Abstract:

The new concept monopolized circle was put forward to plant pattern, three theorems relating with monopolized circle was proved and then uniform index was put forward, the theoretical distribution and testing method of pattern type was derived. The forest tree's positions were measured with high precision instruments and the patterns were tested with new uniform index. The new uniform index is easy to calculate, intuitionistic to understand and rational, which is actually used to control the forest tree's pattern in forest thinning.

Key words: pattern, pattern testing, uniform index, monopolized circle, thinning
