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１３５０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０．５４５ｔ·ｈｍ－２，比毛竹纯林多３．０４９ｔ·ｈｍ－２；地上部分总持水量（２５．４２４ｔ·ｈｍ－２）分别比杉木纯林、毛竹纯林增加３．１４３ｔ·ｈｍ－２，３．３０９ｔ·ｈｍ－２；土壤（０～４０ｃｍ层）贮水量达６１１．２ｔ·ｈｍ－２，比杉木纯林、毛竹纯林和其他混交林都大；初渗值达６０．８６ｍｍ·ｍｉｎ－１，稳渗值达２４．３２ｍｍ·ｍｉｎ－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。
The water conservation ability and economic benefits of the mixed plantation of Cunninghamia lanceolata and Phyllostachys heterocycla cork in 1974 were studied in BaoXi forestry mining farm in Youxi County, Fujian Province. The results showed that the mixed forest with fir density of 1350 plants · hm-2 had the highest water conservation capacity, the water holding capacity of canopy layer was 0.545 t · hm-2 more than that of pure Chinese fir plantation, 3.049 t · hm-2 more than that of pure plantation (25.424t · hm-2) increased 3.143t · hm-2 and 3.309t · hm-2 respectively in pure Chinese fir plantation and pure-stand plantation of bamboo forest, while that in 0-40cm soil layer Up to 611.2t · hm-2, which was higher than that of pure Chinese fir, pure bamboo and mixed forest. The initial permeability reached 60.86mm · min-1 and the infiltration stability reached 24.32mm · min-1 Chinese fir forest 2.8 times and 2.3 times, pure bamboo forest 2.5 times and 1.6 times.
