黑龙江省1：200万土壤全氮分布数据集(1992年)

本数据集包括黑龙江省管辖的76个市县地区的土壤全氮含量空间分布数据。将纸制图件扫描后，处理，数字化, 采用该图土壤分类系统，根据该图图斑注记，分析处理、制图输出。从而为从事土壤学及农业生态学等研究的学生和科研人员提供数据支撑。

This dataset contains spatially distributed data of total soil nitrogen content across 76 cities and counties under the jurisdiction of Heilongjiang Province. Paper cartographic sheets were scanned, processed and digitized. Using the soil classification system specified in the original map, we conducted analysis and processing based on the annotations of its map patches, and generated the final mapped output. This dataset provides data support for students and researchers engaged in studies including soil science and agricultural ecology.
