Interspecific Association of Dominant Species Analysis of Different Slope Types in Mining Area, Beijing

Interspecific Association of Dominant Species Analysis of Different Slope Types in Mining Area, Beijing.

Water and soil loss due to the mining activities make extremely serious ecological degradation. Vegetation restoration is a vital solution to the construction of ecosystem. However, vegetation recovery is a slow process, thus, it is crucial significant to master the distribution characteristics of vegetation and interspecific association of dominant species in different types of slopes. Compared with rocky and soilrocky slopes, soil slopes had the highest vegetation diversity indexes, in which the interspecific association of dominant species was the closest. In general, the vegetation restoration in soilrocky slopes was more efficient than that in the rocky slopes. Engineering measure, as a method of speeding up the succession process, showed a good effect during the early stage of vegetation restoration. As the succession process continued, interspecific competition got increasingly fierce so that the mid-term vegetation restoration had gained little improvement. At the later stage, the restoration effect in slopes which adopted engineering measures was superior to those in natural restoration, and the community characteristics of vegetation in these slopes had more similarities to the native vegetation’s. Our experiment results would contribute to deepening the understanding of interspecific relationships in different site conditions and building a more stable ecosystem.
