The results of investigation and study showed that various measures adopted in the experi ment were feasible and effective. It Wasobvious that the change of swampland habitat The average level of subterranean water failed 0. 6~1.0m,the ground temprature increased 6~8C at the place of 5-20cm above the horizon,the physicochemical properties of the soil were obviously improved, water,air and heat tended to coordination,the growth of forest-tree was very splendidly. The tree height and the growth of breast-height diameter of the 6 annual larch were 0. 46m and 0. 50cm, and it had reached the criterion of fast-growing and high-yielding plantations.
