摘要
从理论上分析了风加快北大港水库水体水质咸化速度的原因,一是由于风对水体的扰动作用,加快了盐份从底部土壤向整个水体的扩散速度,二是风可加快水体的蒸发速度,加速了水体的蒸发浓缩作用,并通过有风、无风的对比实验定性地证明了此结论。
The mechanism that wind can accelerate water salinization in Beidagang reservior is analyzed theoretically. On one hand, wind can agitate water body and accelerate the diffusion rate of salt from saline soil to water. On the other hand, wind can enhance the evaporation and accelerate water salinization. This conclusion is testified by two contrastive experiment with wind or without wind.
