摘 要: 该文探讨并建立了适合于中国华北平原夏玉米的作物水分胁迫指数(CW S I)模型。通过对夏玉米的冠层最小阻力、零平面位移和粗糙度进行分生育阶段取值,得到了适合于夏玉米的水分胁迫指数模型。 The theoretical model of the crop water stress index(CWSI) for monitoring summer maize water stress in North China Plain (NCP) was established in this paper. The values of the minimum canopy resistances, the zero-plane displacement and the roughness length were explored and analyzed at different development stages of summer maize.
