【摘要】：土壤裂隙的发育是土壤自身内在属性在外界条件变化时综合作用的结果,与土壤物理、化学及生物性质息息相关,对农田水肥蓄积、坡体稳定、地下水污染等的危害很大。本文首先阐释了土壤裂隙的内涵及其与孔隙之间的区别与联系,而后从形成机制的角度对土壤裂隙进行了分类,并归纳总结了水平裂隙和垂直裂隙的描述方式及裂隙的评价指标体系,接着对干缩裂隙发育的外因及内因做了较深入的讨论,最后对土壤裂隙日后研究工作的重点提出了建议,旨在为土壤裂隙研究提供有益借鉴。
[Abstract]:The development of soil fissures is the result of the comprehensive action of the inherent properties of soil when the external conditions change, which are closely related to the physical, chemical and biological properties of soil, and are harmful to the accumulation of farmland water and fertilizer, the stability of slope body, the pollution of groundwater, and so on. In this paper, the connotation of soil fissures and the difference and relation between soil fissures and pores are explained, and then the soil fissures are classified from the angle of formation mechanism. The description mode of horizontal and vertical fractures and the evaluation index system of fractures are summarized, then the external and internal causes of the development of dry-shrinkage fractures are discussed in depth, and some suggestions for the future research work of soil fissures are put forward. The purpose is to provide useful reference for the study of soil fissures.
