標題: | 行政院國家科學委員會專題研究計畫成果報告:環境永續性評估、管理程序與方法之建立─子計畫二:環境承載力、總量管制與政策環評之研究─水資源面向 (III) | 作者: | 童慶斌 | 公開日期: | 2004 | 出版社: | 臺北市:國立臺灣大學生物環境系統工程學系暨研究所 | 摘要: | 本報告書建立水質與水量之總量管制之方式, 為在考量累積性衝 擊之影響下, 建立合理分配總量( 承載力) 之管制方法, 最後並將此 方法應用於新竹縣市的頭前溪流域作為研究案例說明。 在水量部分則是建議以系統動力模式作為主要分析的模式, 以評 估水資源的供需情況, 並藉由缺水指標作為承載力推估之依據, 其中 公共用水則是以年缺水指標( SI)為1,而農業用水則是以另一缺水指 標( ASI) 為0.8, 作為推估最大可供水量之依據, 水量之累積性衝擊 則是評估不同產業的用水需求量。本研究目前只分析水資源供應總量 與可能需求關係, 未來可藉由優化模式的權重評估不同產業可供水量 之分配。於水質總量管制評估, 則是依據公告水質標準, 藉由模式評 估考量累積性衝擊之影響, 進而結合多目標優化模式推得最佳之污染 分配量。 本研究建議將各項環境資源負荷建立於單位面積上, 以利於後續 環境管理。且由政策環評評估各區域的單位面積負荷, 作為計畫環評 之審查依據,並將SEA 與EIA 加以結合應用,使環境管理能上下一致, 減少計畫環評相同程序的重複審查。研究中依據總量管制之分析, 建 立政策環評之評估流程, 並根據現有的政策環評矩陣, 建議修正以環 境承載力與累積性衝擊影響因子作為評估項目。 The major task of this report is to establish the method of the total mass control of water quality and quantity. The total mass control method is to allocate the total mass (carrying capacity) based on considering the cumulative impact. The Tochen creek watershed is used as a case study. In the aspect of the water quantity, a system dynamic model is developed to assess the capacity of water supply. Shortage Index (SI) with the value of 1 and agricultural shortage index (ASI) with the value of 0.8 are used as standards to determine the capacity of water supply for public and agriculture, respectively. Then, cumulated water demands are estimated from different users to test whether water supply is sufficient. This study currently only evaluates the relationships between potential water supply and possible water demand. In future, an optimization model will be developed to determine the best allocation of water supply. In the aspect of the water quality, the cumulative impact and optimal allocation of allowable pollutant discharges are included in developing total mass control method. The cumulative impact is simulated by QUAL2e model and the optimal allocation of allowable pollutant discharges is determined by a multiobjective optimal model. This research suggests that environmental resources and assimilation capacity can be allocated to land and expressed as unit area load for future environmental management. Besides, strategic environmental assessment (SEA) is applied to evaluate the impacts of police, program, or plan on unit area load, while project environmental impact assessment (EIA) is applied to assess whether a developing project violates the standard of unit area load. Thus, SEA and EIA are linked together by using unit area load. The study also analyzes the process of SEA and modifies the evaluation matrix of SEA by considering factors to influence carrying capacity and cumulative impacts. |
