摘要: 以小兴安岭原始红松阔叶混交林林隙为研究对象,采用网格法布点,通过对生长季内林隙各样点极端地面温度的连续观测,利用经典统计学和地统计学的方法分析并揭示了林隙极端地面温度的时空分布格局。研究结果表明:林隙极端地面温度不同空间样点之间存在异质性,而且异质性的强度、 尺度和空间结构组成随时间而改变,各月平均极端地面温度斑块形状复杂,最高地面温度大小顺序均为6月>7月>8月>9月,最低地面温度大小顺序为7月>8月>6月>9月,月平均地温的最大值和最小值分布位置不固定,同一月份地面最高温度的大小顺序是空旷地>林隙>郁闭林分,地面最低温度大小顺序是郁闭林分>林隙>空旷地。研究旨在为红松阔叶混交林的可持续经营提供基础数据和理论参考。

Abstract: Locations of measurement plot in forest gap of Pinus koraiensis dominated broadleaved mixed forests in Xiao Hinggan Mountains were established by the method of grids. Extreme soil surface temperature in the gap was continuously measured during the growing season. Its spatiotemporal distribution patterns were analyzed and revealed by fundamental statistics and geostatistical method. The results showed that: the heterogeneity of extreme soil surface temperature existed among different locations in the gap. The intensity and scale of spatial heterogeneity changed over time and the complex degree of patch shapes were also different. The maximum soil surface temperature was the highest in June, then decreased in the sequence of July, August and September. The minimum soil surface temperature was the highest in July, then decreased in the sequence of August, June and September. The maximum and minimum values of mean monthly surface temperature were not fixed at the same location. The maximum soil surface temperature was the highest in the bare ground, medium in forest gap and the lowest in understory in the same month, the latter was the highest in understory, medium in forest gap and lowest in the bare ground. The aim of our study was to provide basic data and theoretical references for gap regeneration and sustainable management of Pinus koraiensis dominated broadleaved mixed forest.
