以林窗北侧林缘为中心， 研究了西双版纳地区橡胶林林窗及周边ＮＳ样带上气温水平梯度分布。结果表明： 干季落叶期林窗及周边主要热力作用面在地面， 但林缘的增温效应也相当明显， 各热力作用面热量收支是林窗小气候形成的物理基础； 林缘冠层结构、林缘乔木高度（ Ｈ） 与林窗直径（ Ｄ） 之比（ Ｈ／ Ｄ） 、太阳高度角、方位角、天气状况将影响林窗辐射平衡各分量的变化， 林缘乔木群落结构的不同是造成林窗小气候差异最直接的原因； 版纳多雾的环境条件使得测区林窗热力状况更富特点， 主要表现为测区上午温度时间及水平梯度变化均不明显， 水平变化曲线近乎水平， 即使正午时分也是很小； 林内、林缘、林窗中央区气温日变化曲线均为单峰型， 但峰值时间较旷地表现为不同程度的滞后， 表现在振幅大小上也不相同； ８ 时北侧林墙为冷源， 林缘附近温度较低， １３ 时为热源， 林缘附近温度较高； 平均最高温度、气温日较差以北侧林缘为最大， 其次南侧林缘， 再其次林窗中央， 林内最小；上午均温相差不明显， 下午及昼间均温以林窗中央为最大， 其次南北侧林缘， 林内最小； 北侧林缘增温效应并不局限于林缘本身， 同时牵动周边温度的上升， 但这种增温效应随进入林内距离的加深呈指数递减之势?
Taking the forest margin on the northern side of the forest gap as the center, the temperature gradient distribution on the N / S zone of the rubber forest gap and around the Xishuangbanna was studied. The results showed that the main thermal effect surface of the forest window and the surrounding forest in the dry season was on the ground, but the warming effect of the forest edge was also quite obvious. The heat budget of each active surface was the physical basis of microclimate in the forest gap. (H / D), solar elevation angle, azimuth angle and weather condition of the forest edge will affect the variation of each component of the radiation balance in the gap and the difference of arbor community structure Which is the most direct reason for the differences in microclimates. The environmental conditions of Banna Mist makes the thermal status of the gaps in the survey area more rich, mainly due to the obvious changes in temperature, time and horizontal gradients in the morning of the survey. The horizontal variation curve is almost horizontal, Even at midday, the daily diurnal variation curves of temperature in the forest, forest margin and forest gap were unimodal, but the peak time lags behind with different degrees of hysteresis, showing different amplitudes. At 8 o’clock The north wall is cold source, the temperature near the edge of the forest is low, and the temperature is around 13 o’clock. The temperature near the edge of the forest is higher. The average maximum temperature, The day on the north edge of the forest margin is the largest, followed by the south edge of the forest, followed by the middle of the forest window, the smallest forest; morning temperature difference was not obvious, afternoon and daytime temperature to the largest window center, followed by the north and south side of the forest The edge of the forest is the smallest. The warming effect of the forest edge on the north side is not limited to the forest edge itself, but also affects the increase of the surrounding temperature. However, this warming effect decreases exponentially with the distance into the forest.
