1. Introduction
With the further development of economic construction and the transformation of macroscopic land
administration requirement, Xi’an Bureau of State Land Supervision needs to obtain the macroscopic changeinformation of new increased construction land as quickly as possible to offer target range for supervised
points. Therefore, on the basis of using high resolution remote sensing images to supervise the situation of the
newly increased construction land in some key zones, it’s necessary to use wide covered and relatively cheap
middle resolution remote sensing images to supervise the macro situation of the new increased construction
land in the whole range. In this way, it could further complete the dynamic remote sensing supervision system
of new construction land increase in flatland zones of northwestern five provinces, meanwhile, the macro
supervision and micro supervision could compensate each other to offer just-in-time and comprehensive data
for macro decision making and land supervision administration in five provinces of the northwest[1-6].
Hence, it’s necessary to conduct an experiment about the change detection of new increased construction
land with the middle resolution remote sensing images in some flat zones. Then, based on the experiment
results, the paper analyzes and discusses the ability of middle resolution remote sensing images in supervising
and discovering the change of newly increased construction land, in order to offer experience and reference to
the further work of change detection for newly increased construction land, especially for which is changed
from plow land
