成都平原耕地重金属浓度空间分布数据集
收藏资源简介:
本数据集为“成都平原耕地重金属浓度空间分布数据集”,基于Sentinel-2遥感影像、气候、地形、土壤母质数据及地面调查样本,采用机器学习算法构建。数据空间分辨率为100米,时间覆盖2023年,描述了成都平原耕地三种主要重金属元素(砷As、汞Hg、铅Pb)的浓度空间分布情况,可为区域农业生态环境监测、土地利用管理及土壤重金属风险评估提供科学支撑。数据以TIF格式存储,可通过项目平台共享与下载使用。
This dataset is the "Spatial Distribution Dataset of Heavy Metal Concentrations in Cultivated Land of Chengdu Plain". It was constructed using machine learning algorithms based on Sentinel-2 remote sensing imagery, climate, topography, soil parent material datasets and ground survey samples. With a spatial resolution of 100 meters and covering the year 2023, the dataset describes the spatial distribution of concentrations of three major heavy metal elements (arsenic As, mercury Hg, lead Pb) in the cultivated land of the Chengdu Plain. It can provide scientific support for regional agricultural ecological environment monitoring, land use management and soil heavy metal risk assessment. The data is stored in TIF format and can be shared and downloaded via the project platform.
