在微风或无风条件下,采用沉积物捕获器和Gansith公式对异龙湖水体中颗粒物沉降和再悬浮进行了研究。结果表明:在微风或无风状态下,底泥再悬浮对水体悬浮物含量贡献较大;描述底泥再悬浮的动态过程需要的合适监测时间为48h。
Under windless and breezee conditions, deposition and re-suspension of suspended substance in the Yilong Lake were investigated by using sediment trapper and Gansith equation. The results indicated that un- der the windless or breezee conditions the re-suspension of bottom sludge made a dominant contribution to the concentration of suspended substances, and that 48 hours was appropriate monitoring time to describe the com- plex dynamic re-suspension of bottom sludge.
