摘要
黄土高原是我国水土流失最为严重、生态环境极为脆弱的地区之一,生态环境建设对区域的发展极为重要。白银市区位于甘肃省中部,属典型的黄土高原矿农交错区。恶劣的自然环境和以工业为主体的强烈的人类经济社会活动共同作用,使白银市区产生了诸如水土流失日趋严重、土地退化面积不断扩大、水资源进一步短缺和天然植被遭到人为破坏等生态环境问题。通过对白银市区生态退化的现状及原因的分析,根据恢复生态学、可持续发展原理和生态经济学理论,根据白银市区实际情况,提出了白银市区生态恢复的原则和对策。
Loess Plateau is one of the most serious water and soil loss areas in China. The environment is very fragile. Located in middle of Gansu Province, Baiyin City is a typical ioint area of mining and agriculture in Loess Plateau. Owing to fragile environment and strong human activities, many kinds of environmental problems summarized as land degradation, water and soil erosion, shortage of water resource and vegetation degeneracy occur in recent years. The causes and current conditions of environmental degradation in Baiyin area are analyzed. Based on the principles of restoration ecology, sustainable development and ecological economics, the authors give out some measurements for environmental restoration in this area.
