杭州湾海涂造林后气象因子动态变化

通过对杭州湾海涂造林后气象因子的变化进行的定点研究,结果表明:造林后林地内的月平均气温与未造林地上的差异不大,在冬季有一定的保温作用;在树木生长季节能明显增加空气湿度,而在冬季可适当降低空气湿度;海涂造林后在秋冬季能提高地温,春夏季能降低地温,并且能明显地降低风速;在树木生长季节林木有降低大气压作用,在树木停止生长后林木又有增加大气压作用。

Dynamics of Weather Factors of Seabeach after Forestation in Hangzhou Bay

The dynamics of the weather factors of seabeaeh after forestation in Hangzhou bay were studied in fixed point. The results showed that the trees have certainty heat preservation function in winter. The monthly mean temperature of timberland after forestation had little difference with that of unplanted land. The air humidity of planted land increased evidently in tree growing season, and that were reduced properly in winter after forestation. The ground temperature increased in autumn and winter, and which reduced in spring and summer. The wind speed reduced evidently after forestation. The atmosphere of planted land reduced in tree growing season, and which increased in tree dormant season after forestation.
