    <p><i>a</i>, <i>b</i> are coefficients of the Eq. (), <i>Q</i><sub>10</sub> is the temperature sensitivity of soil respiration (), <i>r</i><sup>2</sup> is the determinant coefficient. n is the number of samples data. Numbers in brackets represent the standard error of the mean. A one-way ANOVA was used to compare <i>a</i>, <i>b</i>, and <i>Q</i><sub>10</sub> values among different vegetation patches (n = 3). Different letters indicate significant difference (<i>P</i><0.05) among different vegetation patches.</p

    <p>(A), daily means of net radiation and soil temperature (Tsoil) at 10 cm depth; (B), daily means of soil water content (SWC) at 10 cm and 20 cm depth and precipitation; (C), averaged shoot and root biomass of <i>Phragmites australis</i> and <i>Suaeda salsa</i>; (D), daily means of soil respiration (SR). Error bars represent ± SE.</p

    <p>Shoot biomass (A), root biomass (B), litter biomass (C), SOC (D), total C (E), and total N (F) of three adjacent vegetation types (<i>Phragmites australis</i>, <i>Suaeda salsa</i> and bare soil sites). Bars represent standard errors of the means. One point represents the average soil respiration and average environmental factors of each patch during one month of measurement. Closed circles (•) represent <i>Phragmites australis</i> community, open circles (○) represent <i>Suaeda salsa</i> community, and closed triangles (▴) represent bare soil site.</p

    <p>(A), At the landscape and regional scale (from several kilometers to tens of kilometers), various vegetation types develop and wriggle upwards along with the river pathway from the sea to the land (Modified from Fang <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0091182#pone.0091182-Fang1" target="_blank">[33]</a>); (B), At the field scale (from several meters to tens of meters), the spatial distribution patterns of vegetation are mostly identified as patches of <i>Phragmites australis</i>, <i>Suaeda salsa</i> or bare soil in many sites.</p
