Abstract: As a national-level poverty-stricken county, the Shangyi County, conducts agricultural production and ecological environment planning through suitable local circumstances in order to shake off poverty fundamentally. At the same time, the Hebei Geology and Mineral Bureau contributed capital to carry out a survey of agriculture eco-geological environment. The result of the survey demonstrated that: in potato superiority area, the element content of Si, K, Na was relatively higher, and the one of Mg, Cl, B, Ca, Cu, As was relatively lower, which reflected the eolian sand environment. The quality of irrigation water was better, and the water was abundant in Sr and presents alkalescence. Creating site geological environment model and summarizing recommendations in potato planning, could improve the plowland capacity effectively and develop the soil inner quality advantage. At the same time, it had conductive meaning for soil balanced fertilization. The result of area planning provides reference for revision on land utilization planning and crop planting structural adjustment.
