补充资料:森林气候
森林气候 forest climate 森林地区的局地气候。由林区地理位置、环境条件、面积大小、地形特点、林木种类、林型结构等综合影响形成。广义则指地球上森林地带的气候类型,包括热带雨林气候、亚热带常绿阔叶林气候、温带落叶阔叶林气候、温带针叶林气候等。森林气候的主要特点如下:①太阳辐射和日照时数比空旷地少。②林内温度变化和缓,年变化和日变化较小,白天林内温度较林外低,夜晚则林内温度较高。③森林内风速小。④森林内的相对湿度和绝对湿度比林外大,易产生雾、露、霜等水汽凝结物。⑤树冠截留部分降水,地下落叶残枝又能涵蓄降水,故森林地区径流小,而较多雨水渗入地下。提高森林覆盖率是改良气候的重要措施。 |
