MODIS(MCD43A4)中国2000-2023年燃烧面积指数数据集
收藏资源简介:
1.本摘要简明扼要地介绍了基于MODIS(MCD43A4)数据生产的中国2000-2023年燃烧面积指数数据集。数据集的生产主要依赖于准同步的MODIS地表反射率数据,通过结合动态阈值法、主动火点信息以及区域生长算法等多种方法,对像元尺度的燃烧痕迹进行识别和提取,最终生成年度燃烧面积产品。 2.高校、研究所、企事业单位等科研单位。 3.该数据集对于量化中国区域长时间序列的火灾活动规律、评估火灾对生态系统(如碳循环、植被恢复)的影响、以及支持相关领域的政策制定和灾害管理具有重要的潜在利用价值与科学意义。
1. This abstract briefly introduces the burned area index dataset of China from 2000 to 2023 generated based on MODIS (MCD43A4) data. The dataset is produced mainly using quasi-synchronous MODIS surface reflectance data, and identifies and extracts burn scars at the pixel scale by integrating multiple methods including dynamic threshold method, active fire point information and region growing algorithm, finally generating the annual burned area product. 2. Applicable scientific research institutions include universities, research institutes, enterprises and public institutions. 3. This dataset holds significant potential utilization value and scientific significance for quantifying the long-term time series fire activity patterns across China, assessing the impacts of fires on ecosystems (e.g., carbon cycle and vegetation restoration), and supporting policy formulation and disaster management in relevant fields.
