| 摘 要： | 土地退化防治具有重要的战略意义.分析和正确认识当前的土地退化状况,将有利于更好地开展土地退化防治工作.本文通过分析比较得出,陕西省土地退化类型主要以风蚀、水蚀、盐渍化和土壤污染为主.土地退化的演变过程大体分为3个阶段,即生态环境破坏大于建设阶段,退化土地恢复建设阶段和生态环境综合治理阶段.从1999年和2004年的监测数据看出,陕西省的土地退化状况得到了一定的改善.结合陕西省的自然地理和人文环境特点,对土地退化的形成原因进行分析和探讨,并初步预测了陕西省土地退化可能的变化趋势. |

| Abstract: | Through comparative study,land degradation was categorized by wind erosion,water erosion,salinization and pollution.Evolution of land degradation was divided into three stages: ecological damage overriding the construction,restoration of degraded land and integrated approach to ecological restoration.The data monitored showed the improvement in the treatment of land degradation.Some development trend in land degradation was predicated in combination with the factor analyses causing land degradation from geo... |
