摘要/Abstract

摘要： 借助功能生态学的理论,提出了运用土壤的特征物质(CM)和特征时间(CT)区分土壤类型的新方法。通过数学模拟,分别计算了灰色森林土和黑钙土的特征物质和特征时间 :当灰色森林土和黑钙土的年凋落物量分别为 5.5t·hm^-2 和 11.2t·hm^-2 时,它们的CM和CT分别为 133t·hm^-2 、80年和 820t·hm^-2 、650年。CM和CT的值随着输入土壤的物质量和土壤中分解速度的变化而变化,而且受外界环境因素(包括自然因素和人为因素)的影响。CT随土壤深度的增加而增大

Abstract: Based on the theory of functional ecology, a new method for distinguishing soil types according to its characteristic mass(CM)and characteristic time(CT)was presented. By mathematical modeling, the CM and CT of Soddy-podzodsand Cherro zem was calculated as the orders of 133 t穐m^-2 and 80 years with an annual litter-fall mass about 5.5 t穐m^-2 for Soddy podzods, and 820 t穐m^-2, 650 years with an annual litter-fall mass 11.2 t穐m^-2 for the Cherro zem. Further more, the CM and CT varied with the change of mass input and decomposed velocity in the soil, which are influenced by the external factors(light, temperature, moisture etc.)and anthropologic factors. We also found that the lower the horizon was, the longer the CT would be.

Key words: Runoff plot, Transport parameters, Spatial variability
