本文分析了１９８０年以来北京农村发展及农村用水变化趋势与特点。由于官厅、密云两大水库供不量和工业退水减少，以及农业节水等原因，农村总供水量呈下降趋势。随着农村经济的发展和广泛采取农业节水措施，农村用水的结构比例发生变化，农作物灌溉用水量逐渐减少，而果林、渔业、人畜、工副业等用水量逐渐增加。文章又根据２０００年农村发展的主要指标，预测了未来农村的需水量。
This article analyzes the trends and characteristics of rural development and rural water use in Beijing since 1980. Due to the lack of Guanting and Miyun reservoirs and the reduction of industrial backwater, as well as agricultural water saving and other reasons, the total rural water supply is on a downward trend. With the development of the rural economy and the widespread adoption of agricultural water saving measures, the proportion of rural water use structure has changed. The amount of water used for irrigation of crops has been gradually reduced, while the water consumption of fruit trees, fisheries, livestock and poultry, and sideline occupations has gradually increased. Based on the main indicators of rural development in 2000, the article predicts the demand of water in rural areas in the future.
