The Research Trends of Ecosystem Services and the Paradigm in Geography

As studies on ecosystem services are becoming a hot spot among scientists,a research paradigm needs to be built in related discipline fields such as geography.This paper reviewed the progress,problems and trends of studies on ecosystem services at home and abroad.Furthermore,aiming at the topics and problems in current ecosystem service studies, we proposed a geographical paradigm and priority themes in this field.It is suggested that spatial heterogeneity and regional difference should be taken as entry points to study ecosystem services from geographical perspectives.Researches should be focused on the theme of ecosystem structure and function-ecosystem services-human well-being,and take the coupling connections between"ecosystem services offered by natural system and then internalized consumption of socioeconomic system"as the core research theme for comprehensive analysis of the response of socioeconomic system to the internalization of natural capital.We can promote integrated research on geographical sciences by constructing the geographical study paradigm of ecosystem service,which can not only expand the study capacity for ecosystem services,but also raise the level of comprehensive studies on social-ecological system.In addition,we should offer an important practical field for the study of human-land relationship,which is the core issue of geography.
