Paper Title:
A Study on the Relationship between Crown Characteristics, Fractal Dimension and Water Consumption of Poplars
  Abstract

The relationships among crown characteristics, crown fractal dimensions and water consumption were studied in seven 5-year-old poplar clones that were selected from the nursery garden of the Gaomi Forestry Bureau in China. The closest positive correlation was between single tree leaf area (TLA) and water consumption followed by the tree crown area (TCA). The leaf area index (LAI) and crown layer density (CLD) were positively correlated with water consumption but were not significantly correlated. There was a negative correlation between the crown shape ratio (CSR) of the L35, NL895 and I-107 poplars and water consumption. The CSR of the other clones was positively correlated with water consumption. But neither the positive nor negative correlations of CSR with water consumptions were significant. The crown characteristics of the fractal dimension had a similar variation trend. The fractal dimension had a significant positive correlation with TLA, LAI and CLD but no significant correlation with CSR and TCA. The fractal dimension of TCA (FDa) and the fractal dimension of crown volume (FDv) had a significant positive correlation with water consumption, and FDa was more closely correlated with water consumption than FDv. More fractal dimension resulted in more water consumption. Correlation analysis indicated that the presence of more foliage distributed in the crown surface or the more evenly distributed foliage in the inner crown resulted in more water consumption with the same leaf area.
