The spatial attribute of willingness to pay is one of the main factors affecting the valuation validity of environmental goods, and ignoring the consideration of spatial distance may lead to bias in the monetary valuation of the resource environmental goods or services. This paper takes the Enteromorpha prolifera in Qingdao sea area as the research object, uses the contingent valuation method, constructs the willingness-to-pay function model, measures the distance of respondents from Qingdao city seashore, and explores whether there is a distance decay phenomenon in the willingness to pay for Enteromorpha prolifera management; this paper measures the public willingness to pay for Enteromorpha prolifera management in different distance zones by dividing them into different distance zones, and aggregates them to obtain the total economic value of Enteromorpha prolifera management. The results show that: the willingness to pay for the management of Enteromorpha prolifera is obviously distance decay, and the public closer to the seashore tends to pay higher; the total economic value of Enteromorpha prolifera management in Qingdao is 984 million yuan/year; disregarding thedistance decay effect will eventually lead to an overestimation of the economic value of Enteromorpha prolifera management by up to 27.03%. The findings of the study can provide new research ideas and scientific references for non-market value assessment at the spatial scale, which not only improves the validity of the valuation results of the contingent valuation method, but also provides a more accurate economic value of Enteromorpha prolifera management in Qingdao. |
