摘　　要：根据二级湖闸站等四处蒸发站各类型蒸发器（皿）历年逐月水面蒸发观测资料和两处蒸发实验站分析的各类型蒸发器（皿）月蒸发量折算系数，推求出南四湖１９５３年１月至１９９０年１２月逐月及全年水面蒸发量，根据五处水位站历年逐月平均水位观测资料推算出南四湖历年逐月平均和全年平均水面面积，从而求得南四湖历年逐月和全年水面蒸发水量，并对水面蒸发量在时间上的变化特征作了分析。同时根据七处雨量站历年逐月降水资料计算了南四湖区面平均月、年降水量，并分析了水面蒸发量对水资源量的影响。其分析计算成果可供南四湖水平衡研究和水资源评价使用。Based on the data in every month of years observed with various types of evaporation pans at 4evaporation stations such as Erjihuzha Station,and the monthly evaporation reduction coefficients of various typesof evaporation pans analysed at 2 evaporation experimental stations, the monthly and annual free surface evapora-tion of the Nansihu Lake from Jan。 1953 to Dec。1990 have been calculated.According to the monthly observedaverage stages from 5 stage gauging stations in some years,the monthly and annual average water surface area canbe worked out,and the amount of monthly and annual free surface evaporation can thus be obtained, and thechanging characteristics of free surface evaporation in time can be also analysed.Meanwhile,according to themonthly rainfall data in the years from 7 rain gauge stations,the mean monthly and annual precipitation on thesurface of the lake have been calculated the influence of free surface evaporation on water resources is also analysed.The analysis and calculation results of this can be used in the water balance study and water resourceseva1uation of the lake.
