2025年，MTP与内蒙古通辽市科左后旗农户合作，在3块退化林地更新区域开展生态修复工作，主要栽植适应当地气候的杨树，辅助搭配刺榆、五角枫等低耗水、耐旱的原生树种（因数量较少未纳入主要统计）。三块林地均分布在科尔沁左翼后旗吉尔嘎朗镇周边区域，原为退化林地，立地条件基础较好——地形相对平坦，地表裸露程度较低；但土壤中残留大量树根，导致栽植作业难度较大。此外，因距村庄较近，存在轻度放牧干扰。
In 2025, cooperating with the local farmer in Horqin Zuoyi Houqi, Tongliao City, Inner Mongolia, MTP contributed to the ecological restoration in three degraded forest renewal sites. All the three plots were near the Jiergalang Town and the main species was poplars adapted to the local climate, supplemented by drought-tolerant native species with low water requirements such as elms and Acer mono (maples). (These were not included in the main statistics due to their small number). The three forest plots restored in 2025 was originally degraded forest with relatively good conditions—relatively flat terrain and low surface exposure; however, a large number of tree roots remained in the soil, making planting operations more difficult. In addition, due to its near to villages, there was slight disturbance from grazing.

从图2可知，三块林地的保存率差异显著：2025-1地块初植保存率处于较高水平，达到86%。2025-3地块达到合格标准，2025-2地块仅略高于50%。
As shown in Image 2, the survival rates of the three forest plots differed significantly: Plot 2025-1 had a relatively high initial planting survival rate, reaching 86%. Plot 2025-3 met the acceptable standard, and Plot 2025-2 was slightly above 50%.

在调查过程中，样地内存活棵数不足总棵数50%的，视为成活情况不达标。现将三块林地各样地的达标比例统计对比如下：
During the survey, sample sites with less than 50% surviving trees were considered to have failed to meet the survival standard. The compliance rates of various sample sites in the three forest plots are statistically compared as follows:
表 1.样地达标比例
Table 1. The compliance rates of the sample sites in three forest plots
从上表可以看到， 2025-1和2025-3的采样样地均全部达标。而2025-2则仅57%达标，说明该林地存在大面积苗木死亡的情况。
As can be seen from the table above, all sample sites in 2025-1 and 2025-3 met the standards. However, only 57% of the sites in 2025-2 met the standards, indicating that there was a large-scale seedling mortality in this plot.
本年度林地采用高密度机械栽植方式，栽植的杨树为1-2年生裸根苗，大部分苗木在栽植时进行了截干处理。所以测量所得的苗木整体规格偏小，树高、地径、胸径等生长指标均值均较低（具体数据见表2）。受截干处理影响，林地苗木的树高、地径、胸径等生长指标数据暂无法准确反映其实际生长状况，需经过一段时间的生长积累后再行评估。
This year, high-density mechanical planting was used in the plot with 1-2 year old bare-root poplar seedlings. And most of the seedlings were planted with stem-cutting treatment, so the seedlings were small, and the average values of tree height, basal diameter, diameter at breast height(DBH), and other indexes were all low (as shown in Table 2). Due to the impact of stem-cutting treatment, the growth indicators of seedlings, such as tree height, basal diameter, and DBH, cannot accurately reflect their actual growth status. They need to be evaluated after a period of growth accumulation.

林地情况说明 Forest Description
2025-1林地位于吉尔嘎朗镇西北，面积311亩，主要栽植为杨树和少量榆树。距离村庄较近，周边大部分区域为农田。
Located in the northwest of Jiergalang Town, Plot 2025-1 covered an area of 20 hectares and was mainly planted with poplars and a small number of elms. It was close to the village, and most of the surrounding area was farmland.

林地树行间原有树根萌发了大量萌蘖枝，杂草生长茂密；同时，新栽植苗木的发芽状况良好。
Numerous suckers sprouted from the original tree roots between the rows of trees in the forest, and weeds grew densely; at the same time, the newly planted seedlings sprouted well.

林地内杂草生长茂密，虽对杨树苗木造成一定影响，但程度有限；不过，茂密的杂草也增加了火灾隐患。目前林地整体状态相对健康，需持续开展抚育管理（如杂草清理、苗木管护等），以巩固当前成果并降低风险。
The poplar seedlings were influenced by the dense weeds, but the extent was limited; however, a large amount of weeds also increased the risk of fire. Currently, the overall condition of the forest was relatively healthy, and continued nurturing and management (such as weed clearing and seedling maintenance) was necessary to consolidate current achievements and reduce risks.
