潜在蒸散 meaning in Chinese
potential evapotranspiration
Examples
- Model on wheat potential evapotranspiration in apple - wheat intercropping
小麦复合系统小麦潜在蒸散模拟模型的研究 - 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
选择适合的“潜在蒸散”和“湿润环境蒸散”的估算式,利用相对潜在蒸散量指标,相对实际蒸散量指标及流域湿润度,通过数据集群技术,完整模拟并展现了蒸散互补相关关系。 - 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稳的、无周期,其时空变化与径流、蒸发、潜在蒸散和土壤水分的关系表明,气候干燥和严重的荒漠化不是由于降雨量减少直接引起,龙羊峡水库对共和盆地年降雨量变化没有影响;但是年气温序列是非平稳的,茶卡、恰卜恰和贵南的年气温平均每年升高0 . 0247 、 0 . 0422和0 . 0272 ,且气温升高2 ,年潜在蒸散增加57mm ,盆地内气候逐渐变干燥,但影响比较小;由于历年潜在蒸散序列是平稳的,因此气候变化对盆地的作物潜在蒸散的影响在研究期内是较小的。 - 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,历年潜在蒸散平均974mm ,各月潜在蒸散与降雨和温度之间是很好的正相关,所以雨热同季有利于作物生长:年潜在蒸散的空间分布范围从485 ? 1174mm ,平均1027mm ,而且年潜在蒸散空间分布与降雨和坡度是负相关,与温度和大气外层辐射正相关,因此水分和温度的是影响作物水分耗散的重要因子,决定了共和盆地植被的气候生产力。
