Water Conservation Capacity of Litter and Soil in Mixed Plantation of Pinus massoniana and Broadleaved Trees

[Objective] The effect of mixed management mode of different broad-leaved species on water conservation capacity of the litter and soil in Pinus massoniana plantation was evaluated and in order to provide a scientific basis for the construction and transformation of coniferous and broad-leaved mixed forests and the improvement of hydrological function. [Method] Fi ve mixed forests of coniferous and broad-leaved trees(P. massoniana×Bretschneidera sinensis, P. massoniana× Manglietia chingi, P. massoniana × Cercidiphyllum japonicum, P. massoniana×Camellia oleifera, P. massoniana×Michelia maudiae) with almost same site conditions and forest management models selected in Longli State-Owned Forest Farm of Guizhou Province were studied, and pure P. massoniana plantation was used as the control. Field investigation and indoor test were used in combination with volume of litter stocks, contents of soil aggregates and soil organic carbon to compare the characteristics of the litter-soil layer and the changes of water h
