Abstract:

【Objective】 This study aimed to understand the recent status and changes of forest quality in Xinjiang. 【Method】 First, data on approximately 40 000 plots of Xinjiang forest with continuous inventory in 2001, 2006, 2010 and 2016 were extracted, and principal component analysis was used to propose influencing factors, such as average tree height, average diameter at breast height, age group, tree species, canopy density, accessibility, naturalness, regeneration grade and health grade. The dynamics and influencing factors of forest resource qualities in each year were analyzed. 【Result】 The results showed that the influence of forest structure on forest quality was greater than that of the forest productivity, and the influence of both were far greater than that of the forest stability and forest ecological influence on forest quality; the indexes of average tree height, average diameter, canopy density and age group were significantly affected. 【Conclusion】 This comprehensive analysis revealed improvement in forest quality over 2001-2016.However, some significant differences in forest quality remained in different regions. The areas of Aletai, Yili State of Xinjiang, Mongolian Autonomous Prefecture of Bortala, Changji Prefecture, north of Bayinguoleng were high quality, and presented high levels of comprehensive and dense distribution, followed by Akesu, Tacheng and Kiz Kirgiz Autonomous Prefecture. Forests in southern Xinjiang, which were sparsely distributed with relatively low forest quality.
