Abstract:This paper deals with the composition,morphological characteristics and dimentional distribution of root system in alder and cypress mixed plantation. The stand biomass and productivities, nitrogen accumulation and its distribution of root system have also been compared in different types of forests. The results show that the biomass,composition, morphology and distribution of root system of different species and different stands vary significantly.In the mixed forest,the root system of alder trees grow usu...
