摘要

本文為檢討水土保持技術規範第95條中有關總量管制的規定，並以假設案不同流入滯洪設施之集水分區面積比例的流出量與滯洪量進行檢算，得知不論流入或未流入滯洪設施的集水分區而其是否有開發利用情形，其總流出量與滯洪總量體均相同，且可有效的調控在總量管制的概念中。惟未流入滯洪設施之集水面積接近70%時，可能會使得滯洪設施幾乎達到零排放情形，此部份可提供開發案件規劃設計者參考。

This study is to review the provisions of total amount control in Article 95 of the Technical Code for Soil and Water Conservation, and check the outflow and detention based on the proportion of the catchment area that flows into the flood detention facility in different hypothetical cases, and it is known that regardless of the inflow or non-inflow of detention The catchment area of the facility and whether it is under development and utilization, its total outflow is the same as the total amount of flood detention, and can be effectively controlled in the concept of total amount control. However, when the catchment area that has not flowed into the flood detention facility is close to 70%, the outflow is rarely almost zero discharge. This part can be used as a reference for development plan designers.
