| 摘 要： | 文章探究广西水库的沉积物中碳的积累及其与开发种植历史、降雨状态的关系。水库沉积物是由沉积在主要入口附近的粗糙沉积物与深水环境中积累的沉积物组成。对沉积物进行总碳和有机碳分析发现,浅水区的总碳变化比深水区明显,说明沉积物的积累与降雨呈线性关系。沉积物的清理被回用于周边的农田土地及新耕地的开垦,但沉积物的利用对农田土地存在的利弊影响有待进一步研究。

| Abstract: | The paper elaborates the amount of catchment-derived carbon accumulated in sediments of a reservoir in Guangxi and its relations between the history of cultivation and rainfall regime in the watershed.The yearly supply of catchment-derived material is composed of coarse sediment deposits near the main inlets and of laminated sediment accumulations in deep-water environments.The analysis of the total carbon sediments and organic carbon finds that total carbon sediments in shallow water is more obvious than i... |
