岩滩水库水质与浮游生物完整性灰色关联分析
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(CODMn)为影响3种养殖类型水域P—IBI指数值的主要理化因子。...

| Bibliography: | 44-1267/S 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, CODMn were the major factors influencing P-IBI value.
