| Abstract: | Biological soil crusts are prevalent in arid and semiarid regions,they are the complex mixtures of cyanobacteria,green algae,phycolichens,mosses,liverworts,fungi and bacteria.In order to understand the effect of biological soil crusts(BSCs) on seed emergence and seedling growth in loess region,we conducted field surveys and studied the impact of intact crusts,broken crusts and soil on seed emergence of 4 plant species including Pinus tabulaeformis,Caragana korshinskii,Hippophae rhamnoides and Pyrus betulifo... |
