摘要:
利用ArcView3.3对鄂西三峡库区1999年森林资源二类调查成果和遥感判读样点数据进行处理和分析,提取了森林资源分布图、林龄结构分布图、郁闭度分布图等系列森林景观图,为研究该区域内的树种结构、径级结构、林龄结构和林种结构等森林资源结构及其空间分布提供了可视化的基础。结果表明①鄂西三峡库区森林植被类型较多,特有植物多,库区森林覆盖率为46.8%;②森林地理分布不均匀,主要分布在二高山地区;③地带性植被落叶常绿阔叶林遭受破坏严重,森林具有明显的次生性,灌木林和针叶林所占比重较大;④林种结构不合理,防护林、经济林比重小,用材林比重大,近成过熟林比重较小;⑤林龄结构方面,中幼龄比重较大;⑥鄂西三峡库区森林植被对库区生态环境的保护功能不能很好的发挥。
Abstract:
By processing and analizing the remote sensing interpretation data and the forest inventory data of the Three Gorges reservoir area in western Hubei in 1999 by ArcGIS, the forest resources distribution map, age structure map, a series of forest canopy density distribution landscape map were extracted to study forest resources structures, such as the tree types structure, the diameter level structure, the age of forest structure and the forest plants spatial distribution and so on. The structures provided the visualization foundation in this region. The forest resources spatial structure research, to display forest function and to manage the forest resources. Analysis data show that ① There are multiple types of forest resources and more endemic plants, the coverage rate is relatively high(46.8%). ②The geographical distribution of the forest is quite uneven, mainly in the mountains. ③ The zonal evergreen broadleaved forests have been seriously damaged, and the forests have obvious secondary features, with shrubbery and coniferous forest accounting for the greatest proportion of the forest. ④ Forests structure is not very reasonable, the area of the timberforest is much larger than that of shelterforest and economic forest, whether the forest area or the reserves, the nearly mature forest or too mature forest shares a smaller proportion. ⑤ As for the age structure, youngandmiddle age forests account for greater proportion than nearandover matured forest. ⑥The forest cover protection function of the ecological environment in the Three Gorges reservoir area is not playing well.
