坡耕地是指分布在山坡上,地面平整度差、跑水跑肥跑土突出、作物产量低的旱地,主要特征是“坡地”的概念,一般是指6度~25度之间的地貌类型(开垦后多称为坡耕地)。坡耕地的存在严重制约了旱地作物产量的大幅度提高。关于坡地的开发问题历来就存在着巨大的争议。又有人认为“坡地”尤其是15度(大于25度常称为陡坡耕地)以上的坡地只能以造林解决生态环境 Slope cultivated land refers to the distribution on the slopes, the ground surface roughness is poor, run-off run-off soil outstanding, crop yield is low, the main feature is “slope ” concept, generally refers to between 6 degrees to 25 degrees Landform type (after reclaiming more known as sloping land). The existence of sloping arable land has seriously hampered the substantial increase of dry land crop yield. There has always been a huge controversy over the development of slopes. Some people think that “slopes”, especially 15 degrees (more than 25 degrees often referred to as steep arable land) above the slope can only afforestation to solve the ecological environment
