Abstract
Based on five-phase remote sensing image data, RS and GIS technologies were used to quantitatively analyze the quantity, rate and structure of land use changess in Shunchang county, Fujian Province, using the relevant calculation model of land use. The results showed that the land use types were frequently converted to each other between 1995 and 2015 in Shunchang county, among which forestland and cultivated land became the land with the most increase and decrease in area, respectively. In terms of the rate of change, the single dynamic degree of forestland, water area and unused land are all positive, among which, water area has the fastest rate of change with a dynamic degree of 9.57%. Grassland, cultivated land and construction land all have negative values, and cultivated land has the fastest rate of decrease. In terms of land use structure, both land development index and reclamation index show different degrees of decreasing trend. This study can provide scientific reference for the rational planning and utilization of land in Shunchang county and the surrounding counties.
