Identification of fragmented cropland in arid and semiarid sandy areas: a case study of horqin left rear banner

The sustainable development and utilization of sandy areas in arid semiarid regions is strategic importance to ensure both food ecological security. unique geographical environment these uncontrolled exploitation by farmers lead large amounts fragmented cropland. Despite government management, the quantity distribution croplands unknown, accurate identification region’s can provide data support use areas. We propose a method for identifying cropland based on scale transformation. Small-scale approximately represented at larger scales, so we apply small-scale high-resolution remote sensing images identify features obtain information scale, i.e., ratio area. By correcting identified from low-resolution using them as basis resulting calculation, more be 1 scale. In this study, was applied with 0.54 30 m resolutions that were acquired during same period, Horqin Zuoyihou Banner study results showed (1) there 13,637.08 hm 2 due precipitation terrain topography, mainly central western 2) sample point plot positively correlated area consistent distribution. Therefore, efficient achieved through
