| Abstract: |
| The environment pollution and ecological destruction caused by mining wasteland have made serious
crisis to the ecologically sustainable economic development and human life. Ecological restoration is one of the important
measures to solve the ecological environment of mining areas，and the revegetation is the key to the ecological restoration
of mining wasteland. This paper summarized the changes of soil physical properties（water-holding，soil bulk density，
and porosity），chemical properties（nitrogen，phosphorus and kalium），and biological properties（microbial
biomass，enzyme activities，and nematode）during the progress of vegetation restoration，aimed to elucidate the
responses of soil properties to phosphate mine wasteland. Some suggestions for further researches in this field，e g，soil
fauna as biological soil health indicator，to strengthen the responses of soil fauna to the change of soil quality，in order
to promote the dynamic changes of soil fauna community and its relationship with soil quality vegetation after Kunyang
phosphate revegetation. |
