From Chaotianmen to Zigui,the Shannon-Weaver diversity index of phytoplankton changes undeely.4 the impact of sediment deposition on zooplankton in the waters studiedAccording to the results of the experiment, we had learnt that the species composition of zooplankton sampled had the same tendence-the species was from less to more, and the biomass was also gradually increasing. Particularly Copepoda had increased significantly in the type and quantity. The main of zooplankton at each sampling situs were protozoa and rotifers.

A detector array target of laser distant-field detect system is designed, and two key factors are analyzed. To determine the size of the array target, the laser diffract effect and the influence of atmospheric turbulence are discussed, three factors that influence the resolution of the array target are analyzed. Three factors are the dimension of laser speckle resulted by atmospheric turbulence, space sampling frequency based on sampling theory and the loss of the frequency spectrum function of the array detector.
