气象要素与池鱼泛塘关系研究

以山东省德州市区富营养型养鱼池为立论基础，研究气象要素与有机沉积严重鱼的溶氧关系。据１８年资料分析表明，水体溶氧含量与光照时数，强度和气压呈正相关，与气温，冰雪和大雾呈负相关。一和风力既能增氧，有时又起负作用。根据水体理化，生物因子与气象变化，采取综合防治措施，可有铲预防池鱼泛塘。

Studies on Relation between Meteorological Factor and Asphyxia of Pond Fishes

Based on the eutrophic ponds for fish culture in the urban district 0f DezhouCity,Shandong Province,the paper discussed the relation between the meteorological factorsand the dissolved oxygen in the ponds with the thick organic sediment. The result to analyzethe 18 years' data showed that the c0ntent 0f DO in the pond water is positirely correlatedwith the illumlnation hours and intensity as well as the atmospheric pressure,but is negatirely correlated w1th the temperature,ice,snow and heavy fog. Although rain and wind can playa role to increase DO in the pond,yet sometimes they can lead to the negative effect. According to the change of physical,chemical and biological factors and meteorological phenomenaand taken measures for integrated control,the asphyxia of fish in the pond can be efficientlyprevented.
