Comparative Study on Methods of Estimating Forest Land Area

Forestland area is an important basis for determining cases involving forest fires, illegal occupation of forestland, change of forestland use and the punishment of perpetrators. Application conditions of several commonlyused methods calculating forest area were analyzed with methods of the investigation and interviewand simulating crime scene based on the practical experience. Moreover, differentiation between the results computed by different methods and computational efficiency of different methods were compared. Finally, the methods calculating forestland area were determined based on particular situation of different cases′ crime scene, measurement accuracy and work efficiency and admitted by judiciary authorities.
