朝阳县地处内蒙古东部科尔沁沙地的南缘,土地脊薄,生态脆弱,是全国水土流失防治的重点县之一。经过近30 a的艰苦奋斗,全县的“四荒”面积得到基本治理,但由于历史和现实的原因,坡耕地治理的速度还远远落后于“四荒”的治理速度,坡耕地治理是水土流失治理的薄弱环节与难点,严重制约了全县农村经济的发展。为解决坡耕地治理存在的问题,朝阳县从“十二五”开始,偿试“坡耕地规模化治理,梯田集约化开发利用”的路子,现已收到了较好的效果。其治理方式在流域综合治理中值得大力推广。
Chaoyang County is located in the southern edge of Horqin Sandy Land in the eastern part of Inner Mongolia. It is one of the key counties in prevention and control of soil and water loss in China. After nearly 30 years of hard work, the county’s “Four Shortages” area has been basically ruled out. However, due to historical and practical reasons, the rate of slope farmland management lags far behind that of the “Four Shortfalls” Slope farmland management is the weak link and difficult point of soil and water erosion control, seriously restricting the county’s rural economic development. In order to solve the existing problems of sloping farmland management, Chaoyang County has received good results since the “Twelfth Five-Year Plan” period and has tried its best to scale-up the sloping farmland and intensify the development and utilization of terraced fields. Its governance is worth promoting vigorously in the comprehensive management of the river basin.
