Research Abstract

本研究の目的は、「統合的風食スキームのための生態系モデリング」である。研究対象地域は、東アジア内陸乾燥地のなかでも黄砂発生が積雪や植生の変動に対して敏感であるモンゴル草原とする。黄砂が頻繁に発生する春は、消雪や植物の成長など陸面状態に大きな変化がみられるが、この過程を現実的にモデリングする。モデリングにおいては、黄砂発生に関わる要因として、冬の積雪・土壌凍結、春の土壌水分・枯れ草、大規模な気象など、自然の諸過程に加えて、家畜による採食の影響も考慮する。具体的に、以下の手順で研究を進める。1.植生・土壌水分の動態と風食過程の関係を解析する。2.生態系モデルを開発し、その検証を行う。3.開発した生態系モデルと既存の大気モデルを統合的風食スキームに組み込む。
本年度は上記の3を中心に研究を進め、以下の3点の内容について実施した。当初の目的をほぼ達成した。
1.特別観測地における観測・調査の継続
・自動気象ステーションによる気象データ(気温、湿度、降水量、風向・風速)、土壌水分・温度データの取得・生態系モデルの入力パラメタ(植物種組成、バイオマス、土壌の物理性・化学性)の収集
2.統計解析の継続
・地表面状態(植被、バイオマス、土壌水分)と風成プロセスの関係
・地表面状態の持続性とそのダスト発生への影響
3.開発した生態系モデルと既存の大気モデルを統合的風食スキームに組み込む
