| 摘 要： | 以棕榈科植物群落为研究对象,通过研究不同结构群落的空气正负离子浓度的动态变化,探讨空气离子浓度时空变化规律。结果表明,棕榈科群落正、负离子浓度夏季>秋季>春季>冬季,7月正、负离子浓度达到最高值,分别为1 046 lons/cm3、1 089 lons/cm3;12月正、负离子浓度最低,分别为444 lons/cm3、455 lons/cm3,不同季节空气离子浓度的日变化均存在一定的差异。不同结构棕榈群落空气负离子浓度及空气质量等级的顺序为:乔灌草型群落>乔草型群落>乔灌型群落>对照地。

| Abstract: | To determine the law of spatio-temporal changes of aero-cation and aero-anion,the concentration of aero-cation and aero-anion of the different structure of Palmae community were measured.The results showed that the order of aero-cation and aero-anion was as follows:summer>autumn>spring>winter.The highest concentration of aero-cation and aero-anion,appeared in July,were 1 046 lons/cm3,1 089 lons/cm3 and the lowest in December were 444 lons/cm3,455 lons/cm3,respectively.There were some differences in the diur... |
