Abstract:
This article studied on spatial-temporal changes of forest resources in Xixia county, Henan province. By means of IMAGINE software, TM data of 2 years in Xixia county were used for analyzing. Through band combination, image stretching, supervised classification, matrix analysis and recoding, images were ready for GIS analysis and RS image drawing. The result showed that areas of broad-leaf forest and areas of coniferous forest increased from 1998 to 2002, and the increased parts changed from fields and brass lands. It also showed that variables of forests concentrated in low altitude, and in high altitude variables centralized near roads and rivers.
