The Spatial Patterns of Plant Population Distribution at the Barren Slopes in the Arid Valley along the Upper Reaches of Minjiang River

Abstract:

Through the variance/mean ratio index, the patchiness index, the Morisita index, the intensity index and the crowded mean index, the studied results present that:1) the variance/mean ratio index, the patchiness index and the Morisita index of the 17 plant populations are significantly greater than 1 suggesting a typical clumped type;2) the average of crowded mean index is between 14.4 and 488.95, of which 5 are greater than 100 occupying 29.41 %, 4 are greater than 50 occupying 23.53 %, and the intensity index of all ranges from 0.21 to 3.59, and is significantly less than 8. Of all, 11 are greater than 0 and less than 1, occupying 64.71 %. The aggregation degree of the spatial patterns is generally high and is significantly different among varied populations.
