摘要/Abstract

摘要： 研究了广东省19座主要水库2000年丰水期和枯水期浮游植物状况,并根据浮游植物群落结构和多样性指数对水库进行营养状况评价。结果表明,东江流域的新丰江和白盘珠水库水质良好,属于贫营养型水库;大部分水库为中营养型,而鹤地、契爷石和石岩这3座位于沿海经济发达地区水库属于富营养型。流域上游水库水质明显优于下游水库,山区水库水质优于沿海水库,东江流域水库水质普遍较好,北江流域次之,而粤西沿海和珠江三角洲地区各水库均受到不同程度的污染.

Abstract: A phytoplankton survey was conducted in flood and dry seasons in 2000 in 19 reservoirs of Guangdong Province,China.Based on phytoplankton community structure and three diversity indices (Shannon-Weaver diversity index,Pielou evenness index and McNaughton abundance index),this paper assessed the trophic stae of reservors.The results showed that Xinfengjiang and Baipanzhu reservois were oligotrophic,and most of the reservoirs were meso-trophic,while Hedi,Qiyeshi and Shiyan reservoirs,which located in highly developing area,were densely polluted and belonged to eutrophic waters.Results showed that trophic level in reservoirs located in upper stream and mountainous district was significantly lower than that in down stream area and coastal region.Overall,the water quality of reservoirs along Dongjiang River was better than that of other watersheds especially those in the west coastal area and Pearl River Delta.

Key words: Scale, Spatial pattern, Semivariogram
