摘要： 利用山东省第三次荒漠化调查监测数据和聊城市1961～2005年的气候资料，对气温、降水、蒸发以及大风等气候因子的变化特征及其对荒漠化的影响进行了分析。结果表明：（1）气候因子是聊城市荒漠化的主要影响因子之一，荒漠化过程与气温和大风密切相关，与降水和蒸发的关系较为复杂；（3）春季气温的快速回升、降水显著偏少、大风以及蒸发量急剧上升造成的气候干燥对荒漠化的影响极为显著。

Abstract: By using the data of the third desertfication investficatiom and monitoring planning of Shandong province and corresponding climatic data during 1960～2005 of Liaocheng, this paper analysed climate factor’s feature and its impacts on land desertfication. The results of this study are as follow: (1) The land desertfication of Liaocheng is highly associated with the change of climatic factors. Land desertfication positively correlated with temperature and wind speed and days, and had complex relationship with the amounts of precipitation and evaporation. (2) Compared with other seasons, spring, with high temperature, low precipitation, high evaporation and strong wind, is the main factor influencing land desertfication in Liaocheng.
