摘　　要：在奉节脐橙种植区野外采集表层土壤样,探讨不同土壤类型、不同地貌类型土壤中16个有益元素分布特征。结果表明:N、P、K元素作为作物生长所必需的大量元素,在紫色土中含量最高;河谷平原土壤有益元素富集情况最好,其次是低山、台地及丘陵,中山元素富集情况相对其他地貌类型较差。Surface soil samples were collected in Fengjie navel orange cultivation area. The distribution characteristics of 16 beneficial elements in different soil types and different geomorphological types were studied. The results showed that the contents of N, P, K elements which were necessary for crop growth in purple soil reached the highest. In the valley plain soil the enrichment of beneficial elements were the best, followed by low mountains, mesas and hills. The enrichment of beneficial elements in Zhongshan was the poorest.
