| 摘 要： | 秋茄红树林不同季节落叶分解失重速率研究表明:落叶的干重损失速率是夏>秋>春>冬。就失重过程而言,最高的失重速率和季节间最明显的分解速率差异都出现于分解初期,淋溶作用很可能是引起这一分解特征的重要原因。落叶在林地滩面外滩(中潮带).中滩和内滩(高潮蒂)分解28d时的失重率分别为53.4%、44.8%和48.9%,即外滩>内滩>中滩。中潮带比高潮带具有较高的潮浸频度和滩面潮湿度,使得落叶在中潮带的分解快于高潮带。

| Abstract: | The seasonal in situ decomposition experiments of Kandelia candel fallen leaves were performed in the period from Winter 1986 to Autumn 1989, and the results showed that the disappearance of dry weight was in the order of Summer>Autumn>Spring>Winter. As regards of the process of weight-loss, both highest loss rates and the most obvious decomposition differences between seasons occurred in the early stage of decomposition, which was much possibly ascribed to leaching. Relatively high inundation frequency and moisture of the midtide were responsible for the fact that the rates of weight-loss were higher in midtide than in higtide zones. |
