| 摘 要： | 中国多数红树林陆地边缘存在着大量的养虾池塘。这些养虾池塘可通过：（1）换塘外排废水,（2）清塘直排污泥影响周围的红树林。本研究共包含两个实验,来探讨这两种类型的排污对秋茄幼苗生长的影响。实验一模拟虾池常规换塘情况,研究换塘废水对秋茄幼苗生长的影响。实验二设置四种虾池清塘污泥沉积厚度（0 cm,2 cm,4 cm,8 cm）,研究虾池清塘污泥的累积效应对秋茄幼苗生长的影响。结果如下：在5,15和25三种盐度下,虾池换塘废水未对秋茄生长指标造成显著影响;而清塘污泥对秋茄生长的影响与其沉积厚度有关,大多数生长参数在污泥沉积厚度为4 cm时呈现最大值。秋茄幼苗在适量的沉积厚度下加速了生长,且本实验秋茄幼苗对虾池清塘污泥的耐受性为沉积厚度8 cm。

| Abstract: | Extensive shrimp ponds are located next to the landward edges of most of mangrove forests in China. A shrimp pond may influence mangroves by (1) routine effluent between pond and tide, and (2) dredging effluent from pond-dredging at least once a year. Our study consisted of two experiments to study the effects of these two effluents on the seedling growth of Kandelia obovata. One experiment simulated the effects of routine effluents. The other simulated four sedimentation thicknesses (0 cm, 2 cm, 4 cm, 8 cm) over mangrove soils by dredging effluent from pond-dredging, and revealed the cumulative effects of dredging effluents on K. obovata. At each of the three fixed salinities, i.e., 5, 15 and 25, routine effluent did not result in significant differences in each of the measured growth parameters of K. obovata seedlings. However, effects of dredging effluent on seedling growth of K. obovata were related with sedimentation thickness. Most growth parameters showed maximum values at sedimentation thickness 4 cm. The data indicated that K. obovata accelerated its growth under moderate sedimentation thicknesses and it was tolerant and adaptable to shrimp pond-cleaning effluent sediments up to about 8 cm in our experiment. |
