摘要： 湿地荒漠化导致湿地提供资源和改善环境功能的丧失,使人类生存环境恶化。随着湿地荒漠化的日益加剧,必须探讨湿地荒漠化的机制,以便采取措施缓解其荒漠化进程并最终改善荒漠化湿地的生态环境。文中介绍了松嫩平原湿地荒漠化现状,探讨了湿地荒漠化成因,并提出了缓解湿地荒漠化进程的对策,对于保护和改善湿地生态环境、合理利用湿地资源具有一定的指导意义。

Abstract: The loss of wetland function to supply resources and improve ecological environment,caused by wetland desertification,led to the deterioration of human's living environment.Along with the intensification of wetland desertification day by day,the mechanism of wetland desertification must be studied in order to take measures to relax the process of wetland desertification and improve the environment of deserted wetland ultimately.In the paper,we briefed the current situation of wetland desertification in Songnen Plain,discussed the causes and put forward the countermeasures to relax wetland desertification,which have directive significance to protecting and improving ecological environment of wetland and rationally utilizing land resources.Wetland desertification is serious in Songnen Plain.The distribution area of strong and serious desertification of wetlands accounted for 14.8 percent of whole Songnen Plain.The area of fresh water wetland shrank gradually and at the same time the deserted wetland extended.The area of wetland reduced step by step,in the meantime the area of saline soil enlarged.The desertification degree of wetland intensified continuously.The latent factors of wetland desertification are the arid climate,shallow groundwater and high degree of mineralization of groundwater.The restraining factors of wetland desertification are surface flow and plants.Human's activities such as reclamation of grassland,excessive graze and construction of irrigation works and ways destroyed the surface flow and plants,leading to the wetland s desertification.The countermeasures reversing wetland's desertification are to bring into play the multi-function of irrigation works,to construct ways which have ecological meanings,to obey physical law and give up reclamation of grass,lakes and marshes in the light of local conditions,to carry out total control of livestock,to control increasing sum of population and to raise the quality of population.

Key words: Songnen Plain wetland desertification surface flow vegetation human activity
