"Yichang Orange" enjoys a long reputation, and Yaqueling area is one of its typical producing areas. In this paper, the geochemical survey of vertical profile of rock-soil was carried out in the center of orange production of Yaqueling area, Yichang City. Through the analysis of nutritive elements and rare earth elements, the migration characteristics of related elements from rock to soil were investigated, and the suitability of orange production was evaluated. The results show that most of the soil elements will inherit their content level in the parent rock, as shown by such phenomena as the similar REE distribution pattern and the similar degree of relative enrichment or dilution of Si, Na, K, Ca, Mg, Mo, Sr and other elements. According to correlation analysis and cluster analysis, three groups of elements of positive correlation such as Al-Fe-Ge-Ni-B-K-Si, S-N-Se-P and Cu-Zn-Mo were identified. The sequence of the suitability of the soil forming parent rock for planting orange soil is feldspathic quartz sandstone of Honghuatao Formation, calcareous sandstone of Pailoukou Formation, marl of Duodaoshi Formation, and calcareous conglomerate of Luojingtan Formation. In addition, some suggestions for planting optimization are put forward.
