To this area precipitation materials for many years, evaporate materials, surface flow materials, hydrometeorological materials, hydrogeological materials carry on exhaustive analysis, have analysed the state of water resource of the sand district, proceed from the heat of the earth ' s surface is balanced, water yield balanced basic theories, combine the amount of regional water resource set up of the materials, such as scene, hydrology, soil of the sand district, etc. and estimate models, have calculated the surface water, groundwater of this area, has carried on models to examine according to the real data, and has predicted to the state of water resource under different climate change scenes of future that analyse. have put forward the scheme that the water resource in this area utilized rationally, use the non - linear motive force model to predict the precipitation, utilize the materials of actual observation, the natural supply amount of calculating out groundwater of sand ground of balanced principle of the amount of water used at the same time, and can exploiting amount predict to groundwater, district of sand,
本文以寧夏半乾旱地區鹽池縣沙地水資源為研究對象，對該地區多年降水資料、蒸發資料、徑流資料、水文氣象資料、水文地質資料進行了詳盡的分析，分析了沙區的水資源狀況，從地表熱量平衡、水量平衡的基本理論出發，結合沙區的氣象、水文、土壤等資料建立了區域水資源量估算模型，計算了該地區的地表水、地下水，根據實際資料進行了模型檢驗，並對未來不同氣候變化情景下的水資源狀況進行了預測分析，提出了該地區水資源合理利用的方案，運用非線性動力模型對降水量進行預測，同時利用實際觀測資料，運用水量平衡原理計算出沙地地下水的天然補給量，並對沙區地下水可開采量進行預測。 -

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 。
