- Abstract:
-
The suitability assessment for the gangue mountain vegetation restoration is an appraisal to assess the suitable degree of the gangue mountain vegetation resilience. The suitability appraisal has been developed to be the foundation for study on the restoration of the gangue mountain vegetation. The study site is located in a gangue mountain of Pingdingshan, He’nan Province, which is divided into six units according to the altitudes and the solar irradiance. Seven assessment factors such as depth of soil layer, water holding capacity of soil were chosen according to the local conditions. The recovery of the vegetation was evaluated by using the principal component analysis. The results show that the main restrictions for vegetation restoration are the depth of the soil, water holding capacity of soil and the content of organic matter. The suitability scores for different regions were 2.68 for unit A1, 1.84 for unit A2, 2.97 for unit B1, 1.98 for unit B2, 3.11 for C1, 2.97 for unit C2. It can be seen that the regions with lower altitudes are much more suitable for the restoration of the vegetation compared with the regions with higher altitudes. It can also be found out that the shady side of hillock is much more suitable for the restoration of the vegetation compared to the southern aspects of the regions.
