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。而2016-1相对平整，灌溉条件较好，主体造林树种为樟子松。
Cooperating with the Forestry Bureau in Keerqinzuoyihou Qi, Tongliao, MTP contributed to the ecological restoration of 2 sandy land plots in 2016, including scotch pines, poplars and elms. The two plots were adjacent to each other and had similar standing conditions, while 2016-1 was relatively flat and irrigated, with the pine as the main afforestation species.

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%。2016-1各样地保存率变化可见下图，可以看到，大部分区域的保存率基本没有发生变化，保存率非常稳定。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
松树的生长情况良好，底部枝条相对茂盛，部分林木需要进行修枝，树行清晰。
The pines were in good condition, and a lot of branches were accumulated on the bottom. Some trees needed to be pruned. The rows of trees were very clear.

走访过程中发现林地内出现了较多放牧现象。林地内植被情况较好，大部分区域的裸露地表均有较厚枯枝落叶和草本植物覆盖。林地内缺损苗木的区域和树行中间补植了部分刺榆等本土树种。
During the forest visit, some grazing was founded in the forest. The vegetation of the forest was in good condition, with a thick cover of dead leaves and herbaceous plants on the bare ground surface in most areas. The missing seedling areas and the middle of the tree rows were partially replanted with native tree species such as elm.
