- 摘要:
- 以南京幕府山采矿废弃地生态修复为例，探讨生态修复如何影响采矿废弃地土壤的性质。研究结果表明：生态修复在先的废弃地土壤有机质含量相对高，因修复模式不同，同一时期修复的土壤有机质含量存在差异；土壤pH值与土壤容重主要取决于修复覆盖的土壤性质，且随修复时间增加，容重降低，而修复植被的生长也影响土壤pH值与土壤容重；土壤水文效应则主要取决于覆土厚度，其次是土壤孔隙度，而土壤孔隙度与土壤容重也与修复植被有关。
- Abstract:
- Based on a case study of ecological restoration of abandoned lands in mining area of Mufu Mountain in Nanjing, the influences of ecological restoration on the soil properties of abandoned lands in mining area were analyzed. The results showed that the earlier ecologically restorated abandoned lands were, the higher soil organic matter content was; the soil organic matter contents were different at the same restoration period due to different restoration modes; soil pH and soil bulk density mainly depended on the properties of the cover soil, soil bulk density decreased with the increase of the restoration duration; and vegetation growth in abandoned lands of the mining area also affected soil pH and soil bulk density; hydrological effects of soil primarily depended on the thickness of cover soil, followed by soil porosity, and the soil porosity and soil bulk density were related to the vegetation restoration.
