To investigate the spatio-temporal variations, influential factors and environmental health effects of negative air ions (NAIs) in Hainan tropical rainforests, a mobile comprehensive measurement platform was utilized to carry out field observation during typical tourist season (January), four types of typical forest stands (evergreen broad-leaved, deciduous broad-leaved, coniferous and bamboo forests) at eleven different altitudes in the Wuzhishan area of the Hainan Tropical Rainforest National Park were measured. The concentrations, spatiotemporal variations of NAIs, and their relationships with forest types, meteorological factors, air quality, and volatile organic compounds (VOCs) were analyzed. A comprehensive evaluation method for the ecological health function of tropical rainforest based on the Forest Health Index (FHI) was established. The results showed that the NAI concentration in the Wuzhishan area was relatively high (3541±882) moles/cm3, reaching Level VI of the World Health Organization's air freshness classification standard. The NAI concentration was increased with altitude initially and then decreased. Coniferous forest was found to have the highest NAI concentration, followed by broad-leaved forest, with bamboo forest having the lowest. A total of 66VOCs were detected, with sesquiterpenes and oxygenated organic compounds accounting for over 80%. NAIs were shown significant positive correlations with relative humidity, fine particulate matter, and monoterpenes, and significant negative correlations with sesquiterpenes and aromatic hydrocarbons. The FHI in the afternoon was generally found to be higher than that in the morning, with most sampling sites reaching Level II or above.
