2019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，林地东侧为高速公路，北侧为高速公路辅路，造林树种包括樟子松、五角枫、小叶锦鸡儿等，其中主体造林以樟子松为主，间种少量五角枫，沙化严重的区域栽植小叶锦鸡儿。
Cooperating with the Forestry Bureau in Keerqinzuoyihou Qi, Tongliao in 2019, MTP contributed to the ecological restoration of one sandy land plot by planting a mix of Pinus sylvestris L. var. mongolica Litv. (scotch pines), Acer mono (maples) and Caragana microphylla Lam. The main species is scotch pine, with few maples in-between. And caraganas were mostly planted in severe desertified area.

2019年林地立地条件较差，林地两面沿路，所以相对来说，其栽植和抚育的难度较低。2025年度抽样测量显示，其整体保存率均值为63%。林地整体没有发生较大变化，保存率始终在60%左右浮动，林地保存状况相对稳定。具体保存率变化见下图：
The forest plot was surrounded by the roads on two sides, which makes it easier to plant and nurture the trees. According to the 2025 forest survey, the overall survival rate in 2025 was 63%. The forest has not changed significantly, the survival rate has always fluctuated around 60%, and the surivival situation of the forest is relatively stable. The changes in survival rates are shown below:

樟子松生长的情况相对健康，树高、胸径、地径等指标均有一定程度的上升，其增幅较往年比较显著，说明林地苗木在增粗增高。2025年度树高增幅达36%，表明林地已进入快速生长期。树高分布呈显著单峰形态（峰值位于3.6米处），林木高度集中于均值附近，表明林分整体生长健康。树高数值范围为1–6米，离散程度适中。
The growth of pines was relatively healthy, tree height, diameter at breast height (DBH), basal diameter and other indicators has risen to a certain extent. Tree height increased by 36% by 2025. These data are more significant than previous years, indicating that the seedlings are thickening and increasing, and gradually entering the rapid growth period. The tree height distribution shows a distinct unimodal pattern (peaking at 3.6 m), with heights concentrated around the average, indicating healthy overall stand development. The tree heights range from 1 to 6 m, with a moderate degree of dispersion.

地径和胸径的增幅显著增加，下图清晰地展示了2019 - 2025年间平均地径和平均胸径的增长趋势。数据表明，这两个指标在这些年份中均有显著增长，尤其是在2024年和2025年。
The growth in basal diameter and DBH are significant. The image below clearly illustrates the growth trends of the average basal diameter and average DBH from 2019 to 2025. Data shows that both indicators have experienced substantial growth during these years, with particularly prominent increases in 2024 and 2025.

林地内地形起伏显著导致林地密度空间分异明显，局部区域林木分布密集，部分区域则相对零散。这种密度差异进一步引致抚育质量的空间分异，最终表现为不同区域林木生长速率的显著差异。根据夏季实地调查显示：樟子松整体生长态势良好；柠条生长迅速，生物量积累显著；地表植被恢复成效突出，沙土裸露面积显著减少，沙化趋势得到有效控制。综上，该区域生态恢复成效显著。
The significant topographical fluctuations within the forest had led to distinct spatial differentiation in stand density, with trees densely distributed in some areas while being relatively scattered in others. This density variation had further resulted in spatial disparities in nurturing quality, ultimately manifesting as significant differences in tree growth rates across different areas. According to the survey in summer: the overall growth of pines was robust; Caragana microphylla was growing rapidly with substantial biomass accumulation; and the restoration of surface vegetation was remarkable. The area of bare sandy soil had decreased significantly, effectively curbing the desertification trend. In summary, the ecological restoration in this region has achieved remarkable results.

该林地为封育林地，内部放牧痕迹轻微，对樟子松生长影响有限。封育措施促使植被高度郁闭且物种丰富度高。后期抚育需聚焦以下重点：观测人为干扰和防火。
The forest was an enclosed forest, with minimal evidence of grazing and limited impact on the growth of pines. The enclosure measures had facilitated high vegetation closure and significant species richness. Future nurturing should focus on the following priorities: monitoring anthropogenic interference and strengthening fire prevention.
