Identification of Driving Factors in Cultivated-Use Change Based on GIS and RS

摘要

It of important practical significance for protecting cultivated land to master the driving factor and its spatial variation of cultivated-use change accurately. By using of "3S" technology, applied Pearson correlation analysis and logistic regression model to identify the main driving factors of cultivated-use change. The results show: cultivated use change was determined by natural factors and human factors together, but natural factor was the leading. Cultivated loss was mainly turn to grassland, construction land, and waters; the main driving factors were soil texture, geomorphic type, organic, slope. Cultivated gain was mainly from forest land and unused land, soil types, elevation, sand percentage in soil, and population density were the driving factors.
