The main points of hlsip quality control includes : during the design stage, it is necessary to control the scheme comparison and optimum design, esp. the waterwork, electromechanical device and irrigation region planning, to improve the design quality and pay attention to control the long - term benefits of design results ; during construction period, the supervisor should help proprietor choose construction contractor, sign the construction contract, supervise the manufacture of equipment and strictly execute the quality control procedure to subject the construction to controlled mode ; in addition, the contractors must improve their quality self - control, maintain the notion " quality first " and insist the full process, multiway, and multi system control of construction quality
高揚程梯級提水灌溉工程質量控制的重點包括:設計階段控制好方案對比、設計優化,特別是水工建築、機電安裝、灌區規劃等多專業多目標的確定和協調,提高設計質量和深度,注重控制設計成果的長期效益;施工階段協助業主選擇好施工承包商,制定出嚴謹、完備的施工合同,搞好設備監造,嚴格執行質量控製程序,使工程施工時時處于受控狀態;同時要提高承包商的質量自控能力,堅持施工質量的全過程、多方法、多體系控制。The main issues of the research are put as following : firstly, with the international comparing of market sharing rate and trading competitive index, it was revealed that wheat in china has inferior international competitiveness with a bit rising during current years, however, which is still behind that of the main wheat export countries. secondly, after the international comparing of the main factors that affect the international competitiveness of wheat, it was discovered that chinese wheat has the obvious cost advantage on unit product, while because of the high circulation fee, it results in inferior advantage on the price ; low and unstable quality is another factor which leads to inferior wheat competitiveness ; the input of fertilizer and labor makes little impact on the productivity of chinese wheat, while the input of seeds, irrigation and machine makes a strong impact, so it should be more invested in seeds, irrigation and machine to reduce wheat ' s unit cost. the assistant industries of the wheat, such as breed, production materials and processing industries, have inferior international competitiveness and lagged development
其次,通過對影響小麥國際競爭力的主要因素的國際比較發現:中國小麥單位產品生產成本具有明顯優勢,但由於較高的流通費用,導致在價格上不具有優勢;小麥質量較差、品質不穩定是導致中國小麥國際競爭力較低的主要因素;生產要素中化肥和勞動力投入對中國小麥生產力水平的影響程度較小,而種子、灌溉和機械投入對小麥生產力水平的的影響程度較大,因此小麥生產投入要以增加種子、灌溉和機械的投入為主,代替大量的化肥和勞動力投入,進一步降低小麥單位產品成本,增強中國小麥國際競爭力;中國小麥的上下游輔助產業(包括品種資源、生產資料和加工業)的國際競爭力較弱,發展較為滯后;中國小麥生產者的組織化程度較低嚴重製約了中國小麥質量的提高、流通費用的降低和加工業的發展;小麥生產經營活動本身的特點決定了在充分發揮市場機製作用的基礎上,必須通過政府的宏觀調控來克服其市場機制的失靈,保障市場機制有效運行,但通過國際比較研究發現:中國政府在生產者支持、市場體系建設和國際貿易政策上對小麥的支持水平較低,與提高中國小麥國際競爭力的要求有較大差距,尤其是較低的生產者支持水平和市場體系建設程度制約了中國小麥國際競爭力的提高。The advanced irrigation web, the scientific and reasonable use of water, and the strict and perfect administration were the most striking characteristics of the utilization of water resource in dunhuang area during tang and five dynasties. it supplied the necessary condition for the existence and development of the oasis agriculture in this area
發達的灌溉網路,科學合理的用水方法,嚴格完善的管理制度構成了唐五代敦煌地區水力資源開發利用的重要特徵,為敦煌綠洲農業的生存和發展提供必要的條件。4. it showed that through analyzing the motive factors to farming system evolvement in past 50 years in inner mongolia : total agricultural machines, rural electric power, chemical fertilizer use, effective irrigation areas and species and cultivation techniques are factors to grain production, and these factors played different roles in different periods. among above factors, total agricultural machines and effective irrigation areas are the most important factors to total agricultural production values, and chemical fertilizer use, species and cultivation techniques ar
對農業總產值增長起最重要作用的是有效灌溉面積的擴大和農機總動力的增加,其次是化肥的使用量和良種及農作技術;全區主要畜禽生產資料及產品對農業總產值的影響因時間區段不同而異,生豬存欄數和牛及大牲畜存欄數對牧業總產值的影響最大, 1979年- 1991年,羊毛產量成為對農業總產值貢獻最大的因素, 1992年- 1998年,牛奶產量成為對農業總產值貢獻最大的因素。After we built waterpower - electricity station, we can strengthen flood - preventing ability of downstream, improve the condition of farmland irrigation and town - supplying and region environment and so on. exploitation extent of waterpower resource is an important symbol of scientific and technical advancement and economic development

本文採用因素法定量化評價各地塊定級單元的相關性和權重性,最終選定了有機質含量、土層厚度、土壤質地、鹽堿化程度、排水能力、灌溉保證率、防護林完整度、條田平整度、中心區位,土地利用方式等因子作為定級的指標,使用了加權加和因素法進行了的定級計算,逐步完成了農用地質量情況的評價,劃分出了級別。But on the later condition the trend of accumulation turned to be stable in the w3 treatment ( vseawater / v pure water = 1 ) - in root zone soil, variation of sar value accorded with total salt accumulations and sometimes decreased at the treatment where the v seawater / v pure water > 1. contents of cl - and na + which were the main ions and leached obviously in 0 - 60cm soil were greatly influenced by rainfall, but the rainfall did not affected the contents of ca2 +, mg2 + and k + whose ability of leaching is worse than that of cl - and na + in the root zone soil obviously. the vertical distribution of salt ions in the 0 - 60cm soil were mainly affected by the ratio of v seawater / v pure water in the irrigation water on the condition of not enough rainfall, but on the cont
海水灌溉下,耕層土壤中鹽分含量受降雨量影響很大,足夠的降雨條件下,鹽分不會積累,降雨量較低時,鹽分積累明顯,但在50海水處理下趨于平衡狀態;耕層土壤sar值的變化情況和鹽分含量變化情況相一致,在灌溉水中海水濃度大於50時有所下降;土壤中主要鹽離子為cl ~ -和na ~ + , 0 - 60cm土層內, na ~ + 、 cl ~ -明顯的向土壤底層遷移,其在土壤中的含量受降雨影響顯著,而ca ~ ( 2 + ) 、 mg ~ ( 2 + )和k ~ +在土壤中遷移能力較低,其含量受降雨影響較小; 0 - 60cm層次土壤鹽分的縱向分佈在降雨量較低的條件下主要受灌溉水中海水濃度的影響,而在降雨充分的條件下,地面覆蓋程度成為重要的影響鹽分和水分脅迫下菊芋的生理響應及其海水灌溉研究因子之一。Water delivery has been run over 30 years. the main canal has the problem that the actual conveying capacity is very low now and the conveying capacity of the east - one main canal i only half of the design value, this lead to guaranteed real - time efficiency of the irrigation of the farmland recede greatly. the downstream has no water and crops were drought to death have been seen more times in the irrigation period, this lead to the contradictory between the upstream and downstream on water usage, moreover, the lower discharge capacity of the dry canal in irrigation period is the main cause of the actual irrigated area is only half of the design value
經過三十年的輸水運行,目前乾渠工程存在嚴重的輸水能力低問題,其中東一乾渠輸水能力只能達到原設計的1 2 ,使農田的適時灌溉保證率大大降低,多次發生灌溉期下游見不到水而旱死莊稼的情況,造成上下游用水矛盾突出,而且灌溉期乾渠過流能力偏小,是導致實際灌溉面積僅為設計值的1 3的重要原因。But currently a huge amount of sediment deposited there has caused severe problems and need to be dredged. dredging is one of the effective engineering measures to control floods and improve navigation, irrigation conditions and environment
