摘要

在台灣已有許多學者使用AGNPS各種不同版本從事相關研究，美國農業部近年來配合電腦系統更新，不斷改良AGNPS，研發出適用於視窗版的Ann AGNPS。Ann AGNPS配合ArcView GIS擴張模組，可直接於兩者結合介面中進行DOS的功能，包括轉檔、屬性分析、繪出水流圖、去除集水區邊界、集水區出口、圖形套疊及分割子集水區和估算網格逕流率、氮磷傳輸量和泥砂生產量等。本研究以台南縣左鎮鄉一開發治理後之小農業集水區為研究試區，藉以比較Ann AGNPS與AGNPS DOS功能之差異。若將來建立台灣完整之土壤、田野與氣候資料圖層，則Ann AGNPS必能應用於台灣地區。

There have been many scholars in Taiwan using several different versions of AGNPS for relative studies. United States Department of Agriculture has continuously improved AGNPS for the update of operation system in computer, and therefore Ann AGNPS used in Window system is made up. In the combined interface for Ann AGNPS and expanded modules of ArcView GIS, we could process AGNPS DOS version directly. The interface includes converting to grid, neighborhood statistics, drawing stream, delineating watershed and outlets, overlaying figures, clipping subwatershed, and calculating runoff rate, delivery of nitrogen, phosphorus, and sediment yield. A small well-treated agricultural watershed in Tso-chen, Tainan County was selected as material for this study to compare the difference between Ann AGNPS and AGNPS DOS. If we could set up the complete shape file about soil, fields and climate station in Taiwan, then Ann AGNPS may be applied in Taiwan.
