中文摘要：

以县域为基本单元，在以地貌形态把河南省各县域分为平原县、丘陵县和山区县的基础上，以经济密度为指标，借助数理统计和空间分析相结合的方法对各地貌类型区内和地貌类型区间的经济密度区域差异水平及演化态势进行分析，并对河南县域经济密度的空间格局及演化特征进行讨论．河南省县域经济密度在不断提升的过程中区域差异也不断拉大，地貌类型区内县市间经济密度差异突出，对总体差异的贡献较大，地貌类型区间的差异相对较弱且呈不断缓解的趋势．县域经济密度呈现出以郑州为中心的由中部丘陵向东部平原和西部山地降低的态势，中心城市邻近县市的经济密度相对较高．

英文摘要：

Taking county as a study unit, all counties hilly countries and mountainous countries according are divided into three classifications which are plain counties, to landform shape in Henan province. Using mathematical statistical analysis and spatial analysis methods, taking economic density as a variable indicator to measure regional economic development, the level and the evolution trend of disparity of country level economic density are analyzed inside and outside the landform area, the spatial pattern and evolution characteristics of county level economic density are also discussed. Results showed that with the growth of regional economic density in Henan, regional differences of economic density among counties are also growing, especially in the landform areas and that contributes great to total disparity; the differences among Landform areas are relatively weak and present a decreasing tendency. In spatial perspective, a depressed trend of economic density has been presented from the middle hilly counties around Zhengzhou to the eastern plains and western mountainous areas, the economic density of the counties that near the central cities is relatively higher, which are possibly caused by location condition, industrial scale, industrial structure and land investment in different counties and so on.
