Study on plant diversity in erosion gullies in Larix principis-rupprechtii plantations
Taking Larix principis-rupprechtii plantations for example ,species diversity in erosion gullies was studied in order to restore vegetation and conserve species in erosion gully in forests .The results showed that :the average species abundance inside is 13 .03 ,10 .3%lower than outside the gully .The majority of species is drought resistance and can survive at poor soils .T here is no dintinctly dominant species among them .Individual intensity is about 131 .3 per square meter ,lower than that outside the gully about 211 .6 .The uniformity index inside is 7 .8% higher than outside ,and there is no significant difference between the two species diversity index . The importance value , the abundance and the diversity of shady tolerant plant on half shady slope are higher than that on half sunny slope ,and there is no significant difference of uniformity index between the two slopes .
