摘要

本研究目的旨在建立適用於我國之糧食生產評估系統，同時以水稻生產為例進行產量模擬與驗證。整合氣象、作物及土壤等資料庫利用DSSAT模式進行水稻產量模擬，並建立模式驗證機制以確認系統具有評估能力。模擬結果則以地理資訊系統進行面化，依據5 km × 5 km網格估算值，評估不同農業政策調整下整體水稻生產力，提供氣候變遷因應措施及農田活化等政策之依據。

The purpose of this study was to setup an evaluation system for grain crop production in Taiwan. Take paddy rice production as an example, the system adopted DSSAT model and used weather, crops and soil databases for model simulation. The simulated outputs were used to evaluate the entire regional paddy rice productivity based on a 5 km × 5 km coordinate system with the aid of geography information system (GIS). The verification system to validate simulation outputs was also established. By using the evaluation system with various environmental conditions, it would provide valuable information for strategy planning to cope with climate change as well as to activate the reuse of fallow land.
