摘要
利用山东省2000-2005年期间各地市的农业需水量和用水量,计算出山东省各地的平均缺水程度指标;并根据山东省目前4种主要的灌区类型确定其相应的灌区指标;最后,根据山东省现有资料计算并分析各地市现状用水水平指标值。各相关指标值均很低,表明山东农业用水形势严峻,需要结合各地市自身情况,因地制宜发展高效节水灌溉技术,同时指标的确定也为合理利用农业水资源提供了科学依据。
Using the data of agricultural water demand and crop water consumption from every region in Shandong province during the years 2000-2005, calculated the indicators of water shortage degree in every region; and then determined each region irrigation corresponding indicators in accordance with the current four major types of irrigation area; finally, get the indicators of status of water usage level around Shandong Province. The lower value of these relevant indicators show that the water situation is grim around Shandong agriculture and it is needs to develop high efficient water-saving irrigation technologies in line with local conditions. At the same time, the identification indicators got in this paper provides a scientific basis for the rational usage of agricultural water consumption.
