In order to let Apparent Hurst exponent be greater than 1, an accelerated fractional Brownian motion is introduced based on the fractional Brownian motion. A new particle tracking technique is established to model the non-Fickian dispersion in coastal waters.

因此本研究在分数型布朗运动的基础上，引进加速分数型布朗运动来模拟non-Fickian扩散，使表面Hurst指数可以大于1，从而建立了一种新型的粒子追踪技术，由此来模拟沿海水域中的non-Fickian传播。

The conclusion is that the building of hydrostation will change not only the amount and or of river ecosystem services ,but also the accepter of these services.And further more,enormous benefits gained from hydroelectricity is at the price of the decrease even the vanishment of some ecosystem sersvices and the resulted complex social and economic problems.

研究认为，水电站建设使河流生态系统提供的各项服务的量、形式以及服务对象等都发生了巨大的变化和转移，而且水电巨大经济效益的产生是以部分"廉价"享用的生态系统服务的降低或丧失以及由此引发的错综复杂的社会、经济问题为代价的。
