| 中文摘要: |
| 矿产资源开发造成土地资源和生态环境破坏，甚至影响区域经济可持续发展。我国矿区土地复垦，特别是土壤改良已成为生态修复重要组成部分。由于矿区废弃物堆场等复垦土地的土壤结构和肥力较差，土壤改良成为矿区土地复垦的核心问题。本文概述矿区复垦地土壤改良的重要性，根据国内外矿区土壤改良现状，结合我国矿区复垦地土壤特征，深入分析矿区土壤改良原理及技术，并根据矿区土壤改良研究和应用中存在的问题，结合矿区生态修复的绿色、稳定和可持续发展导向，提出我国矿区土壤改良的发展方向，旨在为今后矿区复垦地土壤改良与生态修复提供参考和借鉴。 |
| 英文摘要: |
| The exploitation of mineral resources leads to the destruction of land resources, the ecological environment, and even affects the sustainable development of the regional economy. Land reclamation, especially soil amelioration, has become an important part of ecological restoration in mining areas in China. Soil amelioration has become the primary challenge of land reclamation in mining areas because of the poor soil structure and fertility of the reclaimed land, as observed in waste storage yards. This highlights the importance of soil amelioration in mine land reclamation. The amelioration principles and techniques were comprehensively analyzed based on the soil amelioration status of mining areas in China and abroad as well as on the basis of the characteristics of soil in reclaimed mining land in China. According to the existing problems in the research and application of soil amelioration, combined with the green, stable, and sustainable development orientation of mine ecological restoration the development direction of soil amelioration in mining area was put forward. This provides reference for soil improvement and ecological restoration of mining reclaimed land in the future. |
