摘要
生物土壤结皮在荒漠化地区广泛分布。本文详细论述了生物土壤结皮的分布规律及其影响因素 ,如海拔高度、土壤、维管植物群落水分条件和干扰 ,以及生物土壤结皮在生态系统和景观变化监测和评价中的作用等。
Biological soil crust exists in desertification prone areas.This paper focuses on the concept of crusts,distribution and factors influencing species composition,and its monitoring for assessment of ecosystem and landscape change.Some preliminary suggestions were given for further understanding the relationship between biological soil crust and ecosystem or landscape in desertification prone areas in north western China.
