摘要
采用广西东部低山丘陵地区森林资源连续清查的固定样地数据,采用数量化分析文法,结合林地实际情况,对该区域现有林地进行质量评价及等级评定。评定结果,一级质量的林地为2.14万hm2,占全区林地面积的0.74%;二级质量的林地为153.75万hm2,占53.08%;三级为121.38万hm2,占41.90%;四级为12.23万hm2,占4.22%;五级为0.16万hm2,占0.06%。文章就林地分等技术体系、基准树种以及多树种代换评价立地质量等问题进行了讨论。
Based on data from the continuous forest inventory of Guangxi province, the forestland quality was assessed by quantitative analysis method in study area. The results showed that first quality of forest land was 21 , 400 hm^2, accounting for 0.74% of the region＇ s forest land area; second quality of forestland was 1 , 537, 500 hm^2, accounting for 53.08% ; third quality of forestland was 1 , 213, 800 hm^2, accounting for 41.90% ; fourth quality of forestland was of 122, 300 hm^2 , accounting for 4.22% ; fifth quality of forestland was 1 , 600 hm^2 , accounting for 0.06%. Issues of Woodland grading system, site quality assessment under standard tree species and multi-species conditions were discussed.
