资源简介：
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1970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 structure is closely correlated with multiple factors including changes in crop varieties, climate change, soil and water quality conditions, and traditional planting practices. This dataset primarily covers the spatial variations in the planting structure of major crops in Heilongjiang Province in 1970. The crop sown area data is mainly derived from accumulated multi-year statistical records, and has been associated with the 1:250,000 county-level administrative division data of Heilongjiang Province. This dataset is intended to provide data support for research on changes in agricultural planting structures in Northeast China and the formulation of relevant countermeasures.
