2021-1林地为MTP项目与内蒙古通辽市科尔沁左翼后旗金宝屯镇新建村村民合作造林的林地,在一块荒地上进行防护林营造。该林地位于辽河附近,村庄南侧,将东西两侧大面积农田分割,阻断该区域农田春冬季的风蚀。由于地势平坦,且靠近河流,造林树种以生长迅速的杂交杨树为主。
The 2021-1 Plot was the forest that MTP had carried out ecological restoration in one barren land, in cooperation with the villagers of Inner Mongolia Korqin Zuoyi Houqi Jinbaotun. The site is located near the Liao River and on the south of the village, dividing a large area of farmland on the east and west sides, and blocking the wind erosion of farmland in spring and winter. Since the terrain is flat and close to the river, the planting species are mainly hybrid poplars that grow fast.
2022年度通辽地区夏季降雨量大,降雨时间长,该地块部分区域发生内涝,该区域内的林木由于长时间浸泡而死亡。在2023年度秋季和2024年春季该林地进行了大面积补植,总体保存率为90%。2024年度全林地抽样调查中各样点的保存率也普遍较高,补植的质量较好,保证了林地整体保存率。
In the summer of 2022, there was continuing heavy rainfall in the area. The trees were damaged and died after being flooded for a long time. In the fall of 2023 and spring of 2024, the forest was replanted, and the survival rate of Plot 2021-1 in 2024 was 90%. Survival rates were also generally high across the sampled sites in the 2024 forest-wide sample, and the quality of replanting was good, ensuring the overall forest survival.

由于补植过程中,选取的为1-2年生裸根苗,并采用了截杆措施,所以,大部分苗木的树高数值偏低,导致均值偏低;而高于1.3米(胸径测量位置)的杨树为往年栽植的,生长了3年,整体生长数据较高,但数量较少,胸径均值主要体现这部分杨树的情况。这部分杨树的平均胸径为1.91厘米。为了更直观的体现林地的差异,将测量杨树的树高值进行了总结如下:
Since the 1-year-old and 2-year-old bare-root seedlings and cutting measure were used to replant this forest, most of the tree height and the average values of tree height were low. The poplars higher than 1.3 m (location of the diameter at breast height) were planted in previous years and had grown for 3 years, with higher overall growth data but in smaller numbers, and the diameter at breast height averages mainly reflect the condition of these poplars, which was 1.91 cm. In order to more visually represent the differences between the stands, the tree height values of the measured poplars are summarized below:

可以看到,林地大部分树高均集中在0.5-1.5米之间,这部分苗木为2023-2024年的补植苗木,截干处理使得树高集中在1.5米以下,利于杨树苗木的根系生长。往年存活下来的杨树树高分布较散,生长差异较大。
It can be seen that most of the trees are concentrated in the height of 0.5-1.5 meters, which are the replanting seedlings in 2023-2024, and the cutting measure makes the height of the trees concentrated in the height of less than 1.5 m, which is conducive to the root system of poplar seedlings. The height distribution of the poplar trees from previous years is more scattered, and the growth difference is larger.
林地由于靠近辽河,在2023年度夏季多雨的影响下,道路始终不通畅,在2023年秋季和2024年春季对林地完成了全面补植。
As this forest was near the Liao River, the road to forest was always be blocked in the 2023 rainy summer. Full replanting of the forest was completed in the fall of 2023 and spring of 2024.

林地采用拉沟补植,进行了截干处理,春季发芽情况良好,树行清晰;但在秋季调查中发现,由于林地原本属于农田,在2024年度停止种植农作物之后,杂草生长非常茂盛,大量的苗木被杂草掩埋缠绕,导致小部分苗木死亡。综上所述,该林地立地条件好,补植质量也较好,林地整体生长较乐观。但依旧处于林地初植期,相对脆弱。在客观因素上,林地依旧存在内涝风险,过密的杂草也需要进行相应的除草抚育。
The fores was replanted by pulling ditch and cutting measure, with good germination in spring and clear tree rows; however, it was found in the fall survey that since the forest originally belonged to farmland, after the cessation of crop planting in 2024, the weed growth was very luxuriant, and a large number of seedlings were buried and entangled by weeds, resulting in the death of a small portion of the seedlings. In summary, the forest is in good condition, the quality of replanting is also good, and the overall growth of the forest is optimistic. However, it is still in the initial planting period and is relatively fragile. In terms of objective factors, the forest is still at risk of waterlogging, and the dense weeds need to be weeded and nurtured.
