摘要:

对某入海河口在春季和夏季进行2次水体环境因子（TP、TN、COD、Chla、SS）监测，利用ArcMap扩展模块中反距离权重插值模型，对各监测值分别进行插值分析。通过插值结果，对营养盐、Chla、COD和SS在时间和空间上的差异进行探讨，揭示了入海河口水体环境因子在季节差异和流域分布上的独有特点。

Study on the Environment of Estuarine Water by Inverse Distance Weighting Interpolation

Abstract:

The environmental factors (TP、 TN、COD、Chla、SS) of some estuarine water were monitored twice in spring and summer. Each monitoring value was analyzed by inverse distance weighting interpolation in the ArcMap expansion module. Through the interpolation results， the spatial difference in time and space of the nutrients， Chla、COD and SS were analyzed. The unique characteristics of estuarine water environmental factors in seasonal difference and the distribution of river basin were revealed.
