- Title:
- Study on Water Capacity of Litter in Different Forest Distribution of Sanlizhuang Reservoir
- Keywords:
- litterfall; water-holding ability; water capacity

- 摘要:
- 通过对诸城市三里庄水库上游的刺槐林、麻栎林、油松林、刺槐麻栎混交林等主要林分类型的枯落物现存量及其持水性能的研究，总结出不同林分类型的枯落物的持水特征。结果表明枯落物的积蓄量为刺槐林>刺槐麻栎混交林>麻栎林>油松林，枯落物的最大持水量为刺槐林>刺槐麻栎混交林>麻栎林>油松林，枯落物的有效拦蓄量为刺槐林>刺槐麻栎混交林>麻栎林>油松林，研究结果还表明，枯落物的粗糙度越大，截留径流的能力也越强，枯落物的水容量越大。
- Abstract:
- The litter biomass and its water capacity are studied on the main forest types, Robinia pseudoacacia Linn forest, Quercus acutissima Carr forest, Pinus tabulaeformis Garr forest, Robinia pseudoacacia Linn and Quercus acutissima Carr forest etc in Sanlizhuang reservoir of Zhucheng City, the biomass max water capacity and decomposition rate are sorted on different forest types. The study result shows that litter amount is Robinia pseudoacacia Linn>Robinia pseudoacacia Linn and Quercus acutissima Carr>Quercus acutissima Carr>Pinus tabulaeformis Garr, the largest water-holding is Robinia pseudoacacia Linn>Robinia pseudoacacia Linn and Quercus acutissima Carr>Quercus acutissima Carr>Pinus tabulaeformis Garr, the water effective intercept capacity of the litter is Robinia pseudoacacia Linn>Robinia pseudoacacia Linn and Quercus acutissima Carr>Quercus acutissima Carr Pinus tabulaeformis Garr, so the result shows that the more litter surface roughness is, the larger the water capacityis.
