矿山矸石台地植被恢复栽培模式研究

In order to study 5 cultivation models such as arbor-shrub, arbor-shrub-herb and their disposition for vegetation recovery, 10 arbor species, 7 shrub species and 5 herb species suitalde for locat sites were choiced at waste heap platform of Fushun Coal Mine. The experiment adopted the randomized block design, three replicates, with 0.067 hm^2 at each thinned plot. The experiment results of 2-year vegetation recovery showed that the survival rate of woody plants was significantly different among species and there existed significant differences in ground diameter and height increments. The results of the initial stage of the experiment showed that the disposition of A and C were the optimal cultivation models, and Robinia pesudoacacia, Hippophae rhamnoides,Amorpha fruticosa, Caragana chamlagu, Ulmus pumila were the best tree species for arbor-shrub-herb disposition.

废弃矸石台地营造坑木用材林技术

为了探索在进行生态恢复的同时,获得必要的经济收益,我们在废弃矸石台地进行了营造坑木用材林的试验研究。经过近30a的观测研究,总结出可用于本地区矸石台地营造坑木用材林的树种及主要技术措施,可为在相似立地条件下营造坑木用材林提供技术支持。

抚顺西排土场人工林植被恢复调查与分析

对抚顺市西排土场顶部矸石山台地上8个林种人工林林下植物群落的物种组成、数量、盖度、密度、频度、高度等进行调查,分析了各物种的群落重要值及各林种林下群落α多样性指数。结果表明:造林初期人工林下自然植物群落组成以菊科、萝藦科、藜科植物为主。与自然恢复的裸地相比,5个林种人工林下植物科数增加,1个林种林下植物科数减少;3个林种人工林下植物种数增加,2个林种人工林下植物种数减少。林下植物群落α多样性指数,人工纯林总体高于混交林。在该立地条件下,宜重点营造刺槐、家榆、紫穗槐、锦鸡儿林,并采用以纯林为主,乔灌混交、乔灌草混交为辅的配置方式。
