Study on evaluation of limiting factors in artificial vegetation restoration of abandoned quarry

The fundamental principle of limiting factors in artificial vegetation restoration of abandoned quarry was discussed in this paper.Comprehensive assessment index system in artificial vegetation restoration of abandoned quarry is set up.With the help of Analytical Hierarchy Process(AHP),a comprehensive assessment artificial vegetation restoration of abandoned quarry has been made.The fundamental theory and method for comprehensive assessment of limiting factors in ecological restoration of abandoned quarry,using the Analytical Hierarchy Process(AHP) was introduced.The weight of each index is calculated by AHP.The results show that the most important species of artificial vegetation restoration is soil effectual depth.And then is soil organism.Other species ordinal is gradient,annual rainfall,soil quality,soil moisture,soil destroy extent,and soil hardness,irrigational condition,reclaim difficulty, soil pH.
