| According to the regulation of the second time national rangeland resources survey by remote sensing, the latest data of rangeland resources of Xinbaerhuyou Banner is obtained by applying TM images as the information source. Man-computer interactive interpretation method is used during the course of interpreting remote sensing images. To interpret correctly, the interpreting keys of grassland types on TM images is established through analyzing images and relative references, then these interpreting keys is corrected in the fields. The edition of graphical data is operated on MGE software and the area of all kinds of grassland types is calculated on the TITAN GIS software. The result shows that: The total rangeland area of Xinbaerhuyou Banner is 2257078.62 hm2, its area percentage is 89.86%; the area percentages of temperate steppe type, temperate meadow steppe type, lowland meadow type, marsh type and temperate forage improved grassland are separately 85.11%, 1.23%, 12.19%, 1.19% and 0.28%. In lowland meadow type, two new subtypes-lowland meadow subtype and lowland saline meadow subtype are found, which were not found in the former materials. The data can be used as basic data for later dynamic detection. It can also provide theoretical basis for the sustainable use, protection and management of rangeland resources of Xinbaerhuyou Banner.
