1) water deficit degree
相对蒸降差
1.
This article presented a new index(water deficit degree) based on traditional drought index.
在传统干旱指标的基础上,研究一种新的指标———相对蒸降差,该指标涉及到与大气降水、草地蒸发蒸散和土壤水分有关的因子,通过牧草供需水状况反映牧草受旱程度的一个指标。
2) The difference between transpiration and precipitation
蒸降差
1.
The difference between transpiration and precipitation(DTP) decided the supply and consumption of soil water.
蒸降差决定了对土壤水的补给和消耗,蒸降差与土壤水分变化呈相反趋势,生长季蒸降差对土壤水分的贡献最大。
3) Difference of precipitation to evaporation
降蒸差
4) difference between precipitation and evaporation
降水蒸发差
1.
The characteristics of temporal and spatial variation of precipitation,evaporation and difference between precipitation and evaporation in four regions of North China are analyzed by using the daily observed precipitation and temperature data at 80 observational stations in North China during 1951-2000.
利用华北地区1951~2000年80个观测台站的降水、气温的逐日观测资料分析京津唐地区、华北西部、华北中南部和胶东半岛地区降水、蒸发和降水蒸发差在1951~1965年、1966~1976年和1977~2000年3个时期年代际变化特征。
5) Relative evapotranspiration
相对蒸散
6) Ralative evaporation
相对蒸发
