A highly diversified macrofossil assemblage was discovered from the Jiucheng Member of the uppermost Ediacaran of Jinning and Jiangchuan areas in eastern Yunnan. In addition to abundant Vendotaenia and Tyrasotaenia, large multicellular benthos such as Tawuia-like and Longfengshaniaceae fossils with diverse holdfast structures, have a distinct dominance, while there are still some other macrofossils with peculiar configurations as well as indistinct relatives. There is an obvious distinction between this assemblage and the macrofossil assemblages from the Doushantuo Formation and the Shibantan Member of the Dengying Formation in South China.

Between July and September 2002, we made a survey on species diversity in 7 main mangrove areas of the Leizhou Peninsula. Totally 188 kinds of benthos were digged out, among them 110 kinds belong to Mollusk, 48 kinds to Arthropods, 18 kinds to Fish, 3 kinds to Sipunculan, 8 kinds to Polychaete, and 1 kind to Brachiopoda.

2002年7~9月，对雷州半岛7个主要红树林区生物多样性进行了调查，采集到底栖动物共188种，其中软体动物有110种，节肢动物门48种，鱼类18种，星虫门3种，多毛类8种，腕足动物门1种。

It is shown from the assessment results that (1) both the TN and TP fluxes discharged from the Changjiang River to the Changjiang River estuary sea area increased continuedly, the DIN concentration in the sea areas increased continuedly, and the Si concentration decreased continuedly, which resulted in the significant changes in N/P/Si ratios;(2) the chlorophyll a concentration in the sea areas increased continuedly, and the significant changes in community structure of phytoplankton occurred;(3) the species and biomass of benthos declined greatly, and the bottom oxygen-poor water area increased significantly;(4) the range and occurrence frequency of red tide events in the sea areas increased greatly, and the algal toxic infection events of mussel were frequently found in the sea areas.

结果表明，长江向长江口海域输送总氮和总磷通量持续增大，长江口及其邻近海域无机氮浓度持续增高而硅浓度持续下降，并由此导致N/P/Si与比值的显著变化；该海域叶绿素a浓度持续增大，浮游植物群落结构也发生了显著变化；该海域底栖生物种类和生物量都大大减少，底层水低氧区面积也显著扩大；该海域赤潮事件无论是规模还是频率都大大增加，藻类毒素DSP/PSP贻贝传染事件也时有发生。

Benthos feeders were bottom-dwelling or demersal species.

With Protosalanx hyalocranius,Coilia nasus and Salangichthys tangkahkeii as test objects,a food web model of main economic fishes in Taihu Lake was established,with which,the distribution characteristics of DDT in the benthos,zooplankton and fishes of the food web were studied by Monte Carlo simulation method,and one-hit model was used to approach the ecological risk of the DDT distribution.

选取滴滴涕(dichloro-diphenyl-trichloro-ethane，DDT)作为太湖持久性有机氯污染的代表性污染物，以大银鱼、陈氏短吻银鱼和刀鲚为研究对象，建立太湖主要经济鱼类食物网模型，并结合DDT的生物化学特性以及蒙特卡罗不确定性分析方法，应用食物网模型研究DDT在食物网主要经济鱼类中的迁移分布特性，分析由此导致的生态风险。

When we used those two multivariate statistic analytical techniques to study the spatio-temporal variation laws of benthic community structure at Shenzhen Bay, the results indicated that: 1 There was not obverse difference in intertidal benthic community structure between Futian, Shenzhen and MaPi, HongKong in Shenzhen Bay in Spring, 2000. However, there was continual gradient change in community structure from outer bay to inner bay. 2 There was obvious deference with the respect of benthic community structure between station C and stations Al, A2, A3 in transect A and station B in transect CBA in Shenzhen Bay. There being no benthos at station C in Summary, 2000, it indicated that station C had been polluted very heavily. 3 Deferent seasons and deferent tide sites are the most two important factors which play influence on benthic community structure at stations Al, A2, A3 and B3 in Shenzhen Bay.

用这两种多变量方法研究深圳湾底栖动物群落结构时空差异，结果表明(1)2000年春季深圳湾底栖动物群落结构组成在深圳福田一侧与香港米埔一侧并没有明显的差异，而是沿湾外向湾内呈现连续的梯度变化；(2)在深圳福田一侧的C断面的底栖动物群落结构与A、B断面有明显的差别，2000年夏季在C断面没有采到任何底栖动物，表明C断面已经遭受了严重的污染；(3)季节和潮区是影响深圳湾A1、A2、A3、B3站位底栖动物群落结构组成时空差异的两个最重要的因素。
