2018年,MTP项目与内蒙古通辽市科尔沁左翼后旗林业局合作,在3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 2018, cooperating with the Forestry Bureau in Keerqinzuoyihou Qi, Tongliao, MTP contributed to the ecological restoration in three plots of 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.

经调查核算,项目共造林3635亩,199925棵,2020年度总体保存率为80.75%,相较于前两年发生了一定程度的下降。该林地立地条件较差,地势起伏较多,存在部分完全裸露的沙荒地,内部存在少量耕地,相关的抚育质量较高,密度几乎没有发生变化。

According to the investigation, the total afforestation of the project is 242.3 hectares, 199925 trees, and the overall survival rate in 2020 was 80.75%, which experienced a certain decreasing compared with the previous two years. The condition of the plot is poor, the terrain is quite rugged, there exists some completely exposed desert, and a small amount of cultivated land inside, trees were highly maintained here, the density almost remained the same.

三块林地三年的保存率对比如下图,可以看出2018-3林地的保存率的变化不大,保持着较高的水平。

Comparison of the three years' survival rate of three plots is shown in the figure below, it can be seen that the survival rate of 2018-3 plot did not change much and remained at a high level.

2018林地处于初植期,松树的根系没有完全伸展,苗木相对脆弱,对环境的抗逆性较差,容易发生死亡。林地保存率依旧处于一个相对不稳定的时期,需要进行补植等措施保证林地整体的保存情况。 与2019年度的情况类似,苗木继续生长;同时,树高值分布相对均匀,没有极端化。林地中生长进入稳定状态的比例也在增加。三块林地的整体生长相对良性。

In 2018, the plot was in the initial planting stage, the root system of pine trees was not fully extended,and the fragile seedlings had poor resistance to the environment, so they are prone to death. The survival rate of the plot was still unstable, so it was necessary to take supplementary planting and other measures to ensure the overall survival of the plot. Seedlings continued to grow, as they were in 2019. At the same time, the tree height was well-distributed without polarization. More and more seedlings entered a stable growing state. The overall growth of three plots was proper.

松树的树行相对完整,没有大量缺损的情况,松树生长点也相对茂盛,没有出现明显的区域性死亡,在航拍中能够清晰地辨别出松树树行。内部的植被高度相对较矮,暂时没有影响到松树的生长。林地整体生长发育的很健康。

The rows of pine trees were relatively complete without too much defects, and the meristem regions of pine trees were flourishing, without obvious regional death. The rows of pine trees could be clearly identified in aerial photograph. The height of the plants inside was relatively low, which did not affect the growth of pine trees for now. The whole plot was growing and developing healthily.
