  • 地理位置

    鼎湖山南亚热带常绿阔叶林通量观测站设置在CERN鼎湖山森林生态系统定位站内。位于广东省肇庆市鼎湖山保护区内,北纬23°09′~23°11′,东经112°30′~112°33′。实验站地处低山丘陵,海拔在14~1000 m之间。

  • 气象特征

    该站点属南亚热带季风湿润气候,年均气温20.9 ℃,7月平均气温为28.1 ℃,1月为12.0 ℃,极端最低气温零下0.2 ℃,偶有短暂霜冻;年均降水量1956 mm;年均相对湿度82%。干湿季节明显,4~9月份为雨季,10月至来年3月为旱季。

  • 植被类型

    鼎湖山的植被为南亚热带典型的常绿阔叶林,是北回归线附近保存完好的南亚热带地带性植被。植物种类繁多,亚热带植物类型为优势种,热带植物类型也有较多分布。植被类型多样,可分为季风常绿阔叶林、山地常绿阔叶林、针叶阔叶混交林、针叶林、沟谷雨林、常绿灌丛和山地灌木草丛等不同类型。季风常绿阔叶林分布在保护区的核心区,面积125 hm2,保存较完好, 已有400多年的保护历史, 是南亚热带代表性的森林类型。季风常绿阔叶林为锥栗(Castanopis chinensis)、荷木(Schim asuperba)、厚壳桂(Cryptocarya chnensis) 群落。林冠重叠、稠密, 种类丰富, 结构复杂, 垂直结构可分为6层, 即乔木3个亚层, 幼树灌木层、草本苗木层, 层间植物层。季风常绿阔叶林样地的母岩为沙页岩。土壤为赤红壤, 土层深60-90 cm,表层有机制含量2.94%-4.27%。

  • 观测系统

    观测塔高36 m,其上安装了7层常规气象系统,分别位于4 m、9 m、15m、21 m、27 m、31 m和36 m处;两套开路式涡度相关通量观测系统,分别位于2 m和27 m处。同时该站还安装了测量土壤CO2、CH4和N2O排放量的箱式法观测系统。
