摘  要:
利用潜江市水产局水温资料和潜江市气象站2018年的逐日气温资料,分析了潜江市虾稻共作地虾沟水温变化规律及其与气温的关系,筛选出与水温预报关系密切的气温要素,分季节建立水温预报模型,并对建立的水温预报模型模拟值与实测值做了模型误差评价。结果表明:虾稻共作地虾沟水温的变化主要是随气温的变化而变化,但水温的年变化幅度远低于气温。一年中,除了2月和3月的气温高于水温外,其余月份的水温都高于气温,任何季节的平均水温均高于气温。水温的日变化幅度较小,水温的日较差远小于气温的日较差,水温的小时最高、最低值出现时间均滞后于气温。水温与当日、前1日、前2日的气温相关系数较大,以气温为预报因子,建立的春夏秋季平均水温、最高水温、最低水温预报模型的预报值与实测值相关系数分别达到0.9110~0.9492、0.8643~0.8741、0.9555~0.9638,具有较高的精度,各季节预报模型平均水温、最高水温、最低水温模拟结果与实测值均低于±2℃,模拟效果较好,水温预报模型能为虾稻共作小龙虾养殖气象服务提供较准确的水温预报,从而为小龙虾科学养殖提供参考依据。

摘  要:
Based on the aquatic data and temperature data of Qianjiang City in 2018, the relationship between water temperature and air temperature was analyzed in the ditch of prawn-rice farming system. The water temperature forecast factors of temperature were screened out. Seasonal water temperature prediction model was established, and the error evaluation model of simulated values and the measured temperature was made. The results showed that the change of water temperature was mainly along with the change of air temperature, but the annual change of water temperature was much lower than that of air temperature. In a year, except for February and March when the air temperature was higher than the water temperature, the water temperature in other months was higher than the air temperature, and the average water temperature in any season was higher than the temperature. The diurnal range of water temperature was small, and the diurnal range of water temperature was much smaller than the diurnal range of air temperature. Before the water temperature and the same day, the temperature of 1, 2 days before the correlation coefficient was bigger. Based on the temperature forecast factor, The correlation coefficients between the predicted value and the measured value of the average water temperature, maximum water temperature and minimum water temperature in spring, summer and autumn reached 0.9110~0.9492, 0.8643~0.8741, 0.9555~0.9638, with high precision. The measured value and the predicted value of mean temperature, maximum temperature, minimum temperature in the seasonal forecast model were lower than ±2 ℃. The simulation effect was good. the water temperature prediction model could provide more accurate temperature forecast for the weather service of crayfish breeding with shrimp and rice, and provide the reference basis for the crayfish science breeding.
