摘要
国外对土壤结皮的研究历史可分为两个阶段:第一,定性描述阶段;第二,半定量研究阶段。国内对土壤结皮的研究起步较晚,目前研究主要停留在定性描述的基础上,定量研究其理化性质、形成过程特征及对土壤侵蚀和农业生产的影响都是噬待解决的问题,研究的深度和广度均需拓展。
National research on soil crust could be divided into two stages. The first stage was characterized by qualitative description. The second stage was characterized by semi-quantitative research. The start of domestic soil crust research was late, and the research of soil crust was mainly focused on qualitative description. Quantitative research on its properties was essential, such as physicaland chemical properties, development, its influence on soil erosion and agriculture. So, further studies need to do deeply and widely.
