摘要: Hollow village is a widespread phenomenon all over China nowadays. Finding out the potential utilizable land in rural region and promote the land circulation is of great significance to holding the arable land above the red line of 1.8 billion mu in China. In this study, the image characteristics of circulating land in the study area was analyzed firstly. Then the homestead and wasteland were extracted using object-oriented remote sensing information extraction technology, which include multi-scale image segmentation and establishment of extraction rules based on ENVI. After that the purpose, function and features of extracting system of rural circulating land by remote sensing were explained and the development approach of integration of remote sensing and GIS was discussed. The ENVI/IDL secondary development library platform combined with secondary development tools ArcGIS Engine was adopted. Extracting circulating land by remote sensing images, spatial analysis and mapping functions were realized in this system, using COM technology for multi-language and multi-platform hybrid programming.
