| Abstract: | Investigation on growth condition and reasonal density of locust forest in semi-arid area of east Gansu Province was conducted. In the light of soil dynamic hydraulics and the moisture nutrient area for growth of trees in different stages, according to moisture dynamic equlibrium equation of forest soil, the paper calculated the initial planting density of young forest and reasonal density of aged forest for management. |
