| 摘 要： | 北方土石山区现有轻度以上水土流失面积13．49万km^2,其中水蚀面积约占95％,水蚀区虽以轻度侵蚀为主,但水土流失仍然是该区主要的生态环境问题,不仅制约山区经济的发展,而且严重影响下游经济发达地区的水资源安全和生态安全,加强区域水土保持已成为区域发展的迫切要求。北方土石山区的水土保持,在新的时代背景下,应更加关注坡耕地改造、“坡林地”水土保持、“节水型”措施和生态“清洁型”小流域建设。依据自然地带性规律、区域经济发展和社会需求,北方土石山区可分为8个水土流失综合治理区,各区应当结合实际情况采取有针对性的综合治理对策。 |
| 关 键 词： | 水土流失 治理对策 北方土石山区 |

| Abstract: | There is 13.49×10 4 km2 land with soil erosion in varied degrees in rocky mountain areas of Northern China.Water erosion occupies 95% of the area and is usually under moderate level.Soil erosion is still one of the major regional environmental issues,for its restriction of regional economic development and severe affection on the water resource and ecological security of downstream areas.Soil and water conservation in this region should focus on the transformation of slopping cultivated land,soil protection on "slopping forest land",adoption of water-saving erosion control measures and promotion of ecologically "clean" watershed.The total region can be divided 8 sub-regions based on the variance of natural condition.Each sub-region should take different conservation measures discussed in the article. |
