To get some knowledge about t he relationship between soil biological prop erties and t hickressgrowt h of bamboo ,23 plot s wit h different productivity were selected for investigating eyehigh diameter (D . E. H. ) and analyzing soil samples. D . E. ( ) ( ) ( ) H. has a close relationship wit h t he number of soil bacteria X ,actinomyces X ,fungi X ,activities of hydrogen p er 1 2 3 oxidase ( X ) , urease ( X ) ,protease ( X ) , and p hosp hatase ( X ) , wit h correlation coefficient s at 0 . 94 1 , 0 . 432 , 4 5 6 7 0 . 682 ,0 . 75 1 ,0 . 768 ,0 . 899 and 0 . 9 14 ,resp ectively . Sucrase activity (X8 ) is not well related to D . E. H. The mulitiple liner regression equation is : y = 2 . 3064 + 8. 8954 ×10 - 7 X 1 + 1. 8356 ×10 - 7 X 2 + 6. 8422 ×10 - 6 X 3 - 0. 6099 X 4 - 1. 10 1X 5 + 6. 225 X 6 + 0. 05088 X 7 + 0. 057 1X 8 . The multiple correlation coefficient ( R = 0 . 96) reached significent level ( a = 0 . 00 1) . For fractional correlation coefficient s ,only b
