The result showed that:(1) There were a higher density of Ostreidae and Balanidae and a lower biodiversity in the cay sampling section of Daxie Island.(2) No significant difference was found in the macrozoobenthos community among the tide plat sampling section in Daxie Island.(3) There was a lower macrozoobenthos species number, biodiversity, and a higher density of Sternaspis scutata and Capitella capitata than those in the sea area beside Daxie Island. Moreover, a significant difference was found in the macrozoobenthos community between the sea area of Daxie Island and the adjacent islands.

结果发现：(1)大榭岛岩相潮间带断面牡蛎科和藤壶科等科的物种栖息密度较高，生物多样性较低；(2)泥沙相潮间带底栖动物状况与其他海岛差别不显著；(3)大榭岛近岸海域底栖动物种数少于其他海岛近岸海域，且前者不倒翁虫和小头虫等多毛类物种栖息密度较高，生物多样性较低，群落结构与其他区域相差较大；(4)环境质量的生物评价结果显示，大榭岛近岸海域扰动程度高于其他海岛近岸海域。

In multivariate analysis, we found temperature, sampling year, sampling month and O3 were important environmental factors associated with culturable fungi and fungal spores.

温度、采样年份、采样月份及O3是可培养性真菌及真菌孢子的重要影响因素，但是对於可培养性细菌则没有发现任何显著的相关环境因子。

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.
