摘要
根据１９８１～１９８６年计算结果，指出我国大陆上空拥有水汽资源年总量＋３３１８４．４亿３。暖季（４～１０月）＋３０４９４．１２亿ｍ３，寒季（１１～次年３月）＋２６９０．２８亿ｍ３。全年唯有气温最低的隆冬（１２～次年２月）是水汽资源亏耗（－７７３．６３亿ｍ３）季节，而夏季（６～８月）则是我国大陆上空水汽资源最关键的汇聚时期，资源量＋１８１９７．５６亿ｍ３。１６号、１４号边界分别是１１～５月水汽输入最大或次大边界；而６～１０月则是１３号与１６号边界。按进入我国大陆水汽量百分比分析，南海为第一水汽源地（暖季２５％、寒季４２％）；孟加拉湾、阿拉伯海为第二水汽源地（暖季２１％、寒季２９％）；亚洲北方大陆、欧洲大陆或海域分别为暖季（１６％）、寒季（１２％）第三水汽源地。
This paper based on the computed results for the period of 1981-1986 indicates that there are water vapour resources with annual total amounts to +33184.4×10 8m 3 over Chinese continent, of which +30494.12×10 8m 3in warm season (April to October) and +2690.28×10 8m 3 in cold season(November to March).Only the midwinter(December to February)is the dissipating season of water vapour resources (-773.63×10 8m 3)in which the temperature is the lowest in the year. Summer (June to August)is the key collecting period of water vapour resources for Chinese continent, and with mean seasonal value high up to +18197.56×10 8m 3.Boundary No.16 and No.14 is the maximal or secondary importing boundary of water vapour during November to March, but it is the No. 13 and No.16 for June to October. According to the percentage of inflow value of water vapour into Chinese continent, South China Sea is the first source of water vapour (25% in warm season, 42% in cold season);Arabian Sea and Bay of Bengal is the secondary source(21% in warm season, 29% in cold season); the third source is the Northern Asia continent for the warm season (16%) and Europe continent for cold season (12%).
