定義了關系udbd （基於上下游關系的設計結構矩陣） ，避免了傳統dsm對活動關系描述的單一性，增強了對活動關系的描述能力;定義了迭代udbd ，解決了多種迭代模式的描述問題;定義了重疊udbd ，使利用矩陣描述活動重疊成為可能。 -
The construction of middle and small - size reservoirs is impact - profound human activities. this paper aims to conduct flood - routing of designed inflow floods of downstream reservoirs under consider ation of existence of upstream middle and small - size reservoirs, quantitatively analyze the degree of impact of the upstream reservoirs " dam - break floods or flood - regulating functions on design inflow floods of the downstream reservoirs
上游修建多個中小水庫就是一種較大規模的人類活動，本文研究旨在考慮上游多個中小水庫影響的條件下，對現有的下游水庫設計入庫洪水過程進行調洪演算，定量分析上游中小水庫的蓄泄對下游水庫設計入庫洪水過程調度的影響程度。
