| 灰色系统关联度分析方法是一种研究少数据、贫信息不确定问题的新方法，其量化结果与定性分析一致，具有广泛的实用性。以空间理论数学为基础, 按规范性、偶对称性、整体性和接近性四条原则，计算了人工控制条件下津市西湖12个生态因子（透明度、水深、水温、溶解氧、酸碱度、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，关联序结果为毛里湖：氮磷比>氨氮>硝酸氮>总氮>总磷>透明度>水深>酸碱度>浮游植物>水温>浮游动物>溶氧；西湖：氨氮>氮磷比>总氮>总磷>硝酸氮>水深>酸碱度>浮游动物>浮游植物>水温>溶氧>透明度；结果表明氮磷比、氨氮、总氮、总磷和硝酸氮是水体的优势影响因子，溶氧、浮游动物、浮游植物和水温则是相对次要的影响因子，大水面施肥使西湖水体的氮磷比调控到了较好的状态（毛里湖15.35±5.71；西湖9.92±1.97），符合浮游植物生长繁殖的营养需要。 |

| Grey relational degree analysis，a new problem analyses strategy，has its peculiar advantage， such as：low sample amount and distribution rule require，simple and efficient．Its results consist with qualitative analysis and it has been widely applied．In this study，the grey incidence and relation degree of 12 ecology factor（water transparency（SD）、water depth（WD）、water temperature（WT）、dissolved oxygen（DO）、pH、NH4-N、NO3-N、total phosphorus（TP）、total nitrogen（TN）、TN／TP、zooplankton and phytoplankton）in Xihu Lake，which were under the conditions of manual control and was a medium sized and shallow lake in jingshi city，Hunan province，were evaluated by use of the theory，by means of mathematical basis of space theory and the four principles：normalization，even symmetry，globalist and proximity，a row order of those effects were provided，The resulting indicated that TN/TP、NH4-N、TN、TP and NO3-N were the “advantage factors” that exhibited the greatest effects on the water environment，while parameters，such as DO、zooplankton、phytoplankton and water temperature，had less influence than other factors，the relation order in Maolihu Lake and Xihu Lake，the in descending order of importance，were TN／TP，NH4-N，NO3-N，TN，TP，SD，water depth，pH，phytoplankton，water temperature，zooplankton，DO and NH3-N，TN／TP，TN，TP，NO3-N，water depth，pH，zooplankton，phytoplankton，water temperature，DO，SD，respectively；The ratiol of TN/TP in Maolihu Lake and Xihu Lake were 15.35±5.71 and 9.92±1.97, respectively，which were regulated to a preferable condition by means of artificial fertilization，and meet the breed and growth requiments of phytoplankton. |
