选择了甘肃省7个代表性林区,利用ITC-201A型智能便携式空气负离子测定仪对14种林分类型的空气负离子浓度进行了为期2年的测定与研究.结果显示:①森林空气负离子浓度针叶树种均值为578 cm-3,阔叶树种均值为471 cm-3;针叶混交林为722 cm-3,针阔混交林为661 cm-3,阔叶混交林为492 cm-3;不同植被类型均值表现为:针叶混交林＞针阔混交林＞针叶树种＞阔叶混交林＞阔叶树种;②各森林区空气负离子浓度铁杉为最大(877 cm-3),冷杉为最小(372 cm-3),14种林分类型表现为:铁杉(Tsuga chinensis(Franch.)Pritz)＞针叶混交林(coniferous mixed forest)＞云杉(Picea crassifolia Kom.)＞针阔混交林(Mixed needle)＞华山松(Pinus armandii Franch.)＞落叶松(Larix gmelinii(Ruprecht)Kuzeneva)＞桦木(Betulasp.)＞杨树(Populussp.)＞油松(Pinus tabulaeformis Carr.)＞阔叶混交林(broadleaf mixed forest)＞栎类(Quercus)＞柏木(Cupressus funebris Endl.)＞椴树(Tilia tuan Szyszyl.)＞冷杉(Abies fabri(Mast.)Craib);③空气负离子浓度与温度成负相关,相关性方程为y=-57.457x+1 486.2(R2=0.910 5),与空气相对湿度成正相关,相关性方程为y=9.348 5x-103.57(R2=0.680 1).
