摘要:
选择正确的栽植树种是石漠化生态系统植被恢复的关键。 树种, 文章 为了筛选粤北石漠化地区生态修复 以粤北石漠化地区植物样地调查数据为基础, 选取了重要值、 胸径、 树高、 枝下高、 冠幅、 碳储量为评价指标, 应用熵权-TOPSIS 综合评价法进行树种选择。 研究结果表明: 石漠化地区植物多样 性低, 进行植被恢复时, 在 “适地适树” 的原则上应优先考虑乔木树种湿地松 Pinus elliottii、 马尾松 P. massoniana, 灌木树种檵木 Loropetalum chinense、 盐肤木 Rhus chinensis 作为粤北石漠化植被恢复选择 树种; 杜英 Elaeocarpus decipiens、 桂花 Osmanthus fragrans 树种可作为石漠化树种选择的辅助和补充。

Abstract:
Selection of correctly planted tree species is the key to vegetation restoration. This paper is on the survey da based ta of plant sample plots in rocky desertification areas of northern Guangdong was employed to establish tree species selection and evaluation model, with integrating the six quantitative factors involving importance valve, diameter, tree height, height to crown base, crown width, carbon stock. Application of entropy weight-TOPSIS comprehensive evaluation method to tree species selection, on the basis of the estimated values. The results show that: The plant diversity in rocky desertification areas is low, so when vegetation restoration is carried out, in the principle of “ suitable land and suitable trees ”, tree species such as Pinus elliottii P. massoniana, Loropetalum chinense, and Rhus chinensis can be used as the main extension tree species. Tree species Elaeocarpus decipiens, Osmanthus fragrans, can be used as supplementary tree species.
