2006年3月至2007年2月，对佳木斯绿地的空气负离子浓度和相关气象因子进行同步观测，并分析了二者的关系.结果表明：研究区空气负离子浓度的日变化和月变化较明显；清晨和午夜前后，该区空气负离子浓度较高，中午和傍晚前后，空气负离子浓度较低，最低时只有217个·cm-3；7月的空气负离子浓度（782个·cm-3）最高，12月最低（283个·cm-3）；该区空气负离子浓度以夏季最高，春、秋两季相当，冬季最低；空气负离子浓度与温度呈极显著负相关，与相对湿度、气压呈极显著正相关.
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.
