摘要
辽宁省黑土区位于我国东北黑土区的南部,总面积约1.23×105km2,其中水土流失面积3.33×104km2,占辽宁省黑土区总面积的26.99%。严重的水土流失造成该区耕地面积减少,土地生产力下降;河床抬高,水库淤积;环境污染严重;灾害频繁,损失加重。依据辽宁省黑土区水土流失特点,提出了相应的水土流失防治对策。
The chernozem region of Liaoning Province covers the southern part of the chernozem region in northeast China. The Liaoning chernozem area covers 123 200 km^2. In this region, land affected by soil erosion covers 33 300 km^2, or about 27% of the total land area. Soil erosion in the region has caused severe problems, such as cultivated land area reduction, land productivity decline, river bed and reservoir aggradations, environment pollution and frequent drought and flood. Some strategies for ecological construction to prevent water and soil loss are put forward based on the physical conditions of the region.
