Focus on the problem of big differences in computing aspect factor of subcompartment between two methods of most eigenvalue based on DEM and scalar quantity,a new vector method for the aspect factor of subcompartment is proposed in terms of the characteristics of digital terrain analysis and the theory of vector statistics.

Selection and analysis of auxiliary factors using sampling method of sub-compartment

With the each stand factors from the sub-compartment by forestry management investigation,the factors of C.

This paper suggests that sub-compartment data be used as the core data when an overall design is made for developing such databases as forest resources, forest fire control, forest management, biodiversity conservation, etc.

Interactive relation in classroom teaching as an important factor which exerts effect on teaching efficiency reflects the sociological phenomenon in education, and however, teaching in small class provides favorable conditions for interaction in classroom teaching.

In contrast to the big class, small class teaching has more advantages of time and space.

Small-sized class teaching, as a branch in small classes education, has now become a new area of expertised research, and resulting in a number of researches.
