[目的]研究新疆绿洲人工防护林体系特征。[方法]通过对比新疆维吾尔自治区森林资源连续清查(第2~8次)成果数据,对新疆干旱绿洲人工防护林林种、栽植面积、蓄积、龄组等特征进行分析。[结果]2011年人工防护林面积是1992年的2.2倍,蓄积是1992年的4.0倍;人工防护林龄组面积变化特征为初期以幼龄林为主,变化为以中、幼龄林为主,近、成熟林为辅的模式。人工防护林树种选择上由乔木、灌木、经济林树种逐渐转变为以乔木树种为主;人工防护林树种配置上由乔灌混交林逐渐过渡到以人工乔木为主的模式;人工防护林占农田面积由1992年的4.0%~5.0%提高到2011年的8.9%,防护效果显著。[结论]为新疆干旱绿洲人工防护林体系近年来的发展变化提供数据支撑。
[Objective] The research aimed to study the characteristics of artificial shelterbelt system in oasis in Xinjiang. [Method] The data of forest inventory in the Xinjiang Uygur Autonomous Region (2 ~ 8 times) were compared to analyze the characteristics of artificial shelterbelts, planting area, accumulation and age groups in Xinjiang arid oasis. [Result] The area of artificial shelterbelt in 2011 was 2.2 times that of 1992, and the stocking volume was 4.0 times that of 1992. The area of artificial shelterbelts was characterized mainly by young forest at the initial stage and mainly by middle and young forest. Nearly mature forest supplemented by the model. Artificial shelterbelt species selection by trees, shrubs, economic forest tree species gradually changed to mainly arboreal species; artificial shelterbelt species allocation by the gradual transition from the arbor mixed forest to artificial arbor-based model; artificial shelter accounted for the farmland area from 1992 4.0% ~ 5.0% to 8.9% in 2011, the protective effect is remarkable. [Conclusion] This provided data support for the development and change of Artificial Shelterbelt in drought oasis in Xinjiang in recent years.
