宽叶香蒲人工湿地水体生物生态学调查

An ecological investigation of water body organisms in Typha latifolia wetland

对以宽叶香蒲(Typha latifolia)为优势种的人工湿地系统水体中菌类、藻类和原生动物进行生态学调查,评估湿地对采矿废水治理的长期效能,探索系统中各组分的恢复与采矿废水处理长期效能与稳定性的关系.研究结果表明,宽叶香蒲湿地系统中有40种藻类植物隶属于5门31属,80种原生动物隶属于2门6纲21目56属,其中鞭毛虫42种,肉足虫6种,纤毛虫32种,菌类主要为假单胞菌属及产碱菌属.随着采样点至排污口距离的增加,水体中菌类、藻类及原生动物的种类和数量呈上升趋势.

This paper describes the use of a man-made wetland with Typha latifolia as the dominant species, to treat the wastewater from a Pb/Zn mine at Shaoguan, Guangdong Province, in China since 1985. Algae, bacteria, protozoan have been investigated for evaluating the long-term efficiency of the man-made wetland in metals removal and exploring the ecological succession within the system and the function of each ecological compartment. There are totally 40 algae species in 31 genera recorded. And 80 protozoan species belong to 2 Phylum, 6 Classes, 21 Orders, 56 Genera. Among them, there are 42 Mastigophora, 6 Sarcodina and 32 Ciliophora. The bacteria Genera mainy belong to Pseudomonas fluorescens and Alcaligenes xylosoxidans on the wetland. With the distance of the sampling site away from discharge increasing, the species and number of algae, bacteria, protozoan communities have increased.
