克一河林业局境内水湿地分布很广,约占全局经营总面积的10％。这些水湿地既不能天然更新,也不能进行人工造林,过去一直被列为非林地。从1975年开始,克一河林业局对水湿地进行了大规模的机械化改造。首先排水筑埂,而后在筑起的坝埂上人工栽植落叶松,一般当年成活率达90％,次年保存率不低于85％,现已栽植3万多亩。其中早期营造的落叶松,林分平均高2.5米,平均地径5厘米,已经郁闭成林。实践证明,水湿地经过排水筑埂后造林效果是好的。
Ke Yihe Forestry Bureau within the distribution of a wide range of wetlands, accounting for about 10% of the total global business area. These wetlands can neither be naturally renewed nor reforested and have historically been classified as non-forested. Since 1975, Ke Yihe Forestry Bureau has carried out large-scale mechanized transformation of water wetlands. First of all, draining water to build a dam, and then planted artificial larch on the dam, the general survival rate of 90% then, the following year preservation rate of not less than 85%, has now planted 30000 acres. One of the early build larch, stands average 2.5 meters high, with an average diameter of 5 cm, has closed forest. Practice shows that afforestation effect of water-wetland after drainage construction is good.
