鄱阳湖流域1：25万分级流域边界数据集（2002年）

该数据集为鄱阳湖流域2002年1:25万所属一级流域、二级流域、三级流域矢量边界数据集。在全国1:25万一级、二级、三级流域的基础上，提取鄱阳湖流域范围内的流域数据，包含了流域名称及流域代码等指标信息。
数据集包含3个矢量数据，“鄱阳湖流域一级.shp”，“鄱阳湖流域-二级.shp”，“鄱阳湖流域三级.shp”。

This dataset is the 1:250,000 vector boundary dataset of the first-level, second-level, and third-level basins within the Poyang Lake Basin in 2002. Based on the national 1:250,000 first-level, second-level, and third-level basins, the basin data within the Poyang Lake Basin were extracted, which includes indicator information such as basin names and basin codes.

The dataset contains three vector data files: "Poyang Lake Basin First-level.shp", "Poyang Lake Basin-Second-level.shp", and "Poyang Lake Basin Third-level.shp".
