潛在蒸散
英文
potential evapotranspiration-
Model on wheat potential evapotranspiration in apple - wheat intercropping
小麥復合系統小麥潛在蒸散模擬模型的研究( 2 ) based on gaining the surface parameters, to compare to diversified retrieve model to choose optimal one to retrieve net radiance flux, soil heat flux and latent heat flux, which settle the groundwork to calculate the regional et
在獲取地表參數的基礎上，反復對比前人各種遙感反演模型，選擇最佳模型對長江三角洲的區域凈輻射通量、土壤熱通量、潛熱通量進行了反演，為計算區域蒸散量奠定了基礎。By thoroughly analyzing the concept of " potential evaporation " and " wet environment area evapotranspiration ", using index of comparatively potential evaporation and comparatively actual one, the complementary relationship between actual and potential evapotranspiration was testified entirely with data integration technique. 2
選擇適合的「潛在蒸散」和「濕潤環境蒸散」的估算式，利用相對潛在蒸散量指標，相對實際蒸散量指標及流域濕潤度，通過數據集群技術，完整模擬並展現了蒸散互補相關關系。Annual precipitation series about 50 years is stable and no period ; further, the climate drying and desertification are n ' t caused directly by the decrease of precipitation during the period of the research according to the relational analysis among precipitation temporal - spatial change, runoff, evaporation, potential evapotranspiration and soil water ; longyangxia reservoir which was built in 1986 does n ' t have influence on precipitation up to now ; but annual temperature series in gonghe is unstable, having a linear upward trend, and it increases about 0. 0247, 0. 0422 and 0. 0272c per year, and temperature rise must be having an influence on desertification, but there is a very little temperature change, so that the effect is very small ; annual potential evapotranspiration series is stable too, so climate change has little influence on plant water consumption. 2
在青海共和盆地，近50年的年降雨量序列是平穩的、無周期，其時空變化與徑流、蒸發、潛在蒸散和土壤水分的關系表明，氣候乾燥和嚴重的荒漠化不是由於降雨量減少直接引起，龍羊峽水庫對共和盆地年降雨量變化沒有影響；但是年氣溫序列是非平穩的，茶卡、恰卜恰和貴南的年氣溫平均每年升高0 . 0247 、 0 . 0422和0 . 0272 ，且氣溫升高2 ，年潛在蒸散增加57mm ，盆地內氣候逐漸變乾燥，但影響比較小；由於歷年潛在蒸散序列是平穩的，因此氣候變化對盆地的作物潛在蒸散的影響在研究期內是較小的。According to the regional evapotranspiration analytical expression of heterogeneous soil surface applicable to moist climate region which is put forward in this paper, on one hand, soil water absorption is calculated under the consideration of the hydrological condition and hydraulic characteristic of soil surface ; on the other hand, using improved k - b model which is based on penman formula, the potential evaporation power is calculated
基於本文所提出的適用於濕潤氣候區非均勻地表的區域蒸散率解析表達式，一方面，充分考慮土壤表層水分狀況和水力學特性，計算土壤水分吸附力；另一方面，又充分考慮大氣條件，引進以penman公式為基礎的k - b模式（加以改進）計算潛在蒸發力。Temporally, annual potential evapotranspiration is from 882 to 107 lmm, with a mean value of 974mm at qiabuqia ; and it is positively correlational to precipitation and temperature, so it is beneficial for plant growth because precipitation and heat ocurs at the same growth period. ; spatially, annual potential evapotranspiration is from 485mm to 1174mm, with a mean value of 1027mm, and it ' s spatial distribution is negatively correlational to precipitation and slope, whereas positively correlational to temperature and extra solar radiation, therefore the spatio - temporal difference of water become the key factors to plant growth and plant climate potential productivity
在青海共和盆地，歷年潛在蒸散平均974mm ，各月潛在蒸散與降雨和溫度之間是很好的正相關，所以雨熱同季有利於作物生長：年潛在蒸散的空間分佈范圍從485 ? 1174mm ，平均1027mm ，而且年潛在蒸散空間分佈與降雨和坡度是負相關，與溫度和大氣外層輻射正相關，因此水分和溫度的是影響作物水分耗散的重要因子，決定了共和盆地植被的氣候生產力。分享友人
