全国县域玉米产量估测数据集（2020-2021年）

基于县域的全国玉米估产数据集（2020-2021年）是由福州大学数字中国研究院发布的一个数据集，该数据集主要涉及全国范围内玉米的估产数据。
该数据集包括了2020-2021年全国玉米县域范围内的估产数据。其中，数据来源主要是统计数据。通过对这些数据进行处理，可以获得全国范围内玉米的总产和单产数据，这些数据可以用于研究玉米的生长状况、分析其时空分布规律等。
同时，该数据集还可以通过地图等方式直观展示全国玉米的时空分布情况。通过这些地图，研究者可以更加深入地了解玉米的生长状况，从而为农业生产和粮食安全提供有益的支持。

The county-level nationwide maize yield estimation dataset (2020-2021) was released by the Institute of Digital China, Fuzhou University. This dataset primarily focuses on maize yield estimation data across the entire country.

This dataset contains county-level maize yield estimation data across China for the years 2020 and 2021. The data sources are mainly statistical records. After processing these data, total yield and per-unit yield (yield per unit area) of maize nationwide can be obtained, which can be used to study maize growth conditions, analyze spatiotemporal distribution patterns, and other related research topics.

In addition, this dataset can visually present the spatiotemporal distribution of maize across the country through maps and other means. With these maps, researchers can gain a deeper understanding of maize growth conditions, thereby providing valuable support for agricultural production and food security.
