摘要

Abstract >Soil depth reflects the quantity and ecosystem service functions of soil resources. However, there is no universal standard to measure soil depth at present, and digital soil mapping approaches for predicting soil depth at the regional scale remain immature. Using observation of soil profile morphology, we compared the soil depth nomenclatures from the World Reference Base for Soil Resources, Chinese Soil Taxonomy, and Soil Taxonomy. For this study, shallow soils were defined as those with an effective soil depth 100 cm. Based on legacy data and field soil survey, the spatial distribution of shallow soils in Xinjiang, China, and the main controlling environmental factors were explored. Results showed that shallow soils in Xinjiang are mainly distributed in high altitude regions such as the Tian Mountains. At the regional scale, significant correlations were observed between soil depth and climate factors, as well as between soil depth and vegetation fractional coverage. Contrary to previous conclusions at small spatial scales, terrain attributes could not explain soil depth variation at the regional scale. This study addressed knowledge gaps on soil depth prediction at regional scales while elucidating climate‐vegetation‐soil coevolution. </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs"

>土壤深度反映土壤资源的数量和生态系统服务功能。然而，目前没有通用标准来测量土壤深度，以及用于预测区域规模的土壤深度的数字土壤映射方法保持不成熟。利用土壤型材形态观察，我们将土壤深度命名与土壤资源，中国土壤分类学和土壤分类学相比。对于该研究，浅土被定义为具有有效土壤深度的薄片。 100厘米。基于传统数据和现场土壤调查，探讨了新疆浅层土壤的空间分布，探讨了中国和主要控制环境因素。结果表明，新疆的浅层主要分布在田山等高海拔地区。在区域规模中，在土壤深度和气候因素之间观察到显着的相关性，以及土壤深度和植被分数覆盖。与小空间尺度的先前结论相反，地形属性无法解释区域规模的土壤深度变化。本研究解决了区域鳞片土壤深度预测的知识差距，同时阐明了气候 - 植被 - 土壤共存。</ p>
