2012-1、2012-2、2012-3、2012-4为一组，其合作方为库伦旗六家子林场，林地功能为碳中和。 2012-2林地中，杨树成活率为91%，樟子松成活率为64%，基本与去年持平。杨树生长稳定，三项指标的生长还会继续，树高超过1.3米的苗木比例较高，且基本稳定。樟子松情况逐渐稳定，生长加速。

In an effort to offset carbon dioxide, Plot 2012-1,2012-2,2012-3 and 2012-4 were planted in cooperation with Liujiazi Tree Farm back in 2012. The survival rate of poplar is 91% and of pine is 64%, remains the same as last year. The growth of poplar is steady and the growth of the main indexes will continue. The proportion of trees with a height more than 1.3m is relatively high and basically stable. The situation of pines is steady and the growth has accelerated.

杨树底部消耗枝和竞争枝较多，生长情况良好。樟子松留存的参差不齐,大部分区域的林地间种退出，樟子松的新损失情况减少，开始稳定生长。

Generally speaking, the overall situation is stable. Poplars have too much branches towards bottom, but the growth situation is good. Pines retained uneven, most areas of woodland species quit, reduce the loss of new cases of pines, begin to grow steady.
