| Abstract: | experimental and 50 sprouts analysis tree plots from the I-72,I-69,I-63,mingle clone poplar afforested within Dongting Lake areas and outside its beach were collected without considering the strain.By of using H=M(1-Le -KA )as curvilinear equation of height of tree,basic standard year is 6 years,exponential spur is 2m,exponential series is 7(10-22m).By use of the method of height of tree relative value,the height of tree value at every exponential spur and every year were derived.Site index form which is suitable for 3 clones of south China poplar,and mixed clones afforestation poplar stand was set up. |
