黑龙江省1：25万主要农作物种植面积数据集（1980年）

种植结构的演变与农作物品种的改变、气候变迁、土壤水质环境以及种植习惯等因素密切相关。本数据主要包括黑龙江省1980年主要农作物种植结构的空间变化。作物播种面积数据主要来源于多年累积的统计数据，与黑龙江省1:25万县域区划数据进行关联，以期为东北地区农业种植结构的变化研究以及相应对策的制定提供数据支撑。

The evolution of agricultural planting structures is closely correlated with a variety of factors, including changes in crop varieties, climate change, soil and water environmental conditions, and local planting practices. This dataset mainly covers the spatial changes in the planting structures of major crops in Heilongjiang Province in 1980. The data on crop sown areas are primarily sourced from long-term accumulated statistical records, and have been linked to the 1:250,000 county-level administrative division data of Heilongjiang Province. This dataset aims to provide data support for research on changes in agricultural planting structures in Northeast China and the formulation of corresponding countermeasures.
