Abstract: To completely understand the effects of urban ecosystems, the effects ofecosystem disservices should be considered along with the ecosystem servicesand require more research attention. In this study, we tried to betterunderstand its formation through the use of cascade flowchart andclassification systems and compare their effects with ecosystem services. It isvitally important to differentiate final and intermediate ecosystem disservicesfor understanding the negative effects of the ecosystem on human well-being.The proposed functional classification of EDS (i.e. provisioning, regulatingand cultural EDS) should also help better bridging EDS and ES studies. Inaddition, we used Beijing as a case study area to value the EDS caused by urbanecosystems and compare the findings with ES values. The results suggested thatalthough EDS caused great financial loss the potential economic gain fromecosystem services still significantly outweigh the loss. Our study only shedslight on valuating the net effects of urban ecosystems. In the future, webelieve that EDS valuation should be at least equally considered in ecosystemvaluation studies to create more comprehensive and sustainable developmentpolicies, land use proposals and management plans.
