Abstract: Microclimate was monitored in 2012 by 15 sample plots with different rocky desertification degrees in the Huajiang Gorge area, which is a Karst plateau gorge moderate-strong rocky desertification area located in middle stream of Beipan river. Using the method of space instead of time, this paper analysed the environment factor changes in the process of rocky desertification. The results showed that microclimate factors and soil water content varied in different rocky desertification degrees, and microclimate quality of N displayed the best. With the increase of rocky desertification degree,most environmental factors showed a process of improvement after degradation rather than lining decrease. Microclimate quality of L and SL displayed not very well and disordered in seasons due to frequent human disturbance. Some microclimate effects in ST and M started rehabilitation and whole habitat became healthy and orderly development resulted from constant comprehensive treatment and less human disturbance.
