摘　　要：山东省全区地形地貌与气候条件差异很大,由地形地貌与气候条件构成的自然特征对灌溉农业分区的制约首当其冲。论文首先分析了山东省的地形地貌,以各种地形面积百分比作为相应指标值;并通过对比分析选择以"积温计算法"表达的干燥度作为山东省气候条件的指标值;最后,通过分析山东省的地形地貌及2000-20005年各地市的干燥度,对不同地区发展节水灌溉进行了讨论。相关指标值的确定,为灌溉农业分区和实施适宜的节水技术提供了理论支持。Because of great difference in topography and climate conditions between districts in Shandong Province,the physical condition featured by topography and climatic conditions restricts the dividing area of agricultural irrigation.This paper analyzes topographical conditions in Shandong Province and takes the percentage of every kind of terrain as the corresponding index.Then,through an analysis and contrast,the aridity calculated by method of accumulated temperature is choosen as the index of climatic conditions in Shandong Province.At last,the development of water-saving irrigation in different districts is discussed based on analyzing the topographical conditions and the aridity between 2000 and 2005 in every district in Shandong Province.Confirmation of these relative indexes provides academic support for the dividing area of agricultural irrigation and for choosing suitable water-saving technology.
