在“四化”建设中,人为水土流失的类型主要有山原区筑路造成的水土流失;开矿和采石造成的水土流失;兴修水利水电工程,乱弃沙石废土造成的水土流失;山原区建厂盖楼等基建工程和修建民房造成的水土流失;城乡工业企业排放大量粉尘、废渣、污染水源,加剧水土流失;毁林毁草开荒,陡坡开荒,造成人为水土流失;广种薄收、顺坡耕种、经济林垦复等旧的生产习惯,加速了水土流失;山原区居民发展木耳、天麻等副业生产,破坏了植被,加重了水土流失;城市垃圾、炉灰乱堆乱倒造成的水土流失。这9种类型,随着建设的蓬勃发展,有日益严重的趋势。
In the construction of “four modernizations”, the types of man-made water and soil erosion mainly include soil and water loss caused by road construction in mountainous areas; water and soil loss caused by mining and quarrying; construction of water conservancy and hydropower projects, soil erosion caused by indiscriminate disposal of gravelly wastes; The construction of factory buildings and other infrastructure projects and the construction of civil housing caused by soil erosion; urban and rural industrial enterprises emit large amounts of dust, waste, pollution of water sources, aggravating soil erosion; deforestation reclamation, steep slope pioneers, resulting in man-made soil erosion; Cultivation, economic forest reclamation and other old production practices, accelerated soil erosion; inhabitants of mountain area development fungus, gastrodia and other sideline production, destruction of vegetation, aggravating soil erosion; urban garbage, dust and disorderly caused by soil erosion. These nine types, with the booming construction, there is a growing trend.
