Dear Jari,
 
Thank you for replying my question. 
 

I could take the ordinate of the respective plots according to your advices.
 
However, I could not take the ordinate of the respective arrows, which derived from environmental conditions. 
 
I try to analyze the influence of environmental conditions on the environmental organisms by $B!H(Bdistance-based redundancy analysis (db-RDA)$B!I(B. Thus, I use the function $B!H(Bcapscale$B!I(B, which is in the package $B!H(Bvegan$B!I(B. In this analysis, I could show an ordination figure based on db-RDA. In order to reconstruct the db-RDA figure in windows $B!H(Bexcel$B!I(B, I also try to get the ordinate of the respective plots, which shows respective organisms, and the ordinate of tip of the respective arrows, which derived from environmental conditions. According to your advices, I could take the ordinate of the respective plots in the figure, as the $B!H(Bvalues$B!I(B. 
 
Would you mind teaching me how to get the ordinate of tip of the respective arrows, which derived from environmental conditions?
 
 
Yours sincerely
