Ecosystem stability evaluation of different vegetation modes in mining wasteland
A case study of coal-mining wasteland in Fuxin, adopting the method of experts evaluation system, this study determined significant indicators of vegetation growth factors, soil improvement factors and vegetation dust-detaining volume factors to build ecosystem stability evaluation index system. Based on the evaluation, this study determined the best vegetation mode of ecological reconstruction in mining wasteland. The results show that ecosystem stability in mine is closely related with vegetation coverage. The larger the vegetation coverage, the better the ecosystem stability. The ecosystem stability of managed woodland mode and artificial cover-soil mode is better than natural recovery. Diversity of mixed planting mode is better than single mode. The ecosystem stability of different vegetation modes is: mixed forest-grass>torch forest-grass>locust forest-grass>various forest-grass>white elm forest-grass>grassland.
