黑龙江省1：200万土壤pH分布数据集(1990年)

本数据集包括黑龙江省管辖的76个市县地区的土壤pH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 comprises spatial distribution data of soil pH across 76 counties and cities under the jurisdiction of Heilongjiang Province. Initially, paper-based cartographic documents were scanned, preprocessed and digitized. Subsequently, adhering to the soil classification system defined in the original map and utilizing the annotations on its map patches, we carried out analytical processing and generated the final cartographic output. This dataset provides data support for students and researchers engaged in studies of pedology, agroecology and other related fields.
