高原春青稞株成穗数与气象条件关系

运用统计学原理与计算方法系统分析研究西藏自治区山南地区多年气候因子对青梨株成穗数的影响规律，建立了株成穗数-气候模型。试验结果表明，青梨三叶-分蘖期降水偏多有利于株成穗数的增加；分蘖-拔节期气温高、降水少，对增加株成穗数极为不利，拔节-抽穗期水热条件配合的好坏，直接影响株成穗数的大小，近35年分蘖-拔节期平均气温呈上升趋势，降水呈减少趋势，气候变暖，变干均不利于青稞株成穗数的增加。     

拉萨地区油菜白锈病发生发展的农业气象条件分析

对拉萨１９８８－１９９０年油菜白锈病和同期的气象要素进行了相关分析，６－７月平均气温高，夜间温度大，日较差小，阴雨寡照和空气湿度大，有利于白锈病的发生发展；提高地表温度，可减轻白锈病的发生发展。     

西藏地区夏季旱灾的防御对策研究

The monthly rainfall data of May to August of 14 stations in Tibet from 1961 to 1998 are used. By using the index of drought/flood from reference document, the climatic character of early summer and midsummer drought are discussed. The results show that the frequency of early summer drought is higher than that of flood in Tibet and the drought occurs every 2～3 years on the average. The frequency of midsummer flood is higher than drought along the Yalung River and in mid-western Naqu, the slight-drought occure every 5～7 years and heavy-drought every 6 years. Otherwise, the chance of midsummer drought is more than flood in southeastern and northeastern Tibet, the drought occurs every 2 years. In the last 40 years, there were more drought during 1980s, but few early summer drought during 1990s and midsummer drought in 1960s. The concept in the rule of drought are made clear, the defensive strategies against the summer drought and different defensive measures are put forward with the aim at high output, fine quality and high efficiency in the production and the sustainable development of agriculture.
