World cultural landscape heritage (WCLH), recognized as combinations of cultural relic and natural landscape with outstanding significance and universal value, is unique in terms of differing from the human deliberate creativity of general cultural heritage and the "de-artificialization" of natural heritage. So far, the management of WCLH has become increasingly standardized. However, with the prevalence of heritage resources development activities like heritage tourism, the phenomenon of "urbanization", "commercialization", "artificialization" and other issues have gradually emerged in WCLH sites. Such that, the management issues of WCLH have turned increasingly serious, leading to intense concerns about unsustainable development of WCLH. Drawing inspirations from management effectiveness (ME) evaluation research of protected areas and acknowledging the uniqueness of WCLH, this study constructs a WCLH ME evaluation system of four general criteria (management foundation, management system, management measures and management performance), sixteen factors and thirty-four indicators. The evaluation system is applied and verified through an empirical study of five existing WCLH sites of China. The empirical results show that the ME of Chinese WCLH is at "good" level. Specifically, the management of Chinese WCLH is overall impressive in indicators of management planning making, heritage protection performance and economic performance, but shows deficiency in indicators of protection fee, management infrastructure, management assessment, management institution, social performance, etc. In the final, this study discusses the management issues of respective heritage sites so as to provide suggestions and inspirations for the development, protection and management of the sites and other cultural landscapes in China and even the world.
