摘要
介绍关岭县森林资源现状及1995～2005年的森林资源动态变化,通过对林地面积、森林蓄积量、森林覆盖率、森林健康度、森林自然度、森林景观及生态功能等指标的客观分析,得出结论:①林地质量逐步提高:2005年林地面积、森林蓄积量、森林覆盖率较1995年分别有所增加;②森林比较健康:乔木林中森林健康度为Ⅰ的占99.95%;③森林群落结构简单、林相单一、生态功能等级差:乔木林中自然度为Ⅱ的占0.06%,森林景观等级为Ⅱ的占1.31%,森林生态功能等级为Ⅰ的占0.06%。
The forest resource status in Guanling County and dynamic change during 1995-2005 was introduced.The conclusions are drawn by objective analysis of the indicators such as woodland area,forest volume,forest coverage,forest health degree,forest naturalness,forest landscape and ecological function： ① Woodland quality gradually increased： the woodland area,forest volume and forest coverage increased;② Forest are relatively healthy： forest health degree forⅠaccounted for 99.95% among arbor trees;③ Simple structure of forest communities,single forest,low level of ecological function： forest naturalness for Ⅱ accounted for 0.06%,forest landscape for Ⅱ accounted for 1.31%,forest class of ecosystem function forⅠaccounted for 0.06% among arbor trees.
