利用2001、2007—2009年监测的溶氧量资料和有关气象资料,对银川市鱼塘溶氧量与气象要素的关系进行了相关分析。结果表明,溶氧量随温度升高而增加,到一定程度后,又会减少,在16℃时溶氧量最大;溶氧量随相对湿度升高而减少;溶氧量随02时气压、风速、光照时数升高而增加。采用逐步回归方法建立了溶氧预报方程,划分了鱼塘浮头级别,经天气形势补充订正后,可较好地预报鱼塘浮头,从而达到科学饲养、趋利避害的目的。

Using monitoring dissolved oxygen content data in the year of 2001,2007,2008 and 2009 and meteorological data,the relationship between dissolved oxygen and meteorological elements was analyzed.The result showed: the dissolved oxygen content increased with the increase of temperature and to a certain degree and then decreased,the maximum was at 16℃;the dissolved oxygen content decreased with humidity increased and increased with rising of pressure,strengthening wind speed and length of light hours.The dissolved oxygen forecast equation was established by means of progressive regression and divided floating head levels of fish in pound.After the supplement correction of weather situation,the happening of floating head of fish in pound could be predicted so as to achieve the goal of scientific breeding.
