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。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。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。In general, the annual rainfall in these regions is less than the annual water loss by evaporation.
總的來說,這些地區的年降雨量比一年內由於蒸騰而失去的水分要少。Based on the analysis of crop structure and crop yield according to the statistic data in 1949 ~ 2000 year. the total water consumption of main crops and the amount of rainwater utilized have been calculated. the rapid increase in water demand for crops production after the late eighties is the one of main reasons of the water resources crisis in baoding area. the efficient precipitation, the water demand and the deficiencies of main crops in different typical years and in different growth period in baoding plain have been studied in detail. the factors of water use efficiency of different crops have been put forward through the analysis of test data in typical year
本文利用保定市1949 2000年主要農作物的種植面積與產量統計資料,在分析了歷年種植結構變化、單產變化的基礎上,明確了歷年糧食總產變化情況,計算了歷年糧食生產的總需水量及其變化;根據農作物的雨水資源的變化規律,分析了歷年用於糧食生產的有效降水量;得出了保定市農業用水量從90年代中後期大幅度增加而有效降雨量的明顯減小,是造成保定市水資源供需矛盾突出的主要原因之一。The spatial and temporal concentration of chlorophyll a in the lake varied very strongly, the concentrations in the sites located in xin ' an river and effected by human activity were raised obviously from april to august, and were much higher than those in other sites. monthly average concentration for the lake has the same tendency as the rainfall
0月至次年的3月最低,千島沏個湖的葉綠素aff月平均濃度與月降雨顯變化趨勢極為相似:空間總體分佈卜,入湖口和易受人類活動影響的點位葉綠素a的含量明顯高於湖中心和出水口。( 4 ) according to analysis of water resources characteristics of the dam system, following conclusions are obtained : amount of yearly available water resources of the dam system presents uncertainty ; water resources utilization by the dam system should focus on fully utilization of rainfall, runoff and flood ; meanwhile, water resources exploration of the dam system should reach the objective of maximum economic benefit in years ; a modeling system for water resources utilization and exploration by the dam system is established on the basis of reasonable investment and above objectives
對壩系水資源的特點進行了深入研究,得出以下結論:壩系水資源年可利用量具有較大的隨機性;開發利用壩系水資源就是充分利用降雨和徑流洪水;壩系水資源開發應以多年經濟效益總體期望值最大為目標。同時引入了最佳水資源投入量的概念,並建立了壩系水資源開發利用模型。The results showed that there were 2380. 879 tons sediment - attached nitrogen, 10432. 959 tons soluble nitrogen, 40. 922 tons sediment - attached phosphorus and 295. 679 tons soluble phosphorus inputted into the qiandao lake per year. monthly inputted loading changed very strongly, the loading was interrelated positively with rainfall and 70 % of total pollutant was exported from the watershed during the april and september
千島湖流域氮、磷非點源污染的月輸入負荷差異極大,氮磷污染物的輸出量與月降雨量成正比,降雨集中的4 9月份是每年的污染物輸出集中時期,氮、磷污染物輸出量佔全年總量的70以上。分享友人
