Perspectives for Future Studies on Greenspace and Health in China

We have performed systematic summary on studies concerning greenspace and human health in Chinese population. We also reviewed evidence on greenspace exposure assessment, potential mechanisms, and urban greening polices. The existing evidence suggest that the studies related greenspace and health remain limited in China, and many of the explored associations were inconclusive. In addition, the underlying mechanisms by which greenspace affects health remain not very clear. Thus, our recommendations on future studies included: (1) more studies on each topics are needed; (2) prospective cohort studies and intervention studies should be performed to validate the associations on greenspace and health and to differ which kind of greenspace act on health; (3) more accurate and dynamic exposure assessment; (4) fitting non-linear relationship; and (5) exploring new mechanisms.
