摘要
利用压力—状态—响应（PSR）模型,构建湿地可持续利用评价指标体系和评价方法,对2000-2006年东江湖湿地可持续利用进行动态评价。一次综合评价结果为：TP=0.475,TS=0.519,TR=0.374,T综=0.459,表明压力子系统内部因子比较协调,状态子系统属可持续利用初始阶段,响应子系统处于非可持续利用阶段,区域综合评价为初步协调和可持续利用初始阶段。3个时间段（2000-2002年、2003-2004年、2005-2006年）的系统综合评价值0．4〈T综〈0．5，表明东江湖湿地各时间段均属初步协调和可持续利用初始阶段。
The wetland sustainable utilization evaluation index system and evaluation method was constructed by PSR model. Dongjiang Lake Wetland sustainable utilization dynamic evaluation was conducted during 2000- 2006. The result of synthetic evaluation was TP = 0. 475, Ts = 0. 519, TR = 0. 374, Tzong = 0. 459, It showed that the inner factors harmonized for the press subsystem, state subsystem was in the sustainable utilization initial period, the response subsystem was in the unsustainable utilization period, the area synthetic evaluation were initial harmony and sustainable utilization initial period. The system synthetic evaluation values of three time period（2000--2002,2003--2004, 2005- 2006 ）were 0.4 〈 Tzong〈 0.5. The result indicated that the every time periods of the wetland were initial harmony and the beginning of sustainable utilization stages.
