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。
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. 2016-1相对平整，灌溉条件较好。在2022年度，2016-1保存率为61.21%，有小幅上升，各样地保存率变化可见下图。可以看到，2016-1大部分区域的保存率基本没有发生变化，保存率的上升主要源于4号样点的补充测量，这使得林地整体的保存率离真实保存率更接近。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%左右。 The 2016-1 plot is relatively flat, and convenient for irrigation. In 2022, the survival rate of 2016-1 plot was 61.21%, which increased a little. The survival rates of each sample sites in this plot are shown in the below graph. It shows that most of the sample sites remained the same in the survival rate. The increase was due to the measurements of No. 4 sample site added to the forest survey. In this way, the overall survival rate was more accurate. 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 around 60% in general.
