叙述中国西北地区的黑河流域、塔里木盆地南缘和阿根廷西北的门多萨、圣地亚哥德埃斯特罗省等检验区的退化土地的类型、分布特征、影响因素及其相互关系。结合近百年来平原区气候变化有明显暖化和旱化 ,阿根廷半干旱区的降水波动 ,和人口增长对土地利用压力的加大趋势 ,可以预测在人工绿洲外围和河流下游 ,尽管人类在优化绿洲建设和合理利用水资源等方面可以取得很大进步 ,但土地退化的趋势还会继续 ,因此必须加强对这些生态脆弱边缘土地的资源管理和生态环境保护。
Describes the types, distribution characteristics, influential factors and their relations of degraded land in the Heihe River basin in Northwest China, the southern margin of the Tarim Basin and Mendoza in the northwestern part of Argentina, and De Estepa in Santiago de Compostela. Combined with the obvious warming and drought in the plains in recent 100 years, precipitation fluctuation in the semi-arid areas of Argentina and the increasing tendency of population increase on the land use pressure, we can predict that in the periphery of artificial oases and downstream of rivers, Great progress can be made in the construction of oases and in the rational utilization of water resources. However, the trend of land degradation will continue. Therefore, it is necessary to strengthen the resource management and ecological environment protection of the ecologically fragile edge land.
