The purpose of this study is to reveal the ecological restoration effect of Benggang in the process of vegetation natural restoration and the adaptation mechanism of plants to the harsh environment. Taking 3 Benggangs in Huangnikeng,Zhuotian Town,Changting County of Fujian Province representing 3 different active situations(active,semi-stable,and stable)as the study cases,we analyzed the ecological stoichiometric characteristics and correlations of soil and plant nutrient content under the process of natural vegetation restoration by using ecological stoichiometric methods. The results showed that the soil nutrients in different parts of collapse wall were significantly different(p<0.05); the stable Benggang's soil organic C,total N and total P contents were the highest in the 3 Benggangs,but they were only up to 3.88 g/kg,0.44 g/kg,0.06 g/kg,which were far below the national level; the contents of C,N,P in Dicranopteris pedata were significantly different(p<0.05); however,the correlations between C,N and P contents in plants and those in soil surface were not very relevant(p>0.05). It can be concluded that with the increase of vegetation coverage,the activity of Benggang gradually stabilized and the soil fertility could be improved but only be at the low level. Additionally,the Dicranopteris pedata nutrient was not mainly determined by soil nutrient,but mainly affected by the characteristics of the plant itself,which showed the adaptability of the plant to the extremely degraded ecosystem environment and could be used as an important measure to improve soil fertility of Benggang system in red soil erosion area of southern China.
