生态学原理在土地复垦中的应用
Applications of ecological principle on land reclamation
摘要
Abstract
To demonstrate the application of ecological principle on land reclamation in a mining area, this study presents a study on dump reclamation at Heidaigou open pit coal mine. Based on ecological principle, to improve soil structure and soil fertility, some leguminous plants are selected as pioneer species according to the site conditions and soil conditions. With the improvement of soil fertility, some strong tolerant shrubs and trees are gradually planted to form a stereoscopic landscape consisting of grass, shrubs and tree. Therefore, the biological and environmental co-evolution is strengthened to stabilize the whole reclaimed structure of the ecological system and gradually develop to a highest ecological evolution stage. The comparisons of soil erosion situation, vegetation root growth and vegetation covers before and after dump reclamation show that the land reclamation should follow the ecological principle.关键词
