Abstract: Sustainable utilization is now being considered as a leading thought and a common principle in regard to ecological system of wetland.The environment problem in wetland utilization has also seriously affected the equilibrium of related regional ecosystem.It is intended to provide a systematic pathway to find a reasonable measure for sustainable utilization of wetland in Lixiahe region.The present utilization of wetland has resulted in some serious environment problems in the region,including shrinkage of the area of wetland,frequent natural disasters,deterioration of the environment,serious pollution caused by production and domestic life,degradation of wetland in function,decline in benefit of agricultural production and resultant decrease in farmers′ production input.For keeping the equilibrium of ecological system of wetland,the following strategies for sustainable utilization of wetland in the study area are put forward in light of the above problems:1)establish new indexes and standards for evaluation of sustainable utilization; 2)establish an early warning and analysis system; 3)increase overall comprehensive social,economic and environmental benefits,based on modern wetland ecological engineering technique.
