山仔水库富营养化动态研究

以山仔水库库区水体为研究对象，通过测定水体透明度、叶绿素、总磷含量，应用卡尔森TSI营养指数法和层次分析法，并结合往年监测数据对山仔水库营养化程度进行分析，此外还运用Arc／Info的克里格插值法进行富营养化空间格局分析，最后提出防治对策。分析结果表明：近年来水库富营养化程度不断上升，随季节和降雨的变化出现较大的波动，在空间分布上也出现较大的变化。

Assessment of the Eutrophication in Shanzai Reservior

This paper studied the water of Shanzai Reservoir by gathering and analyzing water samples in the Shanzai Reservoir and then quantitatively measuring Secchidisk depth(SD),the concentration of CholrophyII-a(Chla) and total phosphorus(TP).It also used trophic state indexes(TSI) method and hierarchical analysis to treat the experimental result and compare the present data with the past data,and used Fractal dimension method to compare the eutrophication in different places in Shanzai Reservoir.Finally,many prevention measures were brought out.The results showed that the extent of eutrophication in Shanzai Reservoir was high in 1998,1999 and 2000,fell in 2001 and 2002,and has risen since 2003;the extent of eutrophication is low in the inlet but high in the center and the outlet.
