英文摘要 | Studying the relationship between climate factors and soil organic carbon (soc) is vitally important. however, how soc responses to climate (temperature and precipitation) at cohesive extents is poorly studied. two transects of approximately the same length (transect p and transect t) were selected to examine the variation of soc content in relation to mean annual temperature (mat) and mean annual precipitation (map). the coefficients of partial correlation between soc density and mat (rt) and map (rp) were determined to quantify the relationships between soc density and the two climate factors. the results indicated that for transect t, rt was statistically significant once the extent level was greater than or equal to two fundamental extent units, while for transect p, rp showed statistical significance only at extent levels which were greater than two fundamental extent units. at the same extent levels but in different transects, rts exhibited no zonal difference, but rps did once the extent level was greater than two fundamental extent units. therefore, to study the relationship between soc density and different climate factors, different minimum extent levels should be examined. the results of this paper could deepen the understanding of the impacts that soc pool has on terrestrial ecosystem and global carbon cycling. |
