摘要
利用湖北省太子山林管局1999年和2009年2期的森林资源二类清查及2006年调查数据资料,对10年来各类土地面积结构、森林资源结构(林龄结构和林种结构)和森林资源质量进行动态分析。结果表明:太子山林管局森林总面积、有林地面积和苗圃地面积增加,其他类型土地面积减小;幼龄林面积增加,中龄林和近熟林面积减少,且近熟林比重很小,林龄结构不尽合理;用材林比重下降,生态公益林面积增加;森林资源质量缓慢提升,高于湖北省平均水平,但仍低于全国平均水平。并从动态变化的结果提出相应的经营对策,以期调整林业结构,实现林业的可持续发展。
The structure of land area,forest resource and quality of forest resources were analyzed based on the forest resource inventory data of Taizi Mountain Forest management bureau in two periods including 1999,2009 and 2006.The results showed that the total forest area,forest land area and nursery area increased,and area of other land types decreased;Sapling forest area increased,but the area of middle age forest and near-mature stand decreased,the proportion of near-mature stand was low and the stand age structure was improper;the area of timber forest decreased while ecological forest increased;the quality of forest resources increased slowly and was above the average level of Hubei province but still lower than the national average level.The corresponding measures were put forward in order to adjust forestry structure and achieve sustainable development of forestry.
