| Abstract: | The effects of slope position on growth and nutrient status were investigated in the artificial wind-breaking and sand-fixing forest of Hedysarum Laeve(6 a) in semi-mobile dune of Horqin sandy land by comparing with natural abandoned land(the department with 50 m adjaceut in same slope).Results showed that:slope affacted the growth status significantly.The height,numbers,canopy density,coverage density,survival rate in downhill were higher than those in uphill and midslope,and ground diameter in upslope was... |
