For the implementation of the strategy of our country food security, easing the contradiction between human and land in Guizhou referring to a large number of relevant literature, combining with the Guizhou Province of the international situation, from the input intensity, utilization degree, production efficiency and the continuous condition of four aspects, with 14 indicators to jointly build the cultivated land intensive level evaluation system of Guizhou Province, using objective weights for each indicator given mean square error method, the spatial and temporal variations of cultivated land intensive level in Guizhou were analyzed, and the GWR model was used to analyze the factors affecting the level of intensive cultivated land of Guizhou Province. The results show that:(1)the intensive utilization of cultivated land in Guizhou Province from 2003 to 2018 showed the overall upward trend;(2)at the intensive utilization level of cultivated land in all cities(states)of Guizhou Province, the intensive utilization level of cultivated land in Guiyang City was the only one to decline gradually, while that of Anshun City, Liupanshui City, Qiandongnan Prefecture and Zunyi City was developing steadily, and that the rest of the areas had some fluctuations;(3)through the analysis of GWR model, it was found that the most important factors affecting the intensive utilization level of cultivated land in various cities(states)of Guizhou Province were the input intensity and sustainable status; the difference in utilization degree was small in regions, while the difference in output efficiency was large in regions. The results of this study can provide scientific reference for enhancing the intensive cultivated land use level in Guizhou Province.
