| 摘 要： | 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。

| Abstract: | The results demonstrate that the annual mean air temperature of Casuarina equisetifolia coastal shelterbelts in Hui 1an is 19.6℃,the annual mean lowest air temperature is 17.3℃ and the annual mean highest air temperature is 22.6℃,which are all lower than that outside the shelterbelts;the annual mean air temperature is>10℃ both inside and outside the shelterbelts;the accumulated temperature≥10℃ is 6990.7℃ inside the shelter belts in the whole year,accounting for 97.5% of≥5℃ accumulated temperature inside the shelterbelts;Hui 1an coastal thermal resources are quite rich and their utilizability is large;the annual mean precipitation is 1190.8mm,which mainly concentrates in Spring and Summer;and the annual mean surface temperature is 20.4℃ inside the shelterbelts,2.7℃ lower than that outside the shelterbelts and the effect of C.equisetifolia stands on the surface temperature is larger than that on the air temperature. |
