Effective control of land spatial development intensity can guarantee resource intensive use and ecological environment protection. This paper, based on Heibei's 148 county domain units, uses EDA, GIS and OLS model with geographic weighted regress model to analyze land development intensity factors, and to study its mechanism. A notable positive spatial self-correlation exist in county domain with convergence. LISA local self-correlation shows "point-zone-area" structure in the whole province. GDP per capita, population density, land cial expense, net debits of financial units and slope coefficient have positive influence on land development intensity, but land fixed asset investment, land industrial GDP above designated size, permanent general farmland area and distance to Bo Sea are negative. These factors vary in influence and sensitivity with regions. Geographic locality the first key factor directly influencing land development intensity, which is also driven by economical and social development level, and financial supports. Increment of construction land intensive use can slow down the fast rise of land development intensity. Agricultural protection controls effectively the direction and intensity. This study offers reference for Hebei in variably managing and controlling land development intensity and optimizing land spatial development pattern. 
