| 摘 要： | 通过水面蒸发观测资料分析，提出林网内相对蒸发变化可用分段曲线拟合，分为对数区与二次曲线区两部分．对数区相对蒸发变化服从对数规律ＥＡ／Ｅ０＝ａ１＋ｂ１ｌｎｈ，二次曲线区相对蒸发变化服从二次曲线规律Ｅｈ／Ｅ０＝ａ２ｈ２十ｂ２ｈ＋ｃ．在蒸发水平分布特征研究基础上，对林网内平均相对蒸发强度进行了估算，并讨论了保水性能最佳防护林带距间题．

| Abstract: | In this paper,the data on water surface evaporation are analysed. The change of relative evaporation in windbreak network can be fitted by segmental curve, which includes two parts:the logarithmic one obeies natural logarithmic rule Eh/E0=a1 b1lnh,and the second-degree curve one obeies second-degree curve rule,Eh/E0=a2h2 b2h c.Based on the characteristic study of horizontal distribution of evaporation,the mean relative evaporation intensity in windbreak network is estimated and the optimum distance space of sheltbelts for water reserve is discussed. |
