水年 meaning in English
year， water
Examples
- Soil water storage decreased on the whole in summer and autumn during drought year , but increased during rainy year
干早年，夏秋以失墒为主，土壤水分处于负补偿;丰水年，夏秋以增墒为主，土壤水分处于正补偿。 - It is found , through further study on the water temperature distribution in the high flow year , the low flow year and the cold year , that the influences of discharge and weather are limited on the water tem
又就丰水年、枯水年和低气温年的水温分布作的进一步研究发现，水量和气象条件对大型深水温结构影响有限，其水温结构具有较强的稳定性。 - Comparing with the average amount of water diverted from the yellow river , it shows that the distributed water for huimin is abundant , but that for wudi is short . the countermeasures that deal with the water shortage should be sought
由计算结果可见，按现状十年平均供水量和用水分配比例，平水年惠民供水充足且有富余，而无棣缺水较多，必须为此寻求对策以满足需要。 - We found that the higher midlayer and deeplayer water contents after harvest , the faster alfalfa grew , and , the more quickly covered the bare soil , the more soil evaporation restrained . in this way , the soil could sustain higher shallow soil water contents
即使在平水年和丰水年，在7月之前降水也不能满足苜蓿的正常生长需要，而在7月以后，降水量略大于苜蓿需水量，所以要获得高产必须进行灌溉。 - The precipitation frequencies is analysed according to 1956 ~ 2000 years of rainfall record series in baoding area . the features of distribution of rainfall are detailed evaluated . firstly , the distribution of monthly precipitation is not even . for instance . the annual rainfall amount is about 548mm in whole year , about 80 % of them in summer season . secondly , yearly variation of rainfall is greater . thirdly , the abundant years usually are followed by short years , but the important changes have taken place in the last decades . before 70 ' s the abundant years took the dominant position , from the 70 ' s to the middle of 80 ' s the short years took place more frequently than ever . after the later of 80 ' s , the short years hold the main position . the above knowledge is instructive for guiding the rainwater resources effective utilization
本文利用1956 2000年保定市的长系列降雨资料，对保定市降水量进行了频率分析、年内变化分析和多年变化分析，明确了保定市降水量年内、年际间的变化情况：保定市降水量年内分配不均，汛期( 6 - 9月)占年降水量的81 。保定市降水量年际间变化大，丰水年和枯水年交替发生， 70年代以前以丰水年段为主； 70年代到80年代前期降水量丰枯交替频繁，总的接近于枯水年段； 80年代后期至今以枯水年段为主。这种降水分布规律对农业生产雨水资源的高效利用具有重要的指导意义。
