Abstract: The agricultural climatic condition is suitable for summer maize in the piedmont plain and for cotton in the Heilonggang Region in the South Hebei Area. Water resources in the area are deficient. Groundwater overexploitation is serious, the modulus of which is 8 01×10 4m 3/(km 2·a) for shallow aquifers and is 2 58×10 4m 3/(km 2·a) for deep aquifers. The comprehensive marginal revenue of water resources use in the area is highest (26 68 yuan/ton) for Langfang City and is lowest (14 85 yuan/ton) for Baoding City, the rate of which is 1 80. There are frequent environmental geological disasters such as depression cone of groundwater, in which the cone area was 5 4 thousand km 2 for shallow aquifers and was 15 9 thousand km 2 for deep aquifers in 1998, and land subsidence and obvious pollution of surviving pesticide and over-use chemical fertilizer to groundwater and grain and vegetables in the area. The water-lacking rate will be 36 2% in the area in 2010, in which the ratio between the water-transferring from the Changjiang River and the Huanghe River and the water supply will be 23 9%. The water-saving rate of 17 2% compared with the level in 1999 can be achieved by implementing the water-saving measures such as water-saving by irrigation projects (raising the comprehensive water-saving rate of 3 2%), water-suiting plant (reducing the sown area proportion of 7% for winter wheat), water stress treatment (decreasing once irrigation).
