中國是世界上人口最多的國家，保障中國糧食安全對中國乃至世界經濟發展和社會穩定都是至關重要的。近年來，伴隨中國工業化進程，糧食生產賴于保障的水土資源持續向非農部門轉移，引起了世界各國對中國能否保障糧食安全的大討論。原有的對糧食安全的研究常常是農業部門的不考慮水資源的平衡關系，而水利部門又沒有根據糧食需求、糧食貿易等其它經濟環境條件來分析水資源平衡關系。 -
On the basis of the monitoring results of land subsidence and calculation of deep groundwater resources by using water balance method, it is shown that the leakage recharge from its upper shallow groundwater account for approximately 38. 2 %, drainage of the clay layers, about 41. 3 %, water release from the aquifers, around 5. 6 % and lateral inflow, some 14. 9 %, of the total groundwater resources
摘要根據天津平原地面沉降監測結果，採用水量均衡法，計算出深層地下水開采量中，淺層地下水越流補給量佔38 . 2 % ，粘土性壓密釋水量佔41 . 3 % ，彈性釋水量佔5 . 6 % ，側向流入量佔14 . 9 % 。
