摘　　要：在深层坑渗灌为基础的大田试验条件下,研究了极端干旱气候区成龄葡萄果浆成熟期不同水分处理条件下冠层温度的变化规律。主要得到如下结论:从气象学理论的角度阐明了冠层温度与大气温度之间的关系,分析了不同水分处理下冠层温度和大气温差日变化过程的原因;建立了以能量守恒定律为基础的冠层温度模拟模型;大气温度与冠层温度的变化趋势基本一致,二者存在很好的线性关系;建立了以灌溉定额为参数的冠层温度与大气温度的拟合模型并进行了分析;确定了吐鲁番鄯善地区葡萄果浆成熟期最优灌水量为160.428 m3亩-1。Under the condition of field experiment based on deep pit infiltrating irrigation,the canopy temperature＇s changing pattern of mature grape under different water treatment in the extremely arid area was researched.The results were as follows： The relationship between canopy temperature and atmospheric temperature was illustrated from the perspective of meteorology,the reason of the variation of canopy temperature and atmospheric temperature in one day under different water treatment was analyzed.A simulating model of canopy temperature was founded based on energy conservation pattern.The trend of atmospheric temperature was basically identical with canopy temperature,with a good linear relationship.A fitting model of canopy temperature and atmospheric temperature with the parameter of irrigation amount was founded and analyzed.The optimum irrigation amount of mature grape was 160.428 m3 mu-1 in Shan Shan of turpan.
