Growth of Robinia pseudoaeacio in different density onslope in loess area in west of Shanxi province

SUN Zhong-feng,ZHANG Xue-pei,ZHU Jin-zhao (College of Soil and Water Conservation,Beijing Forestry University,Beijing 100083,China)  
Observation and analysis were conducted on stand of Robinia pseudoaeacio of different density on slope in Loess Area in the west of Shanxi Province.Biomass of trees and planting density were closely related.Biomass of trees increased as the density increased when the density was less 2000 plants per hectare.Biomass of trees deceased rapidly when the density was greater than 2000 plants per hectare.of Highest biomass was found in 2000 plants per hectare.Significant correlations were found among breast diameter,height,crown size,biomass,branches and leaves.Logistic equation can well simulate the curve of growth of Robinia pseudoaeacio.The optimum use of Robinia psedoaeacio trees should be finished before 20 years.
