Results show that the spatial distribution of the precipitation of the west is very uneven and obviously different in every quarter ; the characteristics of precipitation is droughty and less - rain in almost all part in winter. plentiful in summer, spring and autumn are transition phases, rainfall of autumn is more than that of spring in the most of region ; relative variability of each season rainfall is bigger than that of year, the variability is biggest in winter, but smallest in summer. alike between spring and autnmn and comprative in numerical value ; the area of least precipitation is in talimu basin and the northwest of chaidamubasin, not in the northwest of china
研究發現：西部地區年降水量的空間分佈極不均勻，局地差異大；冬季絕大部分地區乾旱少雨，夏季雨量豐沛，春秋季是過渡階段，大部分地區秋雨多於春雨；各季降水量的相對變率大於年變率，夏季最小，冬季最大，春秋兩季相似，數值上與冬季相差無幾；我國雨量最少的地區位於柴達木盆地西北部和塔里木盆地，並不在我國的最西北角。5 the dynamic of soil water content and salinity is significantly different among communities in ecotone. the soil moisture and salinity are two main factors that influence the distribution and succession of plant communities
5 、過渡帶各類型群落間土壤水鹽動態存在顯著差異，土壤水鹽的梯度變化是群落分佈和演替的根本原因。The community productivity, structure and succession are significantly influenced by global climate changes. this study focused on soil respiration rate of stipa baicalensis grassland by using dynamic infrared gas absorbed method. we analyzed diurnal pattern of soil respiration rate and the influences of surface soil temperature and water content for this parameter, then compared the differences between day and night soil respiration rates, and explored the correlations between aboveground and underground biomass with the soil respiration
溫帶的半乾旱、半濕潤區草甸草原屬于過渡氣候影響下形成的植被類型，對環境氣候條件變化十分敏感，為了揭示半乾旱、半濕潤區草甸草原生態系統土壤碳素釋放規律及其對主要環境因子的響應，本研究採用動態室紅外氣體吸收法測定松嫩草甸草原典型群落? ?貝加爾針茅群落土壤呼吸速率，分析了土壤呼吸速率日變化規律及表層土壤溫度和含水量對土壤呼吸速率日變化的影響，比較了土壤呼吸速率的晝夜差異，探討了地上生物量和地下生物量與土壤呼吸速率之間的相關關系。It ' s significant to further the study of the environment evolvement and forming mechanism, and this helps to open out its ecological essential, protect and develop the oasis, lacated in the cross belt which converge northeaster and northwester, yutian oasis was threatened by the ilowing sand, and has the bad nature conditions the main purpose of the paper is applying fractal theory to research on the change of transitional belt between oasis and desert, which is a typical ecosystem in arid zone
而荒漠與綠洲之間的植被帶即過渡帶則最為敏感、完整地記錄了這兩大生態系統之間的相互作用與相互轉化，深入研究這一特殊地帶的環境演變過程、特徵及形成機制對于揭示其生態學實質、維護和發展綠洲具有重要的實踐意義。於田綠洲位於東北風與西北風的交匯地帶，受到流沙侵蝕的危害很嚴重，自然條件非常惡劣，生態環境異常脆弱，人民的生存環境受到了很大的威脅。It uses the encouragement of step wave or other impulse current field source to produce the transition process field in earth. in the moment of shutting the power it produce the volute alternating electromagnetic field. from the abnormity of measuring the attenuation character of the second induction electromagnetic field, which produced by underground medium with time change, the conductive capacity and the position of the underground non - homogeneous substance can be analyzed
瞬變電磁法（ transientelectromagneticmethod ）是一種時間域的電磁勘探方法，利用階躍波或其它脈沖電流場源激勵，在大地產生過渡過程場，斷電瞬間在大地中形成渦旋交變電磁場，測量這種由地下介質產生的二次感應電磁場隨時間變化的衰減特性，從測量得到的異常分析出地下不均勻體的導電性能和位置，從而達到解決地質問題的目的。Wavelengths or scales of surface heterogeneity are less than 20km. simulation results show that cbls do reach a quasi - stationary state correspondent to specified surfaces, after a long enough evolution. in this transition process and after that, horizontal statistics, i. e. mean potential temperature and vertical heat - flux, show profiles little differences to those over homogeneous flat surface. main effect of surface heterogeneity is to increase kinetic energy in cbl and the increase concentrates in the direction of surface heterogeneity. the time of cbl spent to reach its first peak of mean kinetic energy,
模擬結果表明，在充分長的時間后，邊界層達到一種適合於地面條件的準定常態。這種準定常態和向其過渡的過程中，水平平均的邊界層廓線性質，如平均位溫廓線垂直熱通量廓線等幾乎與平坦均勻地面的結果相同，或差異極小。地面非均勻性的主要作用是使邊界層動能增大，並以地面非均勻性變化方向的動能增加為主。分享友人
