Effects of Different Slope Directions on the Growth of Larix principis-rupprechii
摘要
Abstract
[Objective] To study the effect of slope direction on Larix principis-rupprechii forest.[Method] The Larix principis-rupprechii of North Ditch Forest Farm was researched as an object with the standard survey method,and the survey based on the investigation data of the Larix principis-rupprechii and chose average tree stem analysis of different slope,to find out the basic characteristics of the growth of individual trees by searching the larch plantation of DBH and tree height and volume variation.[Result] The results showed that in shady slope and sunny slope forest,the growth trends of DBH,tree height and volume was generally accordant,shady slope conditions of DBH,tree height and volume were higher than that of sunny slope;generally speaking,the shady slope had a certain extent of influence on DBH,tree height and volume of Larix principis-rupprechii,but volume's average increment and successive increment on the shady slope were significantly greater than on the sunny slope,in 35 or 30 years,the average increment and successive increment of volume on the shady and sunny slope had an obvious difference,which was respectively 0.001 4 m3 and 0.003 2 m3.[Conclusion] The Larix principis-rupprechii of DBH,tree height and volume on the shady slope had more obvious advantages than on the sunny slope.关键词
