  1. Owing to the effect of landform, the precipitation in the second stage of rain season is decreasing from the line of jingnan - yongchun - fuding to the northwest and southeast, the spatial distribution characteristics of other three rainy seasons and all year precipitation are decreasing from northwest to southeast

    除后汛期因受地形的影響，降水量由南靖-永春-福鼎一線向西北和東南兩邊減少外，其它三個雨季和年總降水量空間分佈大體上是從西北向東南逐漸遞減。
  2. 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，總的接近於枯水年段； 80年代後期至今以枯水年段為主。這種降水分佈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。
  3. It shows that the model is better and steadier on prediction capacity in the 7 - year experiments for rainy season precipitation

    通過青島汛期降雨量的7年預報試驗表明，該模型具有較為穩定的預報能力，值得進一步研究應用。
  4. ( 2 ) the effects of rainfall on the runoff and sediment in the weihe river are studied. it is pointed out that the rainfall is much less than the average. especially during the flood season, which results in the lower runoff yield

    （ 2 ）分析了降雨特點及對渭河流域水量的影響，指出90年代全流域降水量比多年平均值偏少，尤其汛期雨量偏少較多，因而同樣降雨條件下，產流量偏少。
  5. Finally, a qualitative graded prediction model - markov chain qualitative modeling, is established for above two precipitation series by using meteorological graded division criteria. the forecasting result is good

    論文最後還對年降水量、汛期雨量序列探討做分級預測，採用氣象分級辦法進行分級。結果表明所建立的馬爾柯夫預測模型具有較高精度。
  6. Through the statistics and analysis of runoff and amount of sand lost in the downstream of weihe in recent years, it is discovered that in the downstream of weihe the magnitude sand season was ahead of the main flood season relatively within the year ; variation tendency of annual runoff and amount of sand lost was identical basically, and the quantity of water and sand at huaxian gauging station was tailing - off continuously from the 1960 to 2005 ; there was direct relation between the situation of rushing or silting deposits and rainfall at this section of the river : the river depositing in the year which is rich rainfall, the eroding in the poor rainfall

    摘要本文通過對近6年渭河下游水沙量數據的統計和分析得出，渭河下遊河段年內多沙期較河流主汛期有所提前；年徑流量和年輸沙量的變化趨勢基本一致，而且自60年代至2005年華縣站的水沙量持續呈遞減趨勢；河流的沖淤情況與該河段的降雨量有著直接的關系，當年平均降雨量小的時候河流以淤積為主，當年平均降雨量大的時候河流以沖蝕為主。
