1.Summarized the development of 3S(GPS, GIS, RS) technologies and their application on the forest fire prevention, and expounded the development of forest fire prevention system and the existing questions and trends of monitoring system for forest fire prevention;
The Forest fire prevention is the technology which has much relations with geographic information, so if we make use of 3S technology, we can greatly improve the levels in the area of monitoring, saving, forecast, analyze, statistic and decision so as to prevent in unfired state and discover at litter fire and save life and properties in time. Only by this way can we reduce the losses from forest fire disaster and protect the forest ecological resources and pepole's life and properties.
The forest fireproofing information system, using component GIS, has successfully realized the technology of automatic withdrawing from information around fire location, which can supply timely and exact information of forest fireproofing management, and it runs well in practical application.
Sensor networks have wide applications. Example applications include fireproofing, volcano and earthquake monitoring, environment monitoring and military target-tracking.
Both theory and observations suggest that forest fire control in fire-prone landscapes increases landscape diversity, but that it is lowered by fire control in landscapes of intermediate to low diversity.
S" techniques(Remote Sensing,Geographic Information System and Global Positioning System)has been used more and more in forest fire control in the world. MODIS is one detector of Terra's(EOS-AM1), which has been lunched on December 18,1999 by NASA Goddard Space Flight Center of US. This document has studied the possibility of different bands to detect the burning information from MODIS data by analyzing the information of related bands' data. The method to detecting fire information from the data has also b...

With the development of Communication, the application of GPS becomes a very important issue. This paper introduced the structure, functions and the implementation principles of the forest fire prevention monitor and control system based on GPS. Also some key technique was introduced in this paper such as software design of monitor system, and communication system etc. Practice showed that the system could improve the accuracy and efficiency of forest fire prevention.
