内容記述 著者らが前に開発した数値データ中心のサトウキビの生産支援情報システム(Sun et al., 1998a)をより効果的なものにするために,GIS(Geographic Information System:地理情報システム)ベースのシステムに拡張した.本報では,南大東島に設置した約100筆の定点サンプリング圃場に関する点情報のマッピングとそれを利用した解析結果について報告した.品質データ(単位収量,糖度)などを点表示あるいはサーフェイス表示し,空間的な分布特性の一部を解析した.糖度および単位収量は年度格差がかなり大きいことを示し,その主要因は気象であると推察した.また,糖度については北区の沿岸部などに継続的に低い地域があることがわかった.蔗汁の元素成分のうちK濃度やP濃度と糖度とを数値地図上で比較し,それらの関係の一部を明らかにした.南大東島の圃場は全体的に酸性土壌であるが,基盤整備事業完了区にはpH8程度の値を示す圃場があり,土壌改良の効果を確認できた.このように限られた点情報のマッピングであっても地域的な生産構造の把握には効果的であり,生産システムの改善に利用できることを示した.
