Abstract:This paper studied the growth, stand productivity, ecological effects of nine-years-old Black Locust and their limiting factors in Wangzhuan coal waste pile. The results showed that the tree height, diameter at breast height (DBH) and timber volume had different growth rhythm: tree height had the earliest fast-growing period, which was in the first year (growth rate is 1.65m per year), the fast-growing period of DBH was in the second and fourth years (growth rate is 0.6~1.0cm per year); the fast-growing per...
