| Abstract: | Objective] The study aimed at assessing the whole value of Qilihai Wetland in Tianjin City.Method] In this study,the whole value of Qilihai Wetland was divided into two parts,namely use value and non-use value.The use value of Qilihai Wetland was estimated by market value,travel cost,shadow project method and so forth,and the non-use value of Qilihai Wetland was assessed by contingent valuation method.Result] The total value of Qilihai Wetland reached 1.892 billion yuan,wherein the direct use value,including animal and plant products,tourism,scientific and cultural value,was 0.539 billion yuan,accounting for 28% of total value;the indirect use value,composed of functional values in hydrology,water quality,erosion control,CO2 fixation and habitat,was up to 0.965 billion yuan,making up 51%;the non-use value totaled 0.388 billion yuan,taking up 21%.In addition,the ecological benefit of Qilihai Wetland was the maximum,accounting for 72% of total benefit,followed by economic benefit(21%),while the social benefit was the minimum(9%).Conclusion] The results can provide scientific references for the effective conservation and sustainable utilization of Qilihai Wetland. |
