2019年中国国家重点预防区水土流失状况

本数据集为国家级重点预防保护区2019年水土流失面积（动态监测区域）数据，包含土壤侵蚀强度，并按照侵蚀强度分为轻度、中度、强烈、极强烈、剧烈，主要包括国家级重点预防保护区，包括大兴安岭、呼伦贝尔、长白山、滦河、黑河绿洲、塔里木河绿洲、子午岭、六盘山、三江源、金沙江上游、岷江上游、桐柏山大别山、新安江、东江上游区域统计各侵蚀强度的面积以及各侵蚀强度面积占土壤侵蚀面积的比例以及国家级重点治理区水土流失状况（动态监测区域），并按照侵蚀强度分为轻度、中度、强烈、极强烈、剧烈，主要包括东北黑土地治理区、西辽河大凌河中上游治理区、永定河治理区、太行山治理区、河龙区间多沙粗沙治理区、泾河北洛河上游治理区、祖丽河渭河上游治理区、湟水洮河中下游治理区、伊洛河三门峡库区等区域统计各侵蚀强度的面积以及各侵蚀强度面积占土壤侵蚀面积的比例。本数据来源于中华人民共和国水利部的2019年中国水土保持公报，通过手动录入获取。

This dataset contains 2019 soil erosion area data (dynamic monitoring areas) for national key prevention and protection zones, with soil erosion intensity categorized into five levels: slight, moderate, intense, extremely intense, and severe. For the national key prevention and protection zones including the Greater Khingan Range, Hulunbuir, Changbai Mountains, Luan River, Heihe Oasis, Tarim River Oasis, Ziwuling Mountains, Liupan Mountains, Sanjiangyuan, Upper Jinsha River, Upper Minjiang River, Tongbai-Dabie Mountains, Xin'an River, and Upper Dongjiang River, the area of each erosion intensity level and the proportion of each intensity's area to the total soil erosion area have been statistically calculated. This dataset also covers the soil erosion status (dynamic monitoring areas) of national key soil erosion control zones, with the same five erosion intensity classifications. The covered control zones include: Northeast Black Soil Region Control Area, Upper and Middle Reaches of West Liao River and Daling River Control Area, Yongding River Control Area, Taihang Mountains Control Area, Multi-sand and Coarse-sand Control Area in the Hekou-Longmen Section of the Yellow River, Upper Reaches of Jing River and North Luo River Control Area, Upper Reaches of Zuoli River and Wei River Control Area, Middle and Lower Reaches of Huangshui River and Taohe River Control Area, and Yiluo River and Sanmenxia Reservoir Area. For each of these control regions, the area of each erosion intensity level and the proportion of each intensity's area to the total soil erosion area have been statistically calculated. This dataset is sourced from the 2019 China Soil and Water Conservation Bulletin issued by the Ministry of Water Resources of the People's Republic of China, and the data was obtained via manual entry.
