农业现代化是乡村发展的引擎，而贵州地貌以山地和丘陵为主，利于现代农业发展的平坝区少，研究坝子现代农业功能分布可以为贵州农业产业结构调整提供科学参考。利用ArcGIS10.2对2016年高清遥感影像进行解译，识别贵州省现代农业功能地块与现代农业功能坝子，利用核密度、双变量局域空间自相关分别分析地块、坝子个数空间分布特征、地块与坝子的局域空间自相关关系。结果表明： $①$ 遵义市、黔南州和毕节市现代农业功能地块面积与个数均位于全省前三，且地块与坝子区域空间自相关关系最为强烈； $②$ 坝子在遵义市播州区与红花岗区交汇处形成一个高密度核心区，地块在惠水县、长顺县、平坝区与花溪区交汇处形成一个高密度核心区; $③$ 地块面积与坝子面积呈强正相关关系； $④$ 地块占所在坝子比例为0~10%。

Agricultural modernization is the engine of rural development. Guizhou's landforms are mainly mountainous and hilly areas and there are few basins that are conducive to the development of modern agriculture. Therefore, the study of the modern agricultural function distribution of basins can provide scientific reference for the adjustment of Guizhou's agricultural industrial structure. This research used ArcGIS 10.2 to interpret the high-definition remote sensing images from 2016 to identify modern agricultural functional plots and modern agricultural functional basins in Guizhou Province, and used kernel density and bivariate local spatial autocorrelation to analyze the spatial distribution characteristics of the plots and basins, and the local spatial autocorrelation between the plots and the basins. The results show that: i. The area and number of modern agricultural functional plots in Zunyi Municipality, Qian Nan Buyi and Miao Autonomous Prefecture, and Bijie Municipality are all within the first three columns in the whole province, and the spatial autocorrelation between plot and basin area is the strongest; ii. The basins form a high-density core area at the intersection of Bozhou District and Honghuagang District in Zunyi Municipality. The plots form a high-density core area at the intersection of Huishui County, Changshun County, Pingba District and Huaxi District; iii. There is a strong positive correlation between the area of the plots and the area of the basins; iv. The proportion of the plot in the basin is mainly between 0 and 10%.
