Study on ecological compensation standard of wetland in Beijing

Determining wetland ecological compensation standard is the key to constructing effective wetland ecological compensation mechanism. Taking the wetland in Beijing as the research object, this paper analyzes the mechanism of wetland ecological compensation in Beijing by using Drive forces-Pressure-State-Impact-Response model（DPSIR）. Based on the questionnaire survey data, binary Logistic model and Tobit model were used to analyze the factors influencing the respondents′ compensation willingness and compensation standard, respectively. Using the conditional value method and the value of the revised wetland ecosystem service considering the time value and the stage of economic and social development, the final ecological compensation standard was determined, and policy suggestions were put forward for formulating the wetland ecological compensation mechanism in Beijing. The results show that（1） the reasonable compensation standard of wetland ecology in Beijing is 2.728×104-4.84×104 yuan hm-2 a-1.（2） The regional
