長期以來，我國政府在解決水資源短缺問題上一直採用供給管理的策略，其對策主要以工程技術為主，如開發地下水、南水北調等。從目前我國缺水地區的情況來看，這種技術策略已受到了水資源儲備的約束，人們不得不把目光轉向需求管理。 -
95 % of water - used by agriculture come from groundwater, and it occupied 80 % of total water consumption ( 2001 ). water shortage is becoming the major obstacle of sustainable agricultural development and the key is raise efficiency of wateruse. the results of wofost model simulation showed that the yield of winter wheat was 2323 kg / hm2 under the rainfeed conditions, 5946kg / hm2 with irrigation, while the potential yield is 8485kg / hm2 with the abundance supply of light, temperature, water and fertilizer
（ 2 ）順義區農業用水的95來自地下水，農業用水占總用水量的80左右（ 2001年） ，水資源緊缺成為限制農業生產的主要瓶頸，在日趨緊缺的水資源壓力下，提高水分使用效率成為土地可持續利用的關鍵。採用wofost模型對順義區冬小麥的生產潛力及雨養條件下水分限制產量進行了模擬，結果表明：在光、溫、水、肥條件均滿足時生產潛力為8485kg hm ~ 2 ，雨養條件下水分限制產量只有2323kg hm ~ 2 。 -
