2013年林地情况汇总

百万植树计划自2007年以来,七年间共完成24块林地的造林工作,栽植面积为17794.4亩(1186.29公顷),总计造林1293409棵。栽植树种共4种,分别为杂交杨树、文冠果、五角枫、樟子松。

Launched in 2007, the Million Tree Project has successfully planted 1,293,409 trees with a total scale of 1,186 hectares at 24 plots in Tongliao Municipality, Inner Mongolian. Hybrid poplars, yellow horn, mono maple, pines were planted with the proportion of 66%, 6%, 1% and 27%.

在2013年9月到11月之间,百万植树计划林业主管及技术专员对24块林地进行了全面的走访调查及实地测量。测量结果显示,林地的总体保存率达到78.57%。项目组把2011至2013年的成活率进行了对比,结果如下图。

From September to November 2013, our forestry specialists carried out onsite inspections and conducted annual investigation at all 24 plots. Statistical results show that the average survival rate has reached 78.57%. The survival rate of each plot is shown as below. Compared with previous investigation data, forests are growing stably in 2013.

测量及对比结果显示,2013年林地总体处于良好状况。根据《造林技术规范》GB/T 15776-1995人工造林评定标准,年降雨量在400mm以下地区,成活率在70%以上(含70%),为造林合格。部分地块存在间种人为破坏问题,同时间种作物的种类对林木的生长也造成一定影响。杀虫剂及农药的不规范施用也对林木的生长存在威胁,我们会在日后的工作中,加强与合作方的沟通,加大对当地农户的教育及监管,以确保林木处于良好的生长状态。

Generally, all plots are in good conditions in 2013. According to standards from Technical Guidelines for Afforestation GB/15776-1995, it’s a successful sign that survival rate of afforestation reaches 70% in the area where average precipitation is less than 400mm. Although overall survival rate of 24 plots reached to 78.57% in 2013, still existing problems shouldn’t be ignored. Unregulated operation remains in part of the forests; intercropping species and the application of pesticide and insecticide on the crops threaten the forest in some way. In 2014, MTP team will carry out more frequent communications with local partners and enhance trainings and supervision for the local planters to ensure the forest continues to be under ideal conditions.
