| 摘 要： | 在统计力学中,熵是混乱度的度量。它一方面与土壤信息出现概率有关,一方面和土壤热力学系统中的自由能有关。土壤信息在约定前提下出现概率可反映土壤整体肥力水平,土壤热力学熵则更直接地反映了土壤系统的作功能力,是高度综合的土壤肥力指标。土壤系统耗散结构从热力学机率大的状态过渡到机率小的状态,是一个不断输入能量和获得信息的过程,为土壤肥力研究另辟蹊径。

| Abstract: | In sta istical mechanics entropy is defined as the measurement of the degree of order, this idea is relevant to the appearance of probability of soil information,in other words, it is also relevant to the free energy of thermodynamic system. Under appointed conditions, the appearance of probability of soil information could reflect the total level of soil fertility, and the thermodynamic entropy could reflect the ability of a system to do work. It is a complex index of soil fertility.Soil system d(?)ssapative struture pass over from large thermodynamic probability state to minor state is a process which energy would input continuously and obtain the information. This is a new way for the study of soil fertility. |
