研究方向1:全球变化及其它多重环境压力对淡水湖泊生态系统的影响
气候变化(如气候变暖、极端气候)将成为本世纪影响生物多样性和生态系统功能的主要因素之一。与此同时,其他环境压力(如富营养化、农业化学品污染)可能会与气候变化产生复杂的交互作用。本研究组利用中宇宙温度控制实验系统,该系统已经加入世界水生态中宇宙系统联盟(http://mesocosm.org/mesocosm/wuhan-warming-mesocosm-facility-wwmf/)。研究内容:①全球气候变化与多重环境压力是如何共同影响生态系统中各生物类群结构;②气候变化与多重环境压力是如何共同影响水域食物网结构特征,包括能量流动路径及食物网稳定性等;③气候变化与多重环境压力是如何共同影响水域食物网碳、氮、磷等的元素循环特征。
