| 中文摘要: |
| 采用灰色系统关联度分析方法,以空间理论数学为基础,依规范性、偶对称性、整体性和接近性原则,计算并分析了在人工控制条件下澧县王家厂水库13个生态因子(透明度、水深、水温、溶解氧、酸碱度、电导率、氨氮、硝酸盐氮、总磷、总氮、氮磷比、浮游动物和浮游植物)的关联度,南河关联序结果为:氮磷比>总氮>硝酸氮>氨氮>浮游植物>浮游动物>溶解氧>酸碱度>总磷>水温>电导率>透明度>水深;北河:氮磷比>总氮>总磷>硝酸氮>浮游动物>水温>水深>酸碱度>溶氧>透明度>浮游植物>电导率>氨氮。分析表明,氮磷比、总氮和总磷是水库水体的优势影响因子。在研究过程中发现,除个别样点超出Ⅲ类水标准外,其余均在Ⅲ类范围内;说明王家厂水库在放养鱼类的情况下,通过合理的人工能量投入,可以达到既增加水体生物的多样性,又提高水体生产力,实现水生态保护的目的。 |

| Based on the mathematics of space theory，and according to the normalization，symplectic symmetry，integrity and accessibility，we calculated and analyzed the relevancy of 13 ecological factors of Wangjiachang Reservior through the grey relational analysis under the condition of manual control，including water transparency，water depth(WD)，water temperature(WT)，dissolved oxygen(DO)，pH，conductivity，ammonia nitrogen(NH4+-N)，nitrate nitrogen(N03--N)，total phosphorus(TP)，total nitrogen ( TN)，ratio of TN to TP(TN/TP)，zooplankton and phytoplankton. The results showed that for the South River, the relational order from high to low was that TN/TP，TN，N03--N , NH4+-N ,zooplankton，phytoplankton，DO，pH，TP, WT，conductivity，transparency，WD; meanwhile，for the North River, the order was that TN/TP, TN，TP，N03--N，zooplankton，WT,WD，pH，DO，transparency，phytoplankton，conductivity，NH4+-N. In this study，we could conclude that the ratio of TN to TP，TN and TP were dominant factors of reservoir. Moreover, the research found most of indexes values were within the standards for Grads III water quality，except that just a few indexes values were above the standards for Grads III water quality. Description of Wangjiachang Reservoir in artificial stocking fish case，through reasonable artificial energy inputs，can not only increase the biological diversity，but also improve water productivity and water ecological protection. |
