Abstract

Abstract

As one of the most important interfaces of material cycle, energy and species flows between coastal wetlands and adjacent waters, mangrove forest edge is of great scientific importance in understanding the interaction between different ecosystems, biogeomorphogical processes and dynamics of soil organic carbon pool in coastal areas. In order to determine the edge effects and their impact on the soil organic carbon pool, 4 coastal landform types of mangrove distribution area in the east coast of Leizhou Peninsula were selected for investigation. Three subzones of barren flat, forest edge and forest interior were then further indentified in each landform type. The forest structure in the edge and interior, as well as the edaphic physiochemical features for all three subzones were investigated in low tide in August, 2011. Different patterns of vegetation and soil physiochemical indicators were compared among the 4 mangrove landforms. Generally, the edge effect on vegetation was characterized by relatively lower canopy height, leaf area index and species richness in the forest edge than the interior (except the estuarial mangroves). Vegetation coverage decreased with landforms in the forest edge as estuary(QL)> inner bay(TF)> island(TC)> wave hit bench(TJ), coinciding with the degree of wave and storm hit to the areas. The edge effect on soil physicochemical properties in most cases (except TF, the inner bay) showed soil pH, mean grain size in the forest edge were less than that in the barren flat, while redox potential, salinity showed higher on the contrary. But these soil properties in the forest interiors were largely variable among different landforms, since they could be sensitive to the effects of vegetation succession behind the forest edge and microtopography as well. However the SOC (surface soil organic carbon content) and soil organic carbon density increased significantly from the barren flat to the interior in each type of the landforms. Principal component analysis and correlation analysis showed the first principal component, reflecting the joint effect of vegetation cover, leaf area index and soil pH, was negatively correlated with the surface organic carbon density. In other word, despite the variation and strong impact of hydrogeomorphology, organic carbon enrichment in mangrove soil was resulted from the increase of primary production and development of acid edaphic settings.
