| Abstract: | The one-dimensional projection values to reflect the wetland water quality status and nutrition status are calculated here by using the projection pursuit model based on genetic algorithm and considering the surface water quality standards and the nutrition status’ evaluation criteria of reservoirs and lakes,so as to reflect the environmental quality of wetland water directly.This method is applied in an instance of Hengshui Lake Wetland in Hebei.The results show that the water quality in Hengshui Lake Wetland in 2010 is Class Ⅱ,and the water is in middle and rich nutrition. |
