Taking a reclaimed ecosystem in dump of Pingshuo opencast coal mine for 20 years as the research object,the implementation effects of ecological rehabilitation technologies were analyzed including soil reconstruction,screening pioneer species,vegetation succession and changes of animal,microorganism and soil nutrient.Results showed that the particular reclamation technologies-dump surface were covered directly by loess parental material,then ripened by fertilizing,were developed in Pingshuo mine.Many vegetation configuration modes were screened with Caragana korshinsk×Robinia pseudoacacia×Pinustabulaeformis,Robinia pseudoacacia×Pinus tabulaeformis and Robinia pseudoacacia×Hippophae rhamnoides etc.With the increasing of reclamation years,wild species invaded,soil seed bank gradually formed and species diversity has increased.Moreover,vegetation communities tended to stability and animal,microbial and soil nutrient presented the increasing trend.All these changes indicated that the ecological system have entered a normal succession process.But duo to the influence of special habitat and natural objective conditions,some problems such as diseases and pests,intraspecific and interspecific moisture competition etc,have resulted in vegetation degeneration.So ecological management of plants succession needed to be study in detail.
