  1. In recent years, the water - saving and control irrigation technique of rice has diverted from plot experimental and demonstration to lare scale. and has got remarkable economic and social benefits. amed at the characteristics of this irrigation area, optimal selection for water - saving techniques of rice, deciding the amout of leaching water and irrigation modles, investigating the adaptability of the water - saving and control irrigation technique in saline land. studying the increase in production mechanism of the technique are important to extend the technique, to better and develop saline land as well as slick spots. according to the results of field experiments, optimization study was conducted on the water - saving irrigation technique of rice in saline land, the effects of different water - saving irrigation techniques on the physiological indexes and yield of rice were systematically analyzed. by using mutiplepurpose fuzzy optimization method, better. water - saving irrigation technique was selector out, that is. the control irrigation technique in rice. the mechanism of it was analyzed from the aspect of the physiological and ecological saving water of rice to provide the implemental process and technical point ; throgh the quantitive analysis and comparision on control irrigation and control class ( flood irrigation ), high production and quality mechanism of the technique was analyzed in terms of physiology indexes of rice, the variation of soil moisture, the pest resistance and the lodge resistance, the change of soil temperature in paddy fields. the yield constitutive factors, the quality of rice and so on. in saline land. control irrigation and intermittent leaching modles were adopted to validate the adaptability of the technique in irrigation of rice in saline land, to analyze rice ' s physiological - ecological indexes and the change of soil salt content under the conditions of control irrigation leaching of rice and and to provide control irrigation and combined modle of intermittent leaching to adapt to different conditions

    本文從試驗及試驗資料入手,取得以下主要成果和結論:對鹽堿地水稻節水灌溉技術進行優化研究,系統地分析了不同節水灌溉技術對水稻生理指標及產量的影響,採用了多目標模糊優化的方法,對灌水技術進行綜合評判,優選了節水灌溉技術,論證該地區宜採用水稻控制灌溉技術;闡述控灌技術通過調節和控制水稻的需水規律,降低水稻高產情況下的無效水量消耗,從水稻生理、生態節水兩方面分析了控灌技術節水機理,針對性地總結出水稻各生育期實施節水控灌技術的步驟及技術要點;通過控灌與淹灌的定量對照比較,從根系、莖蘗、冠層葉片及綠葉動態到株高,土壤水分變化,抗病蟲害、抗倒伏能力,稻田土溫變化,產量構成因素及稻米品質等諸多方面進行動態比較,分析控灌技術高產優質機理;在鹽堿稻地採用控制灌溉+間歇淋洗模式,跟蹤測試田間水鹽變化狀況,驗證控制灌溉技術在鹽堿地區水稻灌溉中應用的適應性,通過分析水稻控制灌溉淋洗條件下水稻生理生態指標,提出優化控制灌溉+間歇淋洗組合模式,為進一步在高礦化度地區試驗水稻控灌技術奠定基礎。
  2. So studying the changing of university man in psychology and moral standard are becoming more and more important in educational fields. through documentation, questionnaires, demonstration, this thesis investigates the present situation and the developmental trend of the network information, as well as social behavior and psychology of university man

  3. Transportations give convenience and make huge value to people, at the same time they take transportation accident and environment pollution which has been in the catastrophical level. transportation catastrophe brings the losing life, property and the broken environment which are taken by transportation accidents and negative effects of the transportation activity. the essential character of the transportation catastrophe is sociality. the existing researches divide the transportation accident and transportation pollution into two different fields and seldom study the formation mechanism of the transportation catastrophe and forewarning countermeasure on the viewpoint of catastrophe and social management. based on the viewpoint of catastrophe, macromanagement and integrated the road and water transportation catastrophe which its frequency are higher among the transportation, this paper sets up the forewarning management system of carrier in the transportation catastrophe to find a principle and method of the effec tive defending transportation catastrophe and reducing catastrophe losing by using the methods of association theory with demonstration investigation, the theory of system, forewarning management and countermeasure theory. this paper try to offer a new theory and application approach

    現有研究把交通事故與交通污染割裂開來研究,鮮有從災害的角度和社會層面來系統研究交通災害的致災機理與防範對策。本論文從災害和宏觀管理的研究層面,針對交通運輸中發生事故與環境污染頻率較高的公路、水運交通運輸活動,綜合災害學、系統理論、預警管理理論以及對策學理論,採用理論與實證相結合的方法,研究交通災害中載運工具的致災機理及其預警管理系統的構建,尋求有效預防交通災害和降低災害損失的原理與方法,試圖在交通災害治理方面提供新的理論和實踐方法。本論文以發生交通災害的致災要素? ?載運工具為研究對象,通過公路、水運交通中車輛、船舶造成交通災害的成因、表現特徵和擴展規律的研究,構建了交通災害中載運工具的致災機理模型。
