The activity of proteinase was correlated to organic matters and total nitrogen negatively , but opposite to dissolved inorganic phosphorus 与环境因子分析表明,蛋白酶活性与有机质、总氮呈负相关,而与溶解无机磷和沉积物粒径呈正相关。
In sununer , organic and inorganic phosphorus in sediment may iv abstract dissolve into he water body in the form of reactive phosphate to meet the demand of red tide biota N含量低的情况是甲藻类难以成为忧势种的主要原因。湖水中tin含量与浮游植物数量呈现出一定的负相关。
The activity of alkaline phosphatase was significantly correlated to the particle size and dissolved inorganic phosphorus negatively but opposite to organic matters and total nitrogen 通过直线回归分析发现,碱性磷酸酶活性与沉积物中粒径、溶解无机磷含量呈显著负相关,与总磷、有机质、总氮含量呈显著正相关。
Additionally , it was the precipitation process of suspended phosphorus that played a relative important role in phosphorus removal in cold periods , and that was adsorption / complexation of dissolved inorganic phosphorus in warm periods 此外,低温期悬浮磷的沉积作用除磷效率高;高温期溶解无机磷的吸收络合作用除磷效率高。
No matter what kinds of sample , including the horizontal and vertical , the activity of catalase was correlated to organic matter , total nitrogen and total phosphorus positively , but opposite to dissolved inorganic phosphorus and particle size of sediments 无论是水平还是垂直样品,沉积物过氧化氢酶活性与有机质、总氮、总磷呈正相关,与溶解无机磷和沉积物粒径呈负相关。
