摘要

近年來由於台灣污染問題日益嚴重，且傳統的養殖魚塭沒有較完善的給排水系統，漁民為了取得量足且質優的養殖用水，只好自設閘門及抽水設施取水，導致地層下陷；且因給排水共用同一水路，造成了魚病互相傳染等問題，為了解決這些問題，規劃設置養殖區完整的公共設施是必要的。
本文為了公平、合理地分配42養殖區之建設順序，將42養殖區之給排水模式依面積大小、取水方式、輸水方式及配水方式予以分類，並根據農業工程研究中心對42養殖區做規劃後之總工程費，配合漁業署90年度養殖魚塭田間調查成果、42養殖區之平均存活率與收成時單尾重及84~89年主要養殖魚種之平均單價等資料，以益本比法對各養殖區做經濟分析，估算出年計成本、年計效益及益本比。優選時為了同時考慮經濟效益與地區均衡發展，以益本比經濟分析方法，分別對台灣全區及各縣市排序，其結果可供優先建設或考慮之參考。

Recently, the pollution problem in Taiwan is more and more serious and the transitional pools did not have more perfect water supply and drainage system. Fishers were in order to take enough and good aquaculture water, so they sat gate and the facilities of pumping to get water by themselves. It resulted in layer depression. Because they used the same canal for water supply and drainage, it caused the problem of fish diseases infection to each other. In order to solve these problems, it is needed to plan and build complete public facilities in aquaculture district. This study is in order to allocate the building sequence of 42 aquaculture districts fairly and reasonably. Classifying 42 aquaculture districts by area, and taking water method, and water carrier method, and water supply method. According to the data from the total engineering cost of planning 42 aquaculture districts based on the report of Agricultural Engineering Research Center together with the results of field investigation collected by Fisheries Administration Council of Agriculture in 2001, and the average survival rate and one fish weight when harvesting and average unit price of main fingerling in 1995~2000 of 42 aquaculture districts, the economical benefit of 42 aquaculture districts is analyzed by cost-benefit ratio method to estimate annual cost, annual benefit, and cost-benefit ratio. In order to consider both economical benefit and developing balance in every county when we are optimizating. Base on the results of cost-benefit ratio analysis, we can sort all districts in Taiwan and in every county in sequence. The result can be given priority to the future reference on construction or consideration.
