0 cm Soil Temperature of Forest Gap in Pinus koraiensis-dominated Broadleaved Mixed Forest Based on Geostatistical Analysis
[Objective]To reveal temporal and spatial variation of forest gap 0 cm ground temperature in Pinus koraiensis-dominated broadleaved mixed forest in Xiao Xing'an Mountains.[Method]Taking forest gap of Pinus koraiensis-dominated broadleaved mixed forest in Xiao Xing'an Mountains as the research object,the growth season of the forest gaps of 0 cm ground temperature were continuously observed by the method of the grid.And spatial distribution pattern of gap 0 cm ground temperature was analyzed and revealed by method of basic statistics and geostatistics.[Result]The results showed that the heterogeneity of extreme 0 cm soil surface temperature exitd 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 maxmum 0 cm soil surface temperature was highest in June,then decreased in the sequence of July,August and September.The maxmum and minmum value of mean monthly surface temperature were not fixed at the same location.The 0 cm soil surface temperature was highest in the bare ground,medium in forest gap and lowest in understory in the same month.[Conclusion]The study can provide basic data and theoretical references for gap regeneration and sustainable management of Pinus koraiensis-dominated broadleaved mixed forest.
