建議

1、未來 TDR 感測器於現地安裝時，建議將感測器垂直貫入土層，以 減少遲滯圈大小。

2、為加以驗證土壤導電度與溫度關係，建議增加其他種類土壤之試 驗，以驗證此公式之廣泛適用性。

3、由土壤導電度與溫度試驗結果發現在較高含水量下，其土壤導電 度受溫度影響甚大，因此未來進行非飽和現地監測時，建議增加溫度 之監測，以修正補償導電度值，進而在導電度轉換含水量時能有一較 為精確之含水量值。

4、由於遲滯現象受乾溼循環速率快慢而有所不同，因此未來進行非 飽和土壤現地監測時，建議先進行現地率定並且搭配溫度量測，若現 地監測結果遲滯現象產生則可分別就乾側及濕側進行回歸。

5、本研究之含水量與導電度關係，僅就寶二水庫粉土進行一系列試 驗，不同土壤粒俓分佈之遲滯現象可進一步探討。
