摘　　要：探讨并建立了适合于镇江丘陵地区温室葡萄水分状况监测的作物水分胁迫指数(CWSI)模型。通过田间实验和观测,得到了适合温室葡萄的CWSI经验模型中的经验关系。初步的检验和分析表明,这一模型是合理的,可以用于温室内葡萄基于冠层温度信息的水分状况监测。The crop water stress index（CWSI） model for greenhouse grape water stress in Zhenjiang hilly area was set up in this paper. Through experiments and precise scientific observation, test results showed that the non - water - stress - baselines for greenhouse grape were proved to be credible. Primary analysis and validation showed that the model was reasonable, and it could be applied to monitor summer grape in green house water stress.
