Abstract
Results of the preliminary studies of the content of light ions in air on the territory of the National Botanical Garden of Georgia are represented. Ion concentration was measured at 25 points over area 90 hectare, and also near the main waterfall at 33 points over area 1152 m2. The maps of the distribution of the content of positive and negative light ions for the territory of waterfall and Botanical Garden as a whole are make. It is obtained that the content of ions in the Botanical Garden, especially in the gorge near the River Tsavkisi and waterfalls, corresponds to hygienic levels "minimally necessary" and "optimum". In the built-on parts of Tbilisi city at this time the content of ions its corresponded to the level "less than minimally necessary". Thus, the conducted investigations revealed the new functions of Tbilisi botanical garden for the visitors: sanitation, reducing and therapeutic. It is recommended in the future in the Botanical Garden make to more detail investigate the content of ions into different seasons of year taking into account weather conditions.
