新泰市土门林场不同混交林枯落物层持水性能的研究

对新泰市土门林场7种林分的持水性能进行了研究，结果表明：枯落物总积蓄量在1.48～10.08t·hm^-2之间. 其中刺槐-麻栎混交林的最高，黄荆纯林的最小. 枯落物层的最大拦蓄量和有效拦蓄量范围分别为：0.48～2.99mm和0.39～2.47mm.二者都以刺槐麻栎混交林最高，油松纯林最低. 在0～40cm土层中的土壤含水量和土壤饱和贮水量由大到小依次为：刺槐-麻栎混交林、刺槐纯林、麻栎纯林、麻栎-油松混交林、油松-黄荆混交林、油松纯林、黄荆纯林、荒坡.

Study on the water-holding ability of the litter in different mixed forest of Tumen Plantation of Xintai

Water-holding ability of 7 types of forests in Tumen Plantation was studied. Results show that the storage capacity of litter layer of the different forests is from 1.48 to 10.08t·hm^-2. The Robinia pseudoacacia Linn. and Quecus variabilis Carr. mixed forest have the highest storage capacity and the Vitex negundo Linn. has the lowest. The largest retaining content and the effective retaining content is ranging from 0.48mm to 2.99mm and from 0.39mm to 2.47mm respectively. The largest retaining content and the largest effective retaining content of the Robinia pseudoacacia Linn. and Quecus variabilis Carr. mixed forest are the highest ones and the Pinus tabuleaformis Carr. pure forest is the lowest. The soil moisture and the saturated water storage capacity in 0～40cm soil layer are both in declining order: the Robinia pseudoacacia Linn and Quecus variabilis Carr. mixed forest, Robinia pseudoacacia Linn pure forest, Quecus variabilis Carr. pure forest, the Quecus variabilis Carr.　and Pinus tabuleaformis Carr.　mixed forest, Pinus tabulaeformis Carr. and Viex negundo mixed forest, Pinus tabulaeformis Carr. pure forest, Viex negundo pure forest， and bare field.
