Abstract:

Prime farmland (PF) is high-quality farmland and prime farmland protection area (PFPA) is a region designated for PFs special protection. However, rapid urbanization in China has led to a tremendous farmland loss. Based on RS and GIS technique, we proposed a semiautomatic method for designating PFPAs from high-resolution satellite imagery (HRSI), which involved object-based image analysis, farmland composite evaluation, and spatial analysis. HRSIs can provide elaborate land-use information, and the PFPA demarcation showed strong correlation with farmland area and patch distance. For spatial planning and convenient management, different demarcation rules should be applied for suburban and exurban areas around a metropolis. Finally, the overall accuracy of HRSI classification was about 80% for the study area, and high-quality farmlands from evaluation results were selected as PFs. About 95% of the PFs were demarcated within the PFPAs. The results of this study will be useful for the scientific planning and automatic designation of PFPAs.
