英文摘要Negative air ion concentrations (NAIC) are being used as a significant indicator of air quality in urban life. Generally, the NAIC over unpaved areas, e.g., meadows, fields, in cities is around several hundred ions/cm(3), which is not high enough to promote human health. In this study, to increase the outdoor NAIC over urban lawns, research was carried out on the biogeneration of negative air ions with lawn grasses by adjusting discharge of kV electricity under different conditions. The results showed that lawn grasses with gladiate, lanceolate or angustifoliate leaves stimulated by kV electricity, generated high NAIC predominantly from the leaf tips at the order of 1E6 ions/cm(3). The discharges could be divided into continuous and discontinuous discharge according to the voltage of the kV electricity. Different substrates, including soil, pearl, salt and sand were all suitable for exposure to the different discharges. Moreover, when NAIC was maintained at a high level, the positive air ion concentration decreased with an increase of the planting densities of grass. After discontinuous discharge, normal growth of the lawn grasses, including superoxide dismutase activity and chlorophyll content were not significantly influenced.
