The definition is the foundation of the assessment of intensive use of cultivated lands.The study developed an indicator system for cultivated land intensive use in Heilongjiang Province.With calculations of entropy and composite index and support of GIS

this study analyzed the spatial difference in intensive usage of the cultivated land.The result shows that

the intensive use level of the cultivated lands displayed obvious regional differentiation characteristics

influenced by the natural conditions of the regions.The cultivated lands in the middle and south parts of the study area had the highest intensive degree

those in the east and west were lower

and those in the north were the lowest.In terms of the weights of the indicators

the investment intensity was most important factor in evaluating intensive use of cultivated land.The farming infrastructure investments in the study area were substantially lower than the production investment.The findings of the project provide the basis for policy making and adjustment of farming investment in the area.
