The farmland use intensity is an important focus in the course of the household behavior study,which can help understand the man-land relationship in rural areas.The paper adopts the factor analysis,gravity center analysis and spatial autocorrelation analysis,and uses softwares such as SPSS,ArcGIS and GeoDa software,to explore the spatial distribution and its change features of the farmland use intensity based on the county-level administrative unit in Henan Province.The farmland use intensity analysis based on the 126 county-scale data finds the following results.(1) The county-scale units at higher level of the farmland use intensity are mostly located in the northeast of Henan Province.County-scale units located in the places closer to the city are also at higher level of the farmland use intensity.County-scale units which are at the similar level of the farmland use intensity have the trend of spatial concentration.(2) The gravity center of the farmland use intensity is located in the northeast of the geometric center of Henan Province,and it continues to move to the northeast over time.(3) The level of the farmland use intensity is the result of the households' choice of investment structure under the restriction of natural geographical condition,economic environment,political system environment,social and cultural environment,combined with their own conditions.(4) The fact that the paper explored the features and changes of spatial distribution of the farmland use intensity can help us understand the statuses of household production decision in different areas and conditions.Finally,the paper suggests that agricultural production regionalization should fully consider the different levels of farmland use intensity in different areas,and upgrade each region's comparative advantage in the course of developing agricultural economy.
