山西矿区退化土地复垦途径的试验研究

在重建矿区生态系统的研究中,围绕矿区退化土地的复垦种植问题,从适生物种筛选、种植方式选择以及对退化土地培肥熟化效果等方面进行了试验研究,取得了较好的效果。据试验结果和当地自然生态环境现状认为,把绿肥牧草,特别是豆科牧草作为矿区各类型退化土地复垦的先锋植物,是快速培肥熟化、恢复保护矿区土地资源和重建矿区生态环境的一项有效途径。

AN EXPERIMENTAL STUDY OF THE RECLAMATION WAYS OF THEDETERIORATED LAND IN THE MINING AREA OF SHANXI

n the study of reestablishing the ecological system of the mining area, we selected the plant strains fit for growing, compared different growing methods, and cultivated the deteriorated land with manure. According to the experimental results and the na tural ecological environment conditions, we think that planting the green manure crop legume is an effective way for quickly restoring the soil fertility, protecting the land resource of the mining area, and reestablishing the ecological environment of the mining area.
