周年性采样, 测定岩滩水库主库区 3 种养殖类型水域主要水质因子, 构建浮游生物完整性体系
(P-IBI) , 用灰色关联分析法研究 P-IBI 指数值与水质因子的灰色关联度, 综合评价监测水域的生态系统健
康状况。 结果表明, 岩滩水库围栏养殖水域(C 水域)生态系统健康状况总体优于网箱养殖次密集水域(B 水
域)和网箱养殖密集水域(A 水域) ; pH 值、 水温(WT)和化学耗氧量(COD Mn )为影响 3 种养殖类型水域
P-IBI 指数值的主要理化因子。 |
英文摘要: |
In order to assess the ecosystem condition of Yantan reservoir, 3 points of different aquaculture types
were set in Yantan reservoir to examine the main physical and chemical factors affecting water quality, sampling once a
year. So as to construct the evaluation system of Plankton-index of biotic integrity(P-IBI) , the grey relation analysis
method was use to analyze the relationaship between P-IBI and water quality in Yantan reservoir. The results showed
that, the ecosystem condition of pen-closing culturing pattern(point C)was better than that of cage culturing inferior
intensive pattern(point B)and cage culture intensive(point A) pattern in Yantan reservoir. pH, water temperature,
COD Mn were the major factors influencing P-IBI value. |
