摘要: 探讨了在沙坡头人工植被固定沙地上A级蒸发皿的应用及其影响要素。结果表明A级蒸发皿测定的水面蒸发量包含了温度、湿度和风速三大小气候要素,起到一个综合器的作用,同时提出了一组动用小气候资料计算水面蒸发量的公式,通过这一初步性的研究也使小气侯要素对水分平衡的影响有了一个比较清楚的认识。

关键词: 水面蒸发, 水分平衡, A级蒸发皿

Abstract: This paper deals with the application of A-evaporation pan and its affecting factors on sandy land fixed by artificial vegetation.The results show that the evaporation determined by A-evaporation pan involves three microclimatic elements:air temperature,humidity and wind velocity.In other words,it plays a synthetic vessel role.In addition,a set of formula for calculating the capacity of water surface evaporation was derived from microclimatic data.This will contribute to a better understanding of the influence of microclimatic elements on water balance.
