项目摘要
To quantify the material budget focusing on fine scale sand in coastal water body, we developed monitoring systems and conducted the field observations. From comparison of monitoring results of water qualities in urban area, SS increased about 10 times immediately after rain. On the other hand, turbidity in mangrove estuaries didn't change soon and the rate of increase was remarkably smaller than in urban river. In addition, TN (Total Nitrogen) and TP (Total Phosphorus) also had same tendencies. It showed that mangrove natural rivers moderate excess outflow of solids and nutrients to coastal area. Our observing system, successfully captured periods of timing, rainfall events, and subsequent changes in SS and nutrients in coastal region.
为了量化沿海水体中细粒沙的材料预算,我们开发了监测系统并进行了现场观测。从城区水质监测结果对比来看,雨后SS增加了10倍左右。另一方面,红树林河口的浑浊度变化不大,增幅明显小于城市河流。此外,TN(总氮)和TP(总磷)也有相同的趋势。结果表明,红树林天然河流调节了固体和营养物质向沿海地区的过量流出。我们的观测系统成功捕获了沿海地区的时间周期、降雨事件以及随后的SS和营养盐变化。
