中文摘要：

基于水藻的遥感图象，现在的工作在乔胡·莱克，分析海藻的花蕾的水平分发特征中国，它也在不同的风方向下面揭示海藻的花蕾的频率。进一步，一个未组织格子的、三维的有限卷的沿海的海洋模型(FVCOM ) 被使用调查导致风的水流和运输过程解释海藻的花蕾在检测地方发生的原因。我们首先从覆盖卫星图象推出生物资源的主要分发，并且解释由分析污染，并且在占优势下面模仿流动域和交通过程的形成机制在乔胡·莱克上采购风。然后，我们在相应的天考虑风的调整行动并且开发一条二时间的规模途径描述水藻的整个形成过程在乔胡·莱克的水平分发。也就是说在更长的时间可伸缩，即在花蕾季节期间，占优势风由导致典型流动地决定生物资源的主要分发；在更短的时间规模上，即在花蕾发生的日子，风力量调整生物资源的主要分发形成海藻的花蕾的最后的分发。

英文摘要：

Based on the remote sensing images of algae, the present work analyzes the horizontal distribution characteristics of algal blooms in Chaohu Lake, China, which also reveals the frequency of algal blooms under different wind directions. Further, an unstructured-grid, three-dimensional finite-volume coastal ocean model （FVCOM） is applied to investigate the wind-induced currents and the transport pro- cess to explain the reason why algal blooms occur at the detected places. We first deduce the primary distribution of biomass from overlaid satellite images, and explain the formation mechanism by analyzing the pollution sources, and simulating the flow field and transportation process under prevailing wind over Chaohu Lake. And then, we consider the adjustment action of the wind on the corresponding day and develop a two-time scale approach to describe the whole formation process of algae horizontal distribution in Chaohu Lake. That is, on the longer time scale, i.e., during bloom season, prevailing wind determines the primary distribution of biomass by inducing the characteristic flow field; on the shorter time scale, i.e., on the day when bloom occurs, the wind force adjusts the primary distribution of biomass to form the final distribution of algal bloom.
