    Abstract:

    [Objective] The restoration of soil and plant communities in a mining area after the implementation of ecological restoration measures was investigated in order to provide a basis for the evaluation of restoration measures in the mining area.[Methods] The study was conducted in the gold mine ecological restoration area at Ungulated Wildlife Nature Reserve in the Kalamaili Mountain of Xinjiang Wei Autonomous Region. The vegetation characteristics, plant community diversity, and soil physical and chemical properties were investigated and analyzed through sampling methods and laboratory experiments.[Results] Soil pH value, electrical conductivity, organic matter, total nitrogen, and total potassium in the gold mine ecological restoration area were generally lower than in the primary control area. There were fewer plant species, and the Chenopodiaceae plants from human sowing were dominant. The plant community diversity index was low and was closely related to the diversity index in the native control area. The plant community was mainly affected by the contents of soil organic matter, available phosphorus, and rapidly available potassium.[Conclusion] The soil physical and chemical properties and plant communities of Qinghe Dashagou and Fuyun Dashagou improved significantly after the ecological restoration measures, and the restoration effect was significant. Due to the short time available for recovery observations in this study, there were few plant species, low community stability, and generally low content of soil physical and chemical properties at all gold recovery areas. Therefore, these areas require still more time to recover.
