Abstract: Driving force mechanism is thought a core direction of land use change research, and the matching method research of human factor data and land use units is regarded as one of important work bases for discussing human factors to drive land use change. Based on the immanent connection between human activities and land use units, and assisted by population resident density and land economic output value density, the matching methods of population, gross output value and land use units were detailedly expatiated. Using the data of land use, population and gross output value in 1999, the matching methods were applied in Fengtai district, and spatial differentiations of population resident density and land economic output value density of Fengtai district were analyzed. Some results are obtained.(1) The area of residential land use is 16118hm~2, with 53.16% of total land area in Fengtai district in 1999. The spatial differentiation of its population resident density is very prominent, the highest 35995 persons and the lowest 1260 persons in a hectare.(2) The land use area with economic output is 23435.26hm~2, with 77.29% of total land area in Tengtai district in 1999. The spatial differentiation of its land economic output value density mainly showed between non-agricultural land and agricultural land, and the density of the highest urban and town land is as 45 times as that of food cultivated land.(3) The matching method expatiated will be an effective tool and can be used to solve the link problem of human and nature factors. Further, it will promote the progress of geographic integrated research.
