聊城市位于华北平原的西北部,历史上黄河多次决口、改道泛滥冲积,上游携带物质在境内决口扇形地和沙质河槽地处大量沉积。土壤质地均为沙质土,结构疏松,春季常随风飘扬滚动,雨季在地表径流的冲蚀下,水土流失和土地沙化十分严重。针对聊城市的自然环境特点、水土流失和土地沙化现状,提出了以生物措施为主、工程措施为辅,同时结合农业现代技术等综合治理的措施,因害设防,形成水土流失综合防治体系。树立人与自然和谐相处的指导思想,发挥生态的自然修复能力,加快水土流失防治速度。
Liaocheng is located in the northwestern part of the North China Plain. Historically, the Yellow River broke through many times and diverted alluvial sediments. The materials carried by the upper reaches were massively deposited in the territory of the territory of the Ordos Basin and the sandy fluvial channels. Soil texture is sandy soil, loose structure, the spring often wind and rolling, the rainy season runoff erosion, soil erosion and desertification is very serious. In view of the characteristics of natural environment, soil erosion and land desertification in Liaocheng City, we put forward biological control measures and supplemented engineering measures, combined with the comprehensive management of agricultural modern technologies and other measures, and set up a comprehensive prevention and control system for soil and water loss. Establish the guiding principle of harmonious coexistence between man and nature, give play to the ecological ability of natural restoration and speed up the prevention and control of soil and water loss.
