| Abstract: | The relationships between blomass and plant size characteristics were studiedon four shrubs,which were Salsola laricifolia,sympegma regelii,Asterothamnus centrali-asi-aticum and Reaumuria soongorica. Reqression equations were worked out as following:Salsola laricifolia:Y=-53.2626+2.355X_1+0.9062X_2+0.5606X_3 Sympegma regelii:Y=-17.8228=0.9269X_1+0.3965X_2+1. 0531X_3 Asterotamnus centrali-asiaticus:Y=-17.2356+0.7339X_1+0.4068X_2+0.7034X_3 Reaumuria soongorica: Y=-21.3605+1.1093X_1+0.2182X_2+0.3893X_3 The Y,X_1,X_2,and X_3 in equation were in dividual biomass,diametre,vertical diameterand bushes height ,respectively.The multiple correlation coefficients of were 0.9609,0.9481,0.9150,0.9661 respective-ly. |
