贵州平塘县森林资源现状
|
摘要
为贵州喀斯特地区林业可持续发展提供参考,以2016年平塘县森林资源二类调查数据为依据,对平塘县森林资源现状与特点进行分析。结果表明:平塘县林地面积210 528.14hm2,以防护林和用材林为主,面积分别为130 395.17hm2和65 797.06hm2,占林地总面积的93.19%;林地主要分布在海拔1 000～1 200m区域,其次是海拔800～1 000m的区域,林地面积分布最少的是海拔400m以下区域。林地面积随坡度的增大而增加,分布面积顺序为险坡>急坡>陡坡>斜坡>缓坡>平坡。
The current situation and characteristics of forest resources in Pingtang County are analyzed on the basis of class II survey of forest resources in 2016 to provide a reference for sustainable development of forestry industry in karst region in Guizhou.Result:The forestland area is 210 528.14 hm2 in Pingtang County.The area of the protection forest and commercial forest is 130 395.17 hm2 and 65 797.06 hm2 respectively and accounts for 93.19% of total forestland area.The forestland distributes in the areas with an elevation of 1 000-1 200 mmainly,followed by the areas with an elevation of 800-1 000 m.The least distribution of forestland area is in the areas with an elevation<400 m.The forestland area increases with slope increment.The forestland distribution area of different landform is dangerous steep slope > steep slope>abrupt slope>slope> gentle slope>flat slope.
