Abstract: In the study of large-scale landscape, adopting low resolution remote sensing data often causes the trouble of modifiable area unit, while scaling-u p technique can hardly assure the reliability of the conclusion. Landscape stati stics and its sampling technique, in which the basic principles and methods of s tatistics were applied to landscape ecology, would be a good way for solving the problems mentioned above, being available to the more accurate research on larg e-scale landscape with limited input. In this paper, some basic concepts of lan dscape statistics were introduced, and the principles and methods of landscape s ampling and statistical inference were discussed. The application scope, difficu lties, and development prospects in using landscape statistics were also approached.
