摘　　要：根据下蜀生态定位站内三种林分和一片空旷地中１９８８年１月～１９９６年１２月的日蒸发量测定资料，对林内外蒸发量进行了研究，结果表明空旷地无雨日蒸发量比林内多１～４倍；就三种林分相比无雨日蒸发量是松林＞栎林＞杉林，但差值至多７０％。同时也讨论了林内雨日蒸发量测定失真的原因。The daily evaporation at four observation stations (three stands and an open field) was studied in Xiashu Forest Ecological Station from 1988.1 to 1996.12.The results showed that evaporations of the open field were 25 times as large as that of the stands. Among the stands the evaporations in the non_rainy days in:Chinese fir forest <oak forest <loblolly Pine forest, but the differences were not more than 70%. In addition, the reason of fault records of rainy days evaporation at stands was discussed.
