[Air negative ion concentration and its relationships with meteorological factors in greenbelts of Jiamusi, Heilongjiang Province].
From March 2006 to February 2007, a synchronous observation was conducted on the air negative ion concentration and related meteorological factors in the greenbelts of Jiamusi, with their relationships studied. There was an obvious diurnal and monthly Variation in the air negative ion concentration, being higher in early morning and midnight and lower in mid-day and late afternoon, with the minimum of 217 ions per cubic centimeter, and being the highest in summer and the lowest in winter, with the maximum (782 ions per cubic centimeter) in July and the minimum (283 ions per cubic centimeter) in December. The air negative ion concentration was significantly negatively correlated with air temperature, and positively correlated with air pressure and relative humidity.
