东北黑土区地域界定及其水土保持区划探析

Defining of Chernozem Area and Zoning of Soil and Water Conservation in Northeastern China

关于东北黑土区的地域界定长期以来众说纷纭,莫衷一是。而这一概念的悬疑又直接影响到《东北黑土区水土流失防治工程》的地理界定和措施选取,从土壤、地貌和经济结构三个角度论述了广义东北黑土区的地域范围,并结合该区水土保持区划成果对黑土区水土保持生态建设提出了建设性建议。

The border of chernozem area in the Northeastern China has been discussed for a long time, but the view differed, and it would directly affect the zoning and the measure selecting in conducting 'Soil erosion prevention and control project of chernozem area in Northeastern China'. We try to expound the scale of the chernozem area in Northeastern China in a broad sense from the regional soil, geomorphology and economic structure. Some constructive suggestions on ecological construction of chernozem area are put forward in view of soil and water conservation.
