoxi Forest Farm of Youxi County, Fujian Province. The mixed forest with Chinese fir ( Cunninghamia lanceolata ) and moso bamboo( Phyllostachys pubescens) was established in 1974. The results showed that mixed forest with the density of 1 350 plants per hectare for Chinese fir had the strongest function of water conservation. The water-holding content in canopy of mixed forest was 0. 545 t hm- 2 more than pure Chinese fir, and was 3. 143t hm- 2 more than pure moso. Total water-holding above ground part reached to 25. 424 t hm- 2 , 3. 143 t hm- 2 and 3. 309 t hm- 2 more than pure Chinese fir and pure moso respectively. Total water-storing of soil at 0～ 40 cm was 611. 2 t hm- 2 , larger than pure Chinese fir, pure moso and other mixed forests. Initial infiltration and stable infiltration capacities were 60. 86 mm min- 1 and 24. 32 mm min- 1 , which were 2. 8 times and 2. 3 times for pure Chinese fir, and 2. 5 times and 1. 6 times for pure moso stand, respectively. |
