It was revealed that the total cell density increased from early March to May, with a variation of 3 order of magnitudes in cell richness; Amphidinium britannicum and Adenoides eludens were two dominant species in the spring, however Gyrodinium viridescence and Peridinium quinquecorne might be abundant in the early summer; the cell density of dominant species inclined from the high-tide zone to middle- and low-tide zone. Finally, the importance of sonification treatment in precise cell enumeration of nature samples was discussed.
发现初春甲藻数量少,而春末夏初数量显著增多,由春初的0~20个/1 000 g湿砂增加到春末夏初的几千个/10 g湿砂,相差3个数量级以上;Amphidinium britanicum和Adenoides eludens为春季优势种;Gyrodinium viridescense和Peridinium quinquecorne在5月份数量明显增多,与温度升高以及底栖藻类各类群总量增加有密切关系;底栖甲藻的总细胞密度和主要优势种的细胞密度呈现由高潮带向中、低潮带增加的趋势。

The results of toxicity experiments showed that R32 would not cause acute, chronic, cumulative and genetical toxicity effect on algae, Allium cepa, Zebra, fish and mice before it absorbed Cr. The recovery and sterilization measurement in routine water treatment could reduce most of the R32 in effluent. This may ensure that the effluent would not cause any ill effect on all kinds of biology in the environment after it was discharged into the river.
毒性实验结果表明:在吸附Cr~(6+)以前R_(32)对微生物无致突变性,对藻类、洋葱、斑马鱼和小鼠无急性毒性、慢性毒性和蓄积毒性;吸附Cr~(6+)后,常规水处理中的各种回收和杀菌措施可以降低出水中R_(32)的量,使出水排入江河后不会对环境中的各种生物产生不良的影响。

Enteromorpha was used as food and pharmaceutical product since ancient times.some pharmacodynamic action components are contained in Enteromorpha.for example,it has amount of anti- anabrosis substance which effected on anabrotic patient and duodenal ones efficiently.But the studies about polysaccharide of Enteromorpha are less. Enteromorpha has many good qualities ,distinct more widely,lower price et.al.which are excellent resource to develop marine drugs.In this study, we determined the regulating blood sugar and blood lipid activity of alkali-extracted polysaccharide from Enteromorpha.
浒苔自古即为食用和药用藻类,它有很多药效成份,如浒苔中具有大量的抗溃疡物质,对胃溃疡患者和十二指肠患者有效,但有关浒苔多糖的研究国内外文献报道较少,浒苔分布广泛具有取材方便,价格低廉的优点,是开发海洋药物的极好资源,本文选用浒苔作为研究材料,用碱提取浒苔细胞壁多糖并对其有无降血糖、血脂的生物活性进行研究。

The single-celled phytoplankton included 116 inshore wide distribution species, 31 inshore warm-water species and 26 inshore temperate species, and the vascular plants were of 6 ecological groups, i.e., halophtes (24 species), hydrophtes (22 species), amphiphytes (35 species ), mesopllytes (103 species), zerophytes (6 species), and psammons (4 species). Halophtes, hydrophtes, and amphiphytes were the edificators and dominants, reflecting the azonal feature of the wetland vegetations. The vascular plants were divided into 5 life-forms, including 20 phaenerophytes, 4 chamaephytes, 54 hemicryptophytes, 48 geophytes and 68 therophytes, among which, hemicryptophytes and geophytes accounted for 52.58%, reflecting the relatively important function of cold and wet climate and local water-accumulated bottomland environment on the vascular flora formation.
