浙江省丘陵土壤的抗蚀性
On antierodibility of hilly soils in Zhejiang Province:
【摘要】 土壤抗蚀性是评定土壤抗侵蚀能力的一项重要参数。本文对浙江省丘陵土壤抗蚀性指标进行了初步分析,认为> 0.25 mm 水稳性团聚体和> 0.5 mm 水稳性团聚体是反映红壤地区土壤抗蚀性较好的指标,并探讨了不同母质类型、土地利用方式和剖面深度的土壤抗蚀性的变化规律。用主成分分析和聚类分析将供试土壤按抗蚀性指标分为4 级,并建立了土壤抗蚀性分级的多指标判别模式。
【Abstract】 Soil antierodibility was an important parameter of evaluating soil resistance to erosion.This paper reported antierodibility of hilly soils in Zhejiang Province.It was found that >0.25 mm and >0.5 mm water stable aggregates could be regarded as an index to express antierodibility of soils in this area.Then changing laws of soil antierodibility with parent materials,land use and profile depth were discussed.According to analysis of principal conponents and clusters,soil antierodibility was divided into four grades and a mult index experimental model of evaluating soil antierodibility was established.
【Key words】 antierodibility; subtropics; hilly soils; water stable aggregate;
