Abstract As a kind of biological crust, the desert algae crust plays an important role in the desertification control. The cultivation of Microcoleus vaginatus can accelerate the formation of desert algae crust. We investigated the effect of different factors on the formation of algae crust under simulated ecological environment to find the optimal ecological condition. Our results showed that: in the rapid process of the formation of algae crust, the algae crust changed similarly, and the algae reduced with the decrease of inoculum concentration and soil moisture content. Research on desert algae crust in the soil samples from different areas showed that the desert algae crust in the straw squares soil sample was the highest. In a word, our results showed that the optimal ecological conditions for the formation of algae crust are as follows: the Chla inoculum size of 10 μg·cm-2, the soil moisture content of 10% and the soil type straw squares.
