From six aspects of the physiognomy,lithology,soil,groundwater circulation,creature and climate,this paper probes into the action mechanism and feedback mechanism of the underground water and soil loss on the ecological restoration.
从地质地貌、岩性、土壤、地下水循环、生物、气候6个方面探讨了地下水土流失对生态恢复的作用机理和反馈机制。
The mechanism of soil and water loss underground in karst region involves many fields and has internal relevance with the mechanism of rock-soil-water-organism underground.
