摘要
天然林林地土壤资源及特性的调查、采样、化验分析 ,获得了 64个森林类型 30 6个天然林标准地林地土壤资料 ,分析测试土壤样品 1465个 ,测定理化指标 2 6780项次。对天然林土壤剖面进行了较全面的调查和分析。研究出天然林生物因子与其土壤理化因子相关紧密。总结出天然林林地土壤粗腐殖质、有机质、氮、磷的全量及速效量的含量 ,总孔隙度、非毛管孔隙度与水文特性均是落叶阔叶林 >常绿阔叶林 >
The soil resource and character of natural forestry land was investigated,sampling and chemical analysis were carried out. 64 forest categories and data of sample from 306 forest land natural forest were obtained. 1465 samples with 26780 physical and chemical indexes of soil tested were analyzed.The profiles of soil of natural forest were investigated and analyzed completely.The relationships between the biological factors of natural forest and the physical and chemical factors of soil were colsely.The crude humus, full and fast absorbed amount of organic, N and P in the natural forest soil were calculated. The total soilpore space,non capillary porosity and hydrological characteristics all had same law:deciduous broaded leaves forest > evergreen broaded leaves forest > conifer forest.
