Land utilization situation in Heilongjiang Province based on quantitative geography model

The purpose of the report is to expose the land quantity, distribution regularity, structure arrangement, the quantity and quality of unused land in Heilongjiang Province. Based on the changes on the cadastre and the image 1∶100000 scales of Heilongjiang Province in 2003, the land utilization structure in 13 cities of Heilongjiang was analyzed by applying the GIS technology and some others quantitative geography models. The evaluation results are as following: the rich varieties of the agricultural land resources in Heilongjiang Province are suitable for scale management; human jamming intensity is not great high, and neither is the land utilization extent; the function of land utilization system is not desirable, hence a further development should be constructed; the quality of unused land resources is inferior.
