Abstract

Abstract: Choosing representative greenbelts in Jiamusi City, Heilongjiang Province as the objectives, this paper studied the effects of different greenbelt structures on the air negative ions concentration. The results indicated that air negative ions concentration differed significantly with greenbelt structure. Multilayer structure tree-shrub-grass had the highest air negative ions concentration and the best air quality, followed by tree-grass, shrub-grass, and grass.

Key words: Larix chinensis, Fractal dimension, Spatial distribution pattern, Pattern intensity, Pattern scale
