Abstract:

The research on the landscape pattern evolution of wetland has been one of the key research fields of wetland ecology.Since wetlands are ecological landscapes with abundant biodiversity，having the special ecosystem structure and function，its ecological change has been caught special attention in scientific circles.As an important natural resource，wetland offers material support for human survival and development.Profound understanding of spatialtemporal characteristics and driving mechanism of wetland change provides a basis for knowing wetland evolution rules and drawing up wetland protection policy.Through analyzing major theories，methods and achievements of domestic and foreign researches on wetland characteristics of landscape pattern in recent years，this paper explored methods and achievements on evolution of landscape pattern including landscape indices and dynamic models.It also analyzed the factors restricting researches on driving forces of wetland landscape evolution，and appraised the advantages and disadvantages of selection on driving factors and modeling them quantitatively.Based on this，it also proposed the tendency and future developing direction of the relevant studies in this field.
