Spatiotemporal Heterogeneity in SWC in a Pinus koraiensis-Dominated Broadleaved Mixed Forest Gap in Xiao Xinganling’ Mountains, China

Abstract:

Spatiotemporal heterogeneity in SWC within 0-20 cm (upper layer) and 20-40 cm (lower layer) in a Pinus koraiensis-dominated broadleaved mixed forest gap in Xiao Xing’an Mountains of NE China was analyzed by using classical statistics and geographical statistics. The results indicated that the variation regularity in SWC within 0-20 cm was different from that within 20-40 cm during the growing season, the difference in SWC between the two layers reached significant level at P<0.01; the variability degree in SWC within every layer fell into medium variation. Spatiotemporal heterogeneity in SWC occurred with different degree during the study period. Autocorrelative spatial heterogeneity in SWC constituted the main part of total SWC heterogeneity. For SWC spatial distribution within different layer, the patches at medium and lower ranks dominated in forest gap, the patches at higher rank only distributed within 0-20 cm.
