一般情況下,水資源的變化主要受氣候變化和人類活動的影響,但在位於我國西北內陸乾旱地區的中高山地帶,徑流的形成主要受前者的影響.甘肅省的河西內陸乾旱區是該省重要的工農業生產和經濟開發區,這里各項社會和經濟活動與出山徑流的變化都有著十分密切的關系.因此,筆者根據有關水文氣象臺站的降水、氣溫和徑流觀測資料,分析了以黑河、昌馬河、西營河等主要河流為代表的河西內陸區出山徑流的變化特徵與規律.結果表明,河西內陸區出山口徑流的季節變化主要受地理位置和河流補給來源的影響,而年際變幅則受山區降水量年際變化及變幅的影響十分明顯.目前,梨園河以西河流水量處于上升階段,梨園河以東的河流則處于下降的階段;以黑河幹流鶯落峽水文站年徑流為代表的走廊中部地區的出山口徑流正處於1990年開始的枯水段的上升段.但總體而言,河西內陸乾旱區出山口徑流的變化相對比較穩定.預計今後若干年內,河西內陸乾旱區東段河流出山口徑流的變化以偏枯為主,中段、西段河流出山口徑流的變化以平水或平水偏豐為主Based on existed achievements of the continental river of arid area, the paper system analysis hydro - eco characteristics, hydro - eco changes and watershed changes. a case in tarim river, the paper study hydro - eco characteristics, river evolution, evaluated eco - environment quality, explore ecology water demand, study the rational utilization of water resources in tarim river watershed. the paper is composed of nine chapters, chapter 1 include research background, main research contents, research methods and research, meaning

中國是全球少數幾個同時受臺風風暴潮和溫帶風暴潮危害的國家之一,風暴潮災一年四季,從南到北均可發生.本文基於中國沿海近50年風暴潮災時間變化和空間分佈特點的分析,著重探討了近500年全國及長江、黃河、珠江三角洲的歷史記錄和近50年實測風暴潮災發生頻次的變化及其與氣候波動的關系,並對未來全球變化背景下,中國沿海風暴潮災的變化趨向進行了討論.結果表明:近500年來,中國沿海的風暴潮災在氣溫較高的偏暖時段比氣溫較低的偏冷時段明顯增多.近50年實測臺風暴潮災的變化也是如此,而溫帶風暴湖的變化則與此相反.未來全球變化引起的登陸影響中國的熱帶氣旋頻次增加和相對海平面的上升,均將導致風暴潮災呈加重的趨向The paper puts forward an ecosystem and the consideration of grading management and planning of water used for ecology, approaches to the water resources issues related to 8 important aspects of water and ecologic security, property management of water resources and business accounting, water resources allocation management, management of water resources policies, management of water resources development and utilization, water used for ecology and carrying capacity of water resources, man - built meadows and water saving, protection, management and water use of semi - desert meadows on the border of oasis and puts forward important strategic countermeasures on sustainable development of oasis situated on the downstream of dry endorheic drainage based on the study of orientation and key points of ecological building of the oasis
