Abstract: This paper used daily relative humidity data measured at two meteorological observing stations (an urban site and an open site in the urban forest) during the period of 16 years. The results showed that the annual course and abnormal phenomena of air humidity (i. e. RH) etc. in the urban forest area obeyed the local macroelimate law. The annual mean of the RH in the urban forest site was 2.2 more than that in urban site. The RH difference between two site was distinct, when the RH was minimum at daytime. The urban forest played an important role in supplemental air moisture near the adjacent space.
