水庫集水區治理成效評估研究

Management Evaluation Method for Watershed of Reservoirs

摘要


水庫保育工作乃爲一長期性之治理措施,爲促進國內的水庫永續經營發展,使有限的水資源發揮最大效益,則更須深入探討與評估各項保育工作之治理成效及整治效果。現今國內水資源問題日益嚴重,加上水庫興建不易,是以水資源開發應以維持原有供水效能爲首要,然而在自然條件不佳、先天開發失當的情形下,目前部份水庫已淤積嚴重,水質污染惡化,水庫調節功能漸失,因此當務之急乃加速推動現有水庫之集水區保育工作。爲具體呈現各項保育工程之整治效果,本研究蒐集彙整歷年水庫保育之相關資料,具體評估水庫保育工作之治理成效,提供未來水庫保育計畫規劃及評估工作之參考依據。結果顯示白河水庫總體效益之治理益本比爲5.22,明德、大埔與阿公店水庫分別爲3.36、4.40及2.08,皆符合治理效益之標準,足見所投資推行之集水區保育工作乃存有實質的效益。

並列摘要


The reservoirs conservation work belongs to the long-term management practice. For developing a sustainable management of reservoirs and the best utilization of limited water resource, it is necessary to evaluate the effectiveness of the conservation work of reservoirs. This study collects and arranges the data of the watershed management program. The results would be practical and convenient in planning and evaluating the conservation of reservoirs in the future by way of establishing the information system of the integral reservoirs conservation data. Results of the present evaluation show that the overall benefit-cost ratios are 5.22 for Bai-Ho Reservoir, 3.36 for Ming-Te Reservoir, 4.40 for Ta-Pu Reservoir and 2.08 for A-Gon-Dien Reservoir. These results demonstrate that the program is economically effective.
