中国玉米物候变化数据集（1981-2010）

中国玉米物候变化数据集（1981-2010）是在中国玉米种植区内114个农气站1981-2010年的长序列物候观测数据，利用趋势分析和和积温计算方法，量化分析了玉米8个连续物候期的时空分异特征和相应的生长阶段长度变化规律基础上研发的数据。该数据集包括（1）中国不同种植区玉米生育期内气候因子变化趋势数据；（2）1981-2010年中国不同种植区玉米物候期/生长阶段长度变化趋势；（3）1981-2010年历年不同种植类型的玉米3个生长阶段长度及其标准偏差；（4）1981-2010年中国玉米物候期变化趋势的空间分布数据；（5）1981-2010年中国玉米生育期内气候因子变化趋势的空间分布数据。数据集存储为.shp和.xlsx格式，由17个数据文件组成，数据量为143 KB（压缩为1个文件，36.3 KB）。该数据集的分析研究成果发表在《地理学报》杂志2018年第73卷第5期。China Maize Phenology Change Dataset (1981-2010) was developed using long-term phenological observation data collected from 114 agro-meteorological stations across China's maize-growing areas between 1981 and 2010, following a quantitative analysis of the spatial-temporal differentiation characteristics of eight consecutive maize phenological phases and the variation patterns of corresponding growth stage lengths via trend analysis and accumulated temperature calculation methods. The dataset includes: (1) data on the variation trends of climatic factors during the maize growing period in different planting regions of China; (2) variation trends of maize phenological phases/growth stage lengths in different planting regions of China during 1981-2010; (3) lengths of three maize growth stages and their standard deviations for different planting types across each year during 1981-2010; (4) spatial distribution data of the variation trends of maize phenological phases in China during 1981-2010; (5) spatial distribution data of the variation trends of climatic factors during the maize growing period in China during 1981-2010. The dataset is stored in .shp and .xlsx formats, consisting of 17 data files with a total size of 143 KB (compressed to 36.3 KB as a single file). The analytical research outcomes based on this dataset were published in *Acta Geographica Sinica*, Volume 73, Issue 5, 2018.
