林地生长数据 Forest Growth Data
2016年，MTP项目与内蒙古通辽市科尔沁左翼后旗林业局合作，在2个沙荒地进行了生态修复，造林树种包括杂交杨树、榆树和樟子松。两块林地相邻，立地条件类似。
Cooperating with the Forestry Bureau in Keerqinzuoyihou Qi, Tongliao, MTP carried out afforestation work on two sandy land plots in 2016. The tree species included scotch pines, poplars and elms. The two plots were adjacent to each other and had similar conditions.

2016年林地在2024年度的总体成活率为72.86%。其中，2016-1保存率为64.17%，2016-2的保存率为79.38%。2016-2各样地保存率变化可见下图，可以看到，各样地的保存率变化较小。样地间差异较大，靠近道路的样地抚育质量较高，保存率稳定，林地保存率水平基本维持在60%以上。
In 2024, the overall survival rate of 2016 Forest was 72.86%. The survival rate for 2016-1 was 64.17% and for 2016-2 was 79.38%. The survival rates of each sample sites in Plot 2016-2 are shown in the below graph. It shows that the survival rates of each sample sites did not change much indvidually. But there were huge differences between each sample site. The maintenance of the sample sites close to the roads were better than the others. The survival rates of all the sample sites were maintained over 60% in general.

2016年两块林地的各树种树高均值都在增长，樟子松的增幅较大；榆树在2021年之后逐渐稳定，进入增长期。樟子松的地径和胸径均值增幅较大，表明林地内樟子松在显著地增粗，其均值甚至大于杨树。杨树的地径和胸径增幅缓慢，情况稳定。榆树进入一个较快的增长期，两项指标显著提高。
The average tree heights of all species increased in both forest plots, with a greater increase in pines. And elms were gradually stabilized after 2021 and entered a rapid growth period. The increase in the growth of average basal diameter and diameter at breast height (DBH) of pines indicated that the pines were growing significantly. These two average values were even greater than those of poplars. Poplar had a slow increase in basal diameter and DBH, which was in a stable stage. Elms had entered a faster growth period, with significant increases in both indicators.

林地情况说明 Forest Description
杨树生长相对健康，发芽情况良好，部分杨树树高增长非常快，达10米左右。榆树的生长有明显改善，林地内补植的樟子松情况良好。
The poplars were in good health and sprouted well. A part of the poplars grew very fast, up to about 10 meters high. The growth of elms had improved significantly and the replanting of pines in the forest was in good condition.

走访过程中发现，林地内原本缺损苗木的区域补植了刺榆和五角枫，部分区域补植了杨树。杨树生长呈现区域性差异，部分区域生长高大，部分区域依旧低矮。榆树生长情况逐渐稳定。林地内出现一些放牧迹象，少量杨树和榆树都有被啃食树皮的情况发生，需要进一步加强抚育封育等措施。
During the forest visit, it was found areas that had been missing seedlings were replanted with elms and maples, and some areas were replanted with poplars. The growth of poplar showed differences from region to region, with some areas growing tall and some remaining low. The growth of elm was gradually stabilized. There were some signs of grazing in the forest, and a small number of poplar and elm barks had been eaten, requiring further monitoring measures such as enclosure.
