Profound understanding on the diversity of local residents'willingness to pay(WTP)for ecosystem services(ESs)may aid evaluation of policy impacts by uncovering trade-offs and synergies for achieving sustainable environmental resource management.However,the reasons for the spatial preference heterogeneity of WTP are still unclear.In this study,an extensive survey with 4,580 residents in the Yangtze River Middle Reaches Megalopolis(YRMRM),central China,was carried out to investigate the public's WTP to maintain and improve ESs.We identified key influencing factors and explored how they shaped the preference heterogeneity in WTP by random forest model and surface fitting method.Our results showed that 81.4%of residents reported WTP for ESs greater than zero.Water supply,waste treatment,food supply and raw material supply were the preferred ESs for residents.Living environment factors(i.e.,extent of farmland,water and forest near the residence)were found as the key drivers of WTP.Proximity to farmland,water and forests resulted in high WTP values for a series of specific ESs.The reasons for the heterogeneity of WTP are(1)the difference in proximity to farmland,water and forest(i.e.,the contributor to ESs),(2)the divergence of local residents'preferences for ESs.This study disclosed the heterogeneity and causes of public preferences in YRMRM,which could help policy and decision makers to develop eco-compensation initiatives towards conservative and sustainable use of the environmental resources.
