| 摘 要： | 采用美国进口的空气离子测量仪，在岳麓山及其周围地区，于不同时间测定了其空气负离子含量，并用相关的评价方法进行评价。其结果表明：(1)岳麓山空气负离子含量和空气清洁度，先随海拔高度的升高而增加，到150m处左右达到最大，然后又逐渐降低，发生明显的垂直变。(2)岳麓山空气负离子和空气清洁度在下雨前后明显不同，下雨后山上的空气负离子含量显著增加，空气的清洁程度也明显提高。(3)岳麓山上非景点区的空气负离子含量和空气清洁度要高于景点区。(4)不同功能区的空气负离子含量和空气清洁度差别显著，其大小依次为：河岸＞风景区＞商业广场＞办公室＞交通干线＞车站广场。

| Abstract: | With the air ions counter made in America, we measured the amount of negative air ions in Yuelu Mountain and around in different time. The result shows: (1) The amount of negative air ions and air clean degree rise gradually with height increases, getting its peak at the height of 150m, then they decrease as the height continuous increases, existing a dramatic vertical variation. (2) The amount of negative air ions and air clean degree varied greatly when it rained, the amount of negative air ions increased evidently and the air clean degree also got better after rains. (3) The amount of negative air ions and air clean degree of non beauty spot is greater than the beauty spot. (4) The amount of negative air ions and air clean degree vary dramatically in different kinds of areas, their order is: River Bank>Beauty Spot>Business Square>Office>Traffic>Bus Station. |
