oasis effect
解釋
綠洲效應-
The water vapor content, in all, is relatively less over the gobi and hungriness and more over the oasis ; there is " the clothesline effect " which influences the stabilization and development of the oasis at the margin of the oasis or the long and narrow protection forest through the deserts or in the neighborhood of the river and the aqueduct
戈壁沙漠上空水汽含量相對較少，綠洲上空水汽含量相對較大；綠洲邊緣或通過沙漠的窄長護林帶、河流以及水渠附近，存在著影響綠洲穩定和發展的「曬衣繩效應」 。 -
Obtaining full and accurate information on the spot, basing on the fractal theory, fully using remote sensing image as the main research data and relative thematic map as reference data, aiding of pci which is a powerful image processing software of remote sensing technique, the land desertification and the change of transitional belt between oasis and desert in yutian county are analyzed quantificationally. the rational proposals are tabled for the desert controlling and area rebuilding in the future, furthermore, this paper deeply discusses and validates the effect of fractal approach applied in the desertification research
在實地考察研究區獲得翔實資料的基礎上，以分形為理論依據，充分利用多時相衛星遙感數字圖像為主要資料源，參考相關資料，藉助遙感圖像處理分析軟體pci操作平臺，定量分析評價於田縣的沙漠化狀況及綠洲?荒漠交錯帶的演變趨勢，為今後沙漠化的控制、改造工作提出合理化建議，並對分形理論在綠洲?荒漠交錯帶定量研究中的作用作深入地探討和驗證。 -
The premises of the simulation are that the runoff from upreach is 7. 8 108m3 / a and the means of economization on water is in effect. when studied it was thought firstly the water for the lake area and the living plant of the oasis, then for forest - sod irrigation and farmland irrigation
模擬計算是以上游下泄水量7 . 8 10 ~ 8m ~ 3 a為前提條件，在實行節水措施，完善供水系統的情況下，首先滿足維持和恢復一定規模湖泊面積，保證綠洲植被正常生長所需水量，然後考慮林草灌溉用水和農田灌溉用水量。 -
There is a strong relationship between the vegetation cover and stability of oasis ecosystem which is the key location of mankind production and existence in arid and semi - arid land. the change of vegetation cover in arid and semi - arid has very important influence on the oasis eco - system, as it is very sensitive to the environment changes to oasis direction or to desert direction that the fluctuating index of vegetation cover. the vegetation cover rate change great effect on realizing the characteristic
植被覆蓋度對于乾旱區人類生存和生產核心場所的綠洲穩定有著直接的關系，在乾旱區覆蓋度的變化對本已脆弱的綠洲生態系統有著重要的影響，是向綠洲化還是向荒漠化的方向發展，十分敏感於綠洲植被覆蓋度的指數，了解各類植被覆蓋度的特徵及演化規律，對認識乾旱區生態環境的現狀及發展趨勢，辨識引起環境變化的驅動力，有著重要的意義。 -
8 ndvi value in oasis is significantly higher than the value in desert, both of them have different rules in monthly variation. irrigation temperature and precipitation have effect on variation of ndvi in oasis, the correlation coefficients of sparse vegetation ndvi in desert with climatic and hydrological factors are insignificant and meaningless in practice. the drive factors of oasis ndvi are only adapted on oasis in arid land and are not fit to desert system in arid land
8 、綠洲ndvi值顯著大於荒漠，二者具有不同的季節變動規律；灌溉、氣溫和降水是綠洲ndvi變化的驅動因子，荒漠稀疏植被ndvi與綠洲氣侯、水文因子相關不顯著或無實際意義；綠洲ndvi的驅動因子只適用於乾旱區的綠洲區域，而不適用於乾旱區荒漠系統。 -
To reach the aim of reflecting entirely the degree of the effect, the general aim is decomposed with six aspects, which are water resource carrying capacity effect, surface water resource effect, groundwater resource effect, oasis and vegetation effect, soil salinification effect and land desertification effect
為了達到全面反映水資源開發引起的水土環境效應程度的目的，將總目標分解為水資源承載效應、地表水效應、地下水效應、綠洲及植被效應、土壤鹽漬化效應和土地沙漠化效應等6方面來進行描述。 -
Under the background of macroscopical climate change, the cultivated land increases and oasis area enlargement in the middle reaches makes more imbalance between supply and demand of water resource, which has caused certain negative effect on the ecological environment of the oasis in lower reaches. and it is the very important reason that causes the oasis in the lower reaches diminishing, the oasis systematic area of the whole basin atrophying, and the stability declining
在宏觀氣候變化的背景下，中游綠洲耕地的增加和綠洲面積的擴大使水資源供需矛盾更加突出，並對下游綠洲的生態環境造成了一定的負面影響，是導致下游綠洲萎縮，整個流域綠洲系統面積縮小穩定性下降的重要原因。
