2017年,MTP项目与内蒙古通辽市科尔沁左翼后旗林业局合作,在1个沙荒地进行了生态修复,造林树种包括樟子松、五角枫、柳树、黄菠萝、小叶锦鸡儿等,其中主体造林以樟子松为主,道路防风带以五角枫等为主,内部沙化区域栽植了部分小叶锦鸡儿。其中,穿插了部分柳树、黄菠萝等。

In 2017, cooperating with the Forestry Bureau in Keerqinzuoyihou Qi, Tongliao, MTP contributed to the ecological restoration in one sandy land by planting a mix of Pinus sylvestris L. var. mongolica Litv. (scotch pines), Acer mono (maples), willows, phellodendron amurens and caragana microphylla Lam. The main species is scotch pine. Maple trees were planted as the windbreak. While caragana were planted in some part of the desertified areas. Among them, a few willows and p. amurenses spread out over the plot.

从图1看,樟子松和柳树始终保持着缓慢增长,五角枫的平均树高持续下降。其中五角枫由于保存率的下降导致平均树高的下降,同时存活的五角枫中出现了一部分根部存活,主干死亡的情况,也导致了平均高度的下降。

As shown in the image 1, scotch pines and willows keep growing slowly, however, maple is under a continuing decline, which is resulted from the decline of maples’ survival rate, and in additional, we also found some maples death in trunks, but their roots were alive, which causes the decline of average height.

在雨季的走访中发现(图2、图3),樟子松的生长相对均衡,没有出现成片死亡的情况。植被恢复情况较快,完全覆盖了地表,植被的高度没有覆盖樟子松,树行相对清晰。

During our visit in rain season, we found that the growth of scotch pines is generally even, the situation of mass death does not occur. Besides, image 2 and 3 show that the ground vegetation is recovering in a fast pace, almost covering the ground, yet not high enough to block the growth of scotch pines, the rows of pines can still be clearly identified.

在测量过程中,我们针对林地苗木的死亡、伤害等信息进行了编码记录。经统计,存在问题的苗木占比46%。

During the measurement, we recorded the death and damage information of the trees. Statistically, problem seedlings account for 46% of all trees.

五角枫出现较多的主干死亡,基部枝条重新萌发的情况。

The situation of trunk death but re-germination in basal shoots occurs to many maples.
