    干早年,夏秋以失墑為主,土壤水分處于負補償;豐水年,夏秋以增墑為主,土壤水分處于正補償。
  • 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
    又就豐水年、枯水年和低氣溫年的水溫分布作的進一步研究發現,水量和氣象條件對大型深水溫結構影響有限,其水溫結構具有較強的穩定性。
  • 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
    即使在平水年和豐水年,在7月之前降水也不能滿足苜蓿的正常生長需要,而在7月以后,降水量略大于苜蓿需水量,所以要獲得高產必須進行灌溉。
  • 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年保定市的長系列降雨資料,對保定市降水量進行了頻率分析、年內變化分析和多年變化分析,明確了保定市降水量年內、年際間的變化情況:保定市降水量年內分配不均,汛期( 6 - 9月)占年降水量的81 。保定市降水量年際間變化大,豐水年和枯水年交替發生, 70年代以前以豐水年段為主; 70年代到80年代前期降水量豐枯交替頻繁,總的接近于枯水年段; 80年代后期至今以枯水年段為主。這種降水分布規律對農業生產雨水資源的高效利用具有重要的指導意義。
  • The outcomes show that the two methods can separate the basin pollution load from different sides , the two separation results are close to each other and can be provided as references for drafting pollution prevention policies and ; the proportion of the two pollution loads in the basin is more or less the same , point source is slightly heavier in a dry year and the proportion of non - point source pollution is greater in a wet year
    結果表明,兩種方法可以從不同的側面分別對流域污染負荷進行分割,且兩者分割結果相近,可以為流域污染防治政策的制定提供參考;流域內兩類污染負荷所占比重大體相當,枯水年點源污染比重略高,而豐水年非點源污染比重較大。
  • The runoff has been created in mountain and waters or neighboring regions , and it is 90 percent of the total in rainy season ; the total amount of precipitation is 7 . 08x109m3 in accordance with real amount , about 6 . 46 x 109m3or so , and it is 9 . 06 x 109m3in the rainy years , 5 . 66 x 109m3 in the drying years . there is 3 . 46 x 109m3 difference between them . so precipitation has a great influence on runoff
    在青海共和盆地,降雨產流主要在山區和水域附近,而且雨季產流占總徑流量的90 ;盆地降雨的總產流量為7 . 08億m ~ 3 ,豐水年為9 . 06億m ~ 3 ,枯水年為5 . 66億m ~ 3 ,因此徑流量受降雨量年變率的影響很大。
  • The results are as follows : ( 1 ) if we increase the pumping water by 493 x 104m3 , the amount of leakage recharge of rubber dam will rise by 231x 104m3 ; which indicates pumping by rubber dam can excite much more surface water infiltrate so as to supply groundwater . thus the utilization ratio of water source is increased , and it provides the reliable guaranty for enough supply of the groundwater storage in wet year . ( 2 ) under the condition of present status , the groundwater exploitable resource in wet year is 3670 104m3
    最后,通過數值法反復調算計算出本區地下水的允許開采量,計算結果表明,在現狀開采的條件下,大沽河地下水庫豐水年( p = 20 )時地下水允許開采量為13670 10 ~ 4m ~ 3 ,平水年( p = 50 )時地下水允許開采量為12054 10 ~ 4m ~ 3 ,枯水年( p =加% )時地下水允許開采量為10951xl了砰。
