Abstract:Based on the basic principle of AHP,the index system of eco-environmental quality appraisal of Yellow River Delta wetland was built in this study.The improved AHP method was used to determine the wEight of each appraisal index,and consequently to determine the main factors,secondary factors,and general factors which have impacts on the eco-environment of Yellow River Delta wetland.The results showed that the flood regulation function of the delta had been highly emphasized by the sectors concerned while the climate regulation function of the delta had recEIved little attention,which could provide some references for the landscape planning,management and protection of the Yellow River Delta wetland.
