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。2016-1、2016-2两块林地相邻，立地条件类似；林地道路网络完善，抚育条件优良，整体保存状况良好。
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. And the plots also had a well-developed road network, excellent nurturing conditions, and was in good overall condition.

两块林地的保存状况已趋于稳定，未出现大面积死亡或补植现象；保存率的轻微波动主要源于采样区缩减带来的数据误差，该误差处于可接受范围。2016-1林地在2025年度的成活率为64%。
Survival rates in the two plots have reached a steady state, with no significant die-off or additional replanting required. Slight variations in survival data are mainly due to the downscaling of sampling sites rather than actual tree loss, and these fluctuations are within acceptable limits. In 2025, the overall survival rate of 2016-1 Forest was 64%.

树高变化和去年的趋势相同，两块林地的各树种均值都在增长；樟子松的增幅较大；榆树在2021年之后逐渐稳定，进入增长期。
The trend in tree height remains consistent with that of the previous year, with the average heights of all species in both plots showing growth. The increment in pines is particularly pronounced. Since 2021, the elms have gradually stabilized and entered a steady growth phase.

从上图可见，樟子松的地径和胸径均值显著增加，仍处于快速生长期；杨树生长增速逐渐放缓，地径、胸径增幅趋于稳定；榆树则逐步进入增粗生长期，两项指标显著提升。
As illustrated in the figure above, the average basal diameter and DBH of pines have increased significantly, indicating that it remains in a rapid growth phase. Conversely, the growth rate of the poplars has gradually decelerated, with increments in basal diameter and DBH stabilizing. Meanwhile, the elms have progressively entered a thickening phase, characterized by a significant rise in both metrics.
整体来看，三个树种均处于生长期，但生长节奏差异明显：杨树虽为速生树种，当前阶段以高生长为主、粗生长较慢；樟子松保持快速增粗态势；榆树则刚进入粗生长加速期，反映出不同树种的生长节律特性。
Overall, all three species are in their growth phase, though their growth rhythms differ significantly. As a fast-growing species, the poplars are currently prioritizing height growth over radial growth. In contrast, pines maintain a rapid trend of basal thickening, while the elms have just entered an accelerated phase of diameter growth. These observations reflect the distinct phenological and growth rhythm characteristics inherent to each species.
林地情况说明 Forest Description
林地内樟子松生长状况整体良好：林木下部枝条较为繁茂，部分植株因枝条过密需适时开展修枝作业；林分株行距清晰，林相整齐。林下草本植被覆盖度较高，生物多样性良好，但存在少量放牧活动痕迹，对局部林木造成轻微损伤（主要表现为树皮啃食或下部枝条折损）。当前林地主要风险点为森林火灾隐患，需重点加强防火巡查与可燃物清理。
The overall growth condition of pines was robust: the lower branches were flourishing, and pruning was required for certain individuals due to excessive branch density. The stand showed clear spacing and a uniform appearance. The understory herb layer was in high coverage and good biodiversity; however, there were minor traces of grazing, which had caused slight localized damage (primarily manifested as bark gnawing or broken lower branches). The primary risk at present is the potential for forest fires, necessitating a focus on intensified fire patrols and the removal of combustible materials
