摘　　要：温室的采光性能决定着进入温室的能量和作物用于光合作用的光合有效辐射大小。但采光性能的优劣在中国缺少明确的评价指标。该文综合分析了已有研究成果,提出了太阳总辐射透过率、光合有效辐射及其在温室内分布的均匀性等3个技术参数作为温室采光性能的评价指标。Lighting performance in greenhouse is crucial for heat gain and Photosynthetically Active Radiation（PAR）density for crop photosynthesis in greenhouse.At present,China lacks a series of the harmonious and standardized indices to evaluate lighting performance in greenhouse.On the basis of analyzing current research achievements,total solar radiation transmittance,PAR,uniformity of illuminance were suggested to determine lighting performance in multi-span greenhouse.
