该林地在2013年重新补植的樟子松,并且大部分年份间种的均为高杆作物,导致其保存情况的变化极大。其中2018-2019年由于道路气候等原因,未进行测量,在2020年度该林地测量所得的保存率为60%,林地进行了一定程度的补植。该林地栽植的全部为樟子松,樟子松的生长速度较慢。由于受间种的影响,樟子松的树高在前几年几乎停滞,在今年的测量中有了明显的提升,进入正常生长的状态,但均值从数值上看依旧偏低。地径受间种的影响相对较小,保持缓慢增长,在2020年度的涨幅非常显著。在2020年度,胸径均值为1.1cm,也是该林地第一次测量到胸径数据,占苗木总数的24%

The plot was replanted with pines in 2013. In most times, there interplanted with taller crops, which caused highs and lows in the survival rates. Because of the repairing roads and bad weather, we couldn’t conduct forest survey in 2018 and 2019. In 2020, the survival rate in the plot was 60%. There was replanting too. All the trees in the plot were pines, and pines grow slowly. Because of the interplanting, the pines were not growing very much in the pat few years. In 2020, the growth index had a significant increase, showing that they entered a normal growth phase. The average values were a bit low. The basal diameters were not affected by the interplanting like other indicators, and they kept growing slowly. The increase in 2020 was remarkable. In 2020, the average DBH was 1.1 cm. This was the first time that DBH could be measured in this plot, and the measurable trees took up 24% of all trees.

林地内间种的是矮杆的向日葵,与树行保持了相对健康的间距,樟子松存在一定程度的缺苗现象,留存的樟子松生长健康,补植的樟子松生长情况需要进一步观察。

The interplanted crops were short sunflowers, and there were proper distances between crops and tree rows to make room for trees to grow. There were some losses of saplings in the site. The remaining pines grew very well. The replanted pines needed further observation.
