对惠安木麻黄沿海防护林的小气候进行了定位观测。其结果为 :惠安木麻黄沿海防护林内年平均气温为 19 6℃ ,年平均最低气温为 17 3℃ ,年平均最高气温为 2 2 6℃ ,均比林外低 ;木麻黄林内外年平均气温均 >10℃ ;全年林内≥ 10℃的积温 6 990 7℃ ,占≥ 5℃林内积温的 97 5 % ,惠安沿海热量资源很丰富 ,可利用性大 ;年平均降水量为 1190 8mm ,降水主要集中春夏两季 ,冬秋季降水少 ,10月、11月份林分干旱 ;木麻黄林年平均地面温度为 2 0 4℃ ,比林外低 2 7℃ ,木麻黄林分对地温的影响比气温大。
Huimu Casuarina coastal shelterbelt Microclimate positioning observation. The results are as follows: The mean annual temperature of Casuarina equisetifolia in Hui’an was 19 6 ℃, the annual average minimum temperature was 17 3 ℃, and the annual average maximum temperature was 226 ℃, both lower than that of the forest; The average accumulated temperature of ≥ 10 ℃ in the forest was 6 990 7 ℃, accounting for 97.5% of the accumulated temperature in the forest. The coastal Huai’an coastal area was rich in heat resources and available for use. The average annual precipitation was 1190 8mm, precipitation Mainly concentrated in spring and summer, less precipitation in winter and autumn, and aridity in October and November. The mean annual surface temperature of Casuarina equisetifolia was 204 ℃, and the lower than the forest was 27 ℃. The effect of Casuarina equisetifolia on soil temperature Greater than the temperature.
