The Value of Naturalness of Urban Green Spaces: Evidence from a Discrete Choice Experiment
通过在线调查和离散选择实验，发现德国居民每月愿意支付20.25欧元，用于将最近城市绿地的自然性提高一个等级。
<h3>ABSTRACT</h3> The range of benefits for humans and biodiversity conservation provided by urban green spaces (UGS) receives substantial attention in relation to urban planning and management. However, little is known about the value of nature in UGS. We developed a graphical measurement scale for the naturalness of UGS, with 5 steps between largely sealed and largely wilderness, which was embedded in an online survey and a discrete choice experiment. Using mixed logit models, we find that German citizens have a mean willingness to pay of €20.25 per month for an increase in the naturalness of the closest UGS by one step.
