一、相关计算的概念、意义及其在土壤学中应用的现状自然界中的各种现象并不是孤立的,而是彼此之间存在着一定的联系.在土壤学中,某些成土条件之间、某些土壤性质之间、成土条件与土壤性质之间都存在着一定的联系.例如地区的降水量与土壤中化合物的淋洗深度之间、干旱区地下水的深度与土壤的盐渍度之间、每年进入土壤的有机残体的数量与腐殖质含量之间、腐殖质含量与吸收量之间……都存在着依存关系.事实上,在更多的情况下,自然界中的各种现象,其出现过程都要同时受许多因素的制约.
First, the concept of the relevant calculation, meaning and its status in the application of soil science The phenomena in nature are not isolated, but there is a certain relationship between each other in soil science, some soil conditions Some soil properties, soil conditions and soil properties are some connection between, for example, between the regional precipitation and the depth of compound leaching in soil, the depth of groundwater in arid areas and soil salinization Degrees, there is a dependency between the amount of organic residues entering the soil and the amount of humus, the amount of humus and the amount of uptake each year ... In fact, in more cases, various phenomena in nature , Its emergence process should be subject to many factors at the same time.
