ABSTRACT: 
The project was one of the most important projects of PRC Land And Resources Ministry in 2001. Land-using Trends 
RS Watching was significant components of PRC Land And Resources Ministry new overall investigating of land and 
resources. The implementation of this project was very important to strengthen land management, to ensure dynamic 
state balance and occupying compensating balance of cultivated land total amount in Shandong province. 
The project applied the software of PCI version 8.1 to rectify, to match, to inlay and to fuse with multi-sources and 
multi-timeliness remote sensing data to SPOT, TM and ETM satellites data, promoted spatial resolution of surface 
features and distinguishing capability of spectrum. The project applied three kinds of ways to pick up change 
land-using information, discovered change land-using information in maximal extent. The project fixed position of 
change map-speck spatial data precisely, determined the smallest map-speck area of different of satellites data, 
accomplished integration of RS and GPS, promoted accuracy and reliability of watching results, obtained integrated 
watching achievement of vector data, grid data and attribute data, by wild investigation, verification and GPS site 
surveying. 
1. INTRODUCTION 2. TECHNIQUE ROUTE 
The implementation of land-using trends Remote 2.1 Monitoring Time Interval 
Sensing Watching was very important to strengthen 
land resources management, to ensure dynamic state Monitoring duration was divided into October 1998 
balance and occupying compensating balance of to October 2000 and October 2000 to October 2001 
cultivated land total amount in Shandong province. two time interval. 
By monitoring could find out the change of 
land-using in time and accurate, comprehended the 2.2 Monitoring Object 
change trends, arrangement and scale of land-using, 
grasping the use situation of construction land and Monitoring object included the situation of small 
cultivated land, offered foundation information at towns construction and development; the situation of 
present for city construction, gave serve to land city scale expanding and land-using overall program 
enforcing law checking, the investigation, program, execution; the condition of fundamental farmland 
and management, protection and use reasonable of protection; the main monitoring object which using 
land and resources, supplied effective land resources RS watching results checked land modification 
safeguard for national economy construction and investigation was the change of construction land and 
society development. cultivated land.
