| 2 | Spatial interpolation of orchard soil pH using soil type and planting duration as auxiliary information显示文摘Intensified field management in orcahrds has resulted in significant and widespread acidification in the soils.However,effectively mapping the spatial patterns of soil pH aiming to support ecological management is impeded by its large variotions across soil types and planting durations.Kriging methods were used to integrate soil type and planting duration information for effective mapping of orchard soil pH in a case study in orchards of the Northeast Jiaodong Peninsula,East China.A total o f 1472 surface soil samples were collected,and the planting duration o f each sampled orchard was acquired to generate a planting duration map via Voronoi tessellations.The performance of five kriging methods was compared,namely,ordinary kriging(OK),OK combined with soil type(OK_ST),OK combined with planting duration(OK_PD),cokriging combined with soil type and planting duration(OCK_STPD),and OK combined with soil type and planting duration(OK_STPD).Results showed that soil pH declined significantly with increasing planting duration and exhibited moderate spatial variability over the study area.Soil type and planting duration both had significant influence on the spatial distribution of soil pH.The OCK_STPD and OK_STPD methods showed better prediction efficiency than OK,OK_ST,or OK_PD.With regard to the predicted maps of soil pH,the OCK_STPD and OK_STPD methods highly reflected local variations associated with soil type and planting duration,but the OK method was poorly representative.Categorical soil type and planting duration information may be used as ancillary information to improve the mapping quality o f orchard soil pH.The OCK_STPD and OK_STPD methods were practical and efficient methods for interpolating orchard soil pH in the study area.The resultant high-quality soil pH maps can contribute to improved site-specific management in the orchards. | Chuancheng FU Haibo ZHANG Chen TU Lianzhen LI Xinghua LIU Yongming LUO | 2020 | Pedosphere2020，30，5： | 0 |
