摘要：

依据2018年西北监测区人工造林综合核查结果,对西北干旱区2008—2012年人工造林保存和成林率调查结果进行统计分析,总结了西北干旱区人工造林保存和成林率主要特点,并从干旱等自然灾害、适宜造林地、幼树生长状况、后续管理、林分结构等方面深入剖析了区域内影响人工造林保存和成林的主要原因。提出了提高中央投资标准,加强造林后续管理,科学合理布局造林,宜乔则乔、宜灌则灌、宜封则封等建议。

Abstract:

Based on the results of comprehensive verification of plantation in Northwest monitoring area in 2018,this paper makes a statistical analysis of the results of the investigation on the preservation and afforestation rate of plantation in northwest arid area from 2008 to 2012,and summarizes the main characteristics of the preservation and afforestation rate of plantation in Northwest arid area.The main factors affecting the preservation and afforestation of plantation in the region were analyzed from the aspects of natural disasters such as drought,suitable afforestation land,growth status of young trees,follow-up management and stand structure.Suggestions were put forward to improve the central investment standard,strengthen the follow-up management of afforestation,scientifically and rationally arrange afforestation,take correspording vegetation restoration measures according to different corditions.
