Indian Soil Erodibility Dataset (ISED)

Soil erosion has been spotted as one of the major global problems, and soil erodibility is the property of soil which refers to the erosive nature of the soil. India is also struggling with the erosion problem in most parts of the country. A national-scale soil erosion study is needed to assess such types of problems. ISED (Indian Soil Erodibility Dataset) is a step toward building datasets in mapping soil erosion at a national scale after IRED (Indian Rainfall Erosivity Dataset). This dataset consists of K-factor (t-ha-h/ha/MJ/mm), soil erodibility indices like CR (Clay Ratio), Modified Clay Ratio (MCR), and CLOM (Critical Level of Organic Matter) map over India at high resolution (250 m). Distribution maps of soil erodibility corresponding to the districts and soil types of India are also added to this dataset. This dataset is an additional dataset at a national scale for soil erosion modeling which will be handy data for experts and researchers.

土壤侵蚀已被认定为全球主要环境问题之一，土壤可蚀性（soil erodibility）是表征土壤抗侵蚀特性的固有属性。印度国内多数区域亦饱受土壤侵蚀问题的困扰，亟需开展全国尺度的土壤侵蚀研究以评估此类问题。印度土壤可蚀性数据集（Indian Soil Erodibility Dataset，简称ISED）是继印度降雨侵蚀力数据集（Indian Rainfall Erosivity Dataset，简称IRED）之后，面向全国尺度土壤侵蚀制图构建的相关数据集之一。该数据集包含分辨率为250米的高精度印度全国范围K因子（单位：t·ha·h/ha/MJ·mm）、黏粒比率（Clay Ratio，CR）、修正黏粒比率（Modified Clay Ratio，MCR）以及有机质临界值（Critical Level of Organic Matter，CLOM）等土壤可蚀性指标的空间分布图件。此外，数据集还纳入了匹配印度各行政区与土壤类型的土壤可蚀性分布地图。本数据集为全国尺度土壤侵蚀建模提供了补充数据，可为相关领域专家与科研人员提供实用的数据支撑。
