水生無脊椎動物分類與多樣性學科組的研究方向為淡水無脊椎動物學。重點研究重要類群的分類學和系統學、生物多樣性格局及其驅動過程、動物對人類干擾的回響以及在受損生態系統的生態功能，以及瀕危無脊椎動物的致危過程和機制。

基本簡介
(1)分類學與系統進化。運用形態學、分子生物學、個體發育等手段對無脊椎動物關鍵類群開展α、β、γ水平上的分類學和系統學研究。(2)多樣性格局及其驅動過程。在深入開展內陸水體無脊椎動物多樣性格局(如β多樣性、鑲嵌度等)的基礎上，在不同的尺度上，研究關鍵驅動機制(環境選擇、生態漂變、物種形成和個體擴散)對這些格局的影響。(3)對人類干擾的回響以及在受損生態系統的生態功能。在摸清動物的群落結構、功能和生物多樣性，及甄別驅動動物分布的關鍵環境要素的基礎上，剖析群落對人類干擾(如土地利用、全球氣候變化)的回響。在此基礎上，構建基於無脊椎動物的生態系統健康評價標準體系，為我國嚴重富營養化水體的治理提供科學和技術支撐。(4)河流無脊椎動物生態學研究。選擇我國不同地域的典型河流，系統開展無脊椎動物的生態學研究，以期實現我國河流無脊椎動物生態學研究的全面躍升。在此基礎上，探討重要河流理論在我國河流系統的普適性及特殊性，為我國流域的綜合管理與可持續發展提供科學依據。(5)瀕危無脊椎動物的致危過程和機制。
