A Classification and Comparison of Competition Indices

Guan Yuxiu Zhang Shougong(Forest Resources College, BFU) (Chinese Academy of Forestry)  
The perfect and imperfect categories are presented as a new classification of competition indices on individual trees, based on whether the subject and competitive trees and their spatial distributions (which are the main aspects contributing to competition) , are involved in the indices estimation. Indices of the perfect category can be used in stand dynamic simulating, but imperfect ones behave well only in the case where the predicting stand remains untouched.Criteria with five items, which are used to judge the quality of indices, are offered considering that the indices should be theoretically reasonable and practical, and the important items of the five stresses that the indices are sensitive to competition status and measurable or predictable of individuals whenever they are encountered.
