摘    要:分析了浙江安吉主要植被类型土壤水库总库容、最大有效库容、滞洪库容、兴利库容、死库容等特性及差异,并对影响土壤最大有效库容的因素进行了探讨。结果表明:安吉地区不同植被类型土壤水库容状况有较大差异。灌木林、落叶阔叶林土壤具有较高的总库容、兴利库容、滞洪库容和最大有效库容,表现出较强的贮水能力。裸露地土壤死库容最高,而其他土壤水库容指标都要显著低于有植被覆盖的样地。土壤理化性质、≤1mm细根显著地影响着土壤的最大有效库容。根系及土壤理化性质对土壤最大有效库容的影响,最终是通过改变土壤的孔隙状况来实现的。

关 键 词:土壤水库  植被类型  库容特性  土壤理化性质

Abstract:It is studied the characteristics and differences of soil reservoir total capacity, maximum available capacity, flood control capacity, storage capacity and dead capacity in the main forest types in Anji county of Zhejiang province, and discussed the factors that control the maximum effective storage of soil reservoirs. The results show that there are great differences in soil reservoir capacity of various plots. The soil reservoir total capacity, storage capacity, flood control capacity and the maximal available water capacity of deciduous broad - leaved forest and shrub community were high, which was helpful to reduce surface runoff. The dead capacity of the bare land was the highest and the water - holding function was the poorest. Soil physicochemical properties and the roots, especially roots less than lmm in di- ameter have the obvious impact on the effective improvement of maximal soil reservoir capacity. The impact of roots and soil physicochemical properties to the maximal soil reservoir capacity are finally realized through the change of pore space of soil.
Keywords:soil reservoirs  vegetation type  reservoir capacity characteristics  soil physicochemical properties
