| 摘 要： | 调查研究结果表明，实验所采取的各项措施是可行有效的，沼泽地生境发生了明显变化，地下水平均下降０．６－１．０ｍ，地温５－２０ｃｍ处提高６－８℃，土壤的理化性质得到明显改善，水、气、热趋于协调。林木生长良好，６年生落叶松树高、胸径生长量分别为０．４６ｍ和０．５０ｃｍ，已达到速生丰产林标准。

| Abstract: | 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. |
