林地生长数据 Forest Growth Data

2009年共有三块合作林地,合作方均为库伦旗先进苏木的先进林场。造林树种为杨树与文冠果,文冠果分为2009-1与2009-2两块(因树种相同且地块位置、情况相近,以下按往例将2009-1与2009-2地块的数据一并计算,注记为2009文冠果)

In 2009, Poplars were planted on Plot 2009-3 while Yellow horns were planted on Plot 2009-1 and Plot 2009-2 in cooperation with the Forestry Bureau in Xianjin Sumu, Kulun Qi, Tongliao. This report represents the condition of both plot 2009-1 and 2009-2 since these two plots share similar external factors.

2009文冠果基本稳定在70%左右。文冠果树高始终保持着缓慢的增长,其中2009-2的树高增长停止,这主要是源于样地减少带来的测量误差。冠幅随着年份,生长逐渐放缓,而且两块林地逐渐趋同。

The survival rate of Yellow horns on Plot 2009-1&2 remains at round 70%. The growth of height in plot 2009-2 has stopped. This is due to the measurement error caused by the reduction of sample plots. The growth of the crown width has slown down with year, and the two plots gradually converge.

林地情况说明 Forest Description

2009-1林地还保持着间种,靠近间种一侧的横向冠幅会被限制扩张,如被农业机械剐蹭断裂等。

In plot 2009-1, forest is still in intercropping. The crown on the side of the interplanting is restricted to expand through methods such as agricultural cutting machinery.

2009-2的情况可从图中看到,苗木的分布零散,区域不均衡,同时苗木之间的差异也比较明显。

The situation of plot 2009-2 can be seen from the figure, the distribution of seedlings is scattered, there is regional imbalance, and the difference between seedlings is obvious.
