英文摘要	Soil organic carbon is a major carbon pool in tidal wetland ecosystems. By dividing the level of the tidal creek and calculating its morphological characteristic index, the spatial distribution characteristics of the typical tidal creek system were analyzed, taking a typical natural tidal channel as the research object. The spatial distribution characteristics of soil organic carbon were analyzed by geostatistical methods. In addition, the effects of morphological characteristics of the tidal creek on the spatial distribution of soil organic carbon were explored. The results showed that there was obvious spatial heterogeneity in the morphological characteristics of the tidal creek. In the middle tidal flats, the connectivity of the tidal creek network was higher, and the density, curvature and bifurcation ratio were also higher than that in other tidal zones. The tidal creek length gradually increased with the increase of tidal creek development grade, while the tidal creek curvature gradually decreased with the increase of tidal creek development grade. The spatial interpolation results showed that the lowest soil organic carbon in 0 to 10 cm soil layer occurred in the middle tidal flats where tidal creeks were more developed, and within the 10~ 20 cm soil layer, soil organic carbon showed a gradually increasing trend from sea to land, and showed a strip-shaped spatial distribution choracteristic. In the low tidal flats, the mean value of soil organic carbon in a third-order creek was significantly greater than that in a first-order creek. In the middle tidal flats, the mean value of soil organic carbon in a second-order creek was significantly greater than that in a third-order and a first-order creek. The soil organic carbon of the high tide flats was not significantly correlated with the tide creek development level. Within the 0 to 10 cm soil layer, the soil organic carbon gradually increased with increasing distance to the tidal creek in low and middle tidal flats. Within the 10 to 20 cm soil layer, the soil organic carbon gradually decreased with increasing distance to tidal creek in the middle tidal flats. However, there was no correlation between the soil organic carbon and the distance to the tidal creek in high tidal flats. The spatial heterogeneity in the morphological characteristics of the tidal creek was one of the important factors of spatial differences in soil organic carbon content in the tidal wetland. Therefore, morphology changes in tidal creeks should be considered in order to accurately estimate the soil carbon pools in tidal wetlands.
