2019年,MTP项目与内蒙古通辽市科尔沁左翼后旗林业局合作,在1个沙荒地进行了生态修复,林地东侧为高速公路,北侧为高速公路辅路,造林树种包括樟子松、五角枫、小叶锦鸡儿等,其中主体造林以樟子松为主,间种少量五角枫,沙化严重的区域栽植小叶锦鸡儿。

Cooperating with the Forestry Bureau in Keerqinzuoyihou Qi, Tongliao in 2019, MTP contributed to the ecological restoration of one sandy land plot by planting a mix of Pinus sylvestris L. var. mongolica Litv. (scotch pines), Acer mono (maples) and caragana microphylla Lam. As shown in the picture 1, there is a highway located in the east part of plot, and the side road of the highway is located in the north part of the plot. The main species is scotch pine, with few maples in-between. And caraganas were mostly planted in severe desertified area.

项目计划共造林1709亩,樟子松9万余棵,樟子松平均保活率为60.94%。五角枫和小叶锦鸡儿占比较低且分布零散,无法直接核算,暂时不纳入本次调查。

The forest covers 113.9 hectares, with over 90,000 scotch pines of 60.94% average survival rate. Acer mono (maples) and caragana microphylla Lam are not calculated in this report due to few numbers of trees and scattered location.

林地情况说明 Forest Description
林地主体造林为樟子松,同时间种少量五角枫,在坡度较大的区域栽植小叶锦鸡儿巩固沙丘。由于五角枫和小叶锦鸡儿的造林数量相对较少,且相对分散。主要观察和记录的是樟子松的情况。

The main species is scotch pine, with few maples in-between. And caraganas were mostly planted in slopes for consolidating dunes. But we mainly observe and record the conditions of scotch pines due to few numbers of maples and caraganas and their scattered location.

由于林地内部地势较复杂,坡地多,大面积的空白区域较少,很大程度上影响了栽植质量和抚育质量。由于选用的是相对大一点的苗木,其抚育的质量和频度也较高,因此相对平坦和靠近道路区域,樟子松的栽植质量较高。这导致林地松树区域间生长差异加大。

There are few large blank areas because of the complex terrain and a number of slopes, which largely influences the quality of planting and maintaining. However, the scotch pines close to roads and on flat areas are with high qualities. The reasons are that elder saplings are planted in these areas and the quality and frequency of maintaining is relatively high. This strengthens the differences of scotch pines between different areas.

图4为刚完成栽植的照片,能够看到明显的栽植树行;图5为雨季相同位置的照片,地面其它植被生长茂盛,遮盖了部分樟子松苗木。因为林地平坦区域的降雨接收能力较好,受抚育的影响较大,植被恢复程度较高,对樟子松造成了一定程度的遮挡。

Through image 4, which are newly planted trees, we can see saplings clearly row by row; Image 5 was taken in the same location in wet season, as shown in the picture, some pine saplings are covered by some other flourishing plants. That is because flat areas have better capacity on rainfall storage, and influenced by more frequent maintenance, which result in high vegetation restoration in these areas, causing some scotch pines under shelter.
