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。
Species composition, quantity, coverage, density, frequency, height and the like of undergrowth plantations of eight forest plantations on the waste piles in the top of western waste dump in Fushun City were investigated. Community diversity of forest under various species of forest. The results showed that the composition of natural plant communities under the plantation was mainly Asteraceae, Daucus, Chenopodiaceae. Compared with the bare land recovered from natural restoration, the number of plants in plantations of five forest types increased, and the number of plant species in one plantation reduced. The number of plant species in plantations increased in three forest types and that in two plantations The number of plants under the reduction. The plantarum plantation α diversity index and artificial pure forest were higher than mixed forest. In the site conditions, should focus on creating acacia, elm, Amorpha fruticosa, Caragana forest, and the use of pure forest-based, Qiao and shrubs, shrubs and grasses, supplemented by the auxiliary configuration.
