摘要

本文之目的係在探討澎湖沿海地區，不同地形其高度及水平距離之風速，鹽分分布之關係，並分析各試區風速及鹽分之垂直高度，水平相對風速及水平相對鹽分之分布特性，以瞭解各試驗地區之風速及鹽分分布與地形特性之關係。所得結果如下：（1）各試驗地區之鹽分垂直高度，多呈對數分布。（2）試驗地區高程由高往內陸逐漸下降者，其水平距離之鹽分分布愈往內陸，其鹽分衰減量愈多。（3）試驗地區地形爲逐漸往內陸上升者，其水平距離之鹽分衰減量比其他地區少，相對鹽分大。（4）各試驗地區之鹽分衰減曲線比風速衰減曲線顯著。（5）在試驗期間各觀測點之空中飄鹽量與潮汐之漲，退潮，有顯著關係，漲潮時，空中飄鹽量多，且高度愈高，增加的量愈多。

The purposes of this thesis are that to study on the relationships between the wind velocity and salinity distribution with different topographical characteristics in .coastal area of Peng-Hu Islands. The results of this thesis are summarized as follow: (1) The salinity vertical profile follows the logarithm law. (2) The amount of the salt reduction are decreased with its distance from seashore for adverse slope coastal topography. (3) The amount of the salt reduction are less than the other area for positive slope coastal topography but it will possess more relative salinity. (4) The salt reduction curves are more significant than the wind reduction curves in field experiments. (5) The salt spray match with ebb and flow of the tide during observation period, i, e., the amount of salt spray are more when tide rising.
