Abstract:

The study of characteristics of physiology and ecology and adaptability of environment has always been hot issues for many years in the domain of wetland ecology science.Due to the unique characteristics of hydrology and the gleization of soil environment,the adaptation mechanisms of wetland plant roots to surrounding environment have aroused public attentions.This paper focused on the significance of the wetland plant roots.The growth dynamics of the wetland plant roots were summarized based on the preview studies in recent years.The influenced relations and the action mechanisms of the wetland environment on the wetland plant roots were comprehensively discussed in the paper.We also investigated the influences of the impact factors in the wetland environment on the growth and physiological development of the wetland plant roots.The impact factors included hydrological process,soil moisture,soil nutrients and so on,all of which had important effects on the wetland plant roots.The roots played an important part in the wetland plant population and community.They were like a kind of transmission links that linked the material circulation and energy flow of the wetland environment and the plants.The wetland plant roots were considered as the dynamic interface between the soils and plants.The development of the roots and the surrounding wetland environment influenced each other.In the development process of the plant community,the growth and distribution and functional characteristics of the roots would be correspondingly changed as the environmental impact factors changed.The formation of the physiological and ecological adaptability of the wetland plant roots was an important manifestation of the survival ability to adapt the changes of the wetland soil environment.Strengthening the studies of the adaptive process and mechanism of the wetland soil environment on the roots could assist in grasping the dynamics change of the rhizosphere microecosystem and understanding the ecology succession and evolution of the wetland plant community
