河西走廊盐渍化沙区综合治理模式研究

Study on Integrated Control Model of Alkaline-Saline Desert Area in Hexi Corridor

针对河西盐渍化沙区的特点,在沙区采用沙障固定流沙、封沙育林育草、营造固沙阻沙林、建立防护林带的固、封、阻、带结合的沙区治理模式,在盐渍化区采用物理改良措施、种植耐盐植物生物改良措施、发展畜牧养地改碱的改、种、养结合的盐渍化土地治理模式,使沙区盐渍化土地综合治理取得显著的生态、经济效益。

According to the character of saline-land of desert area of Hexi Corridor, a control desertification model of integrated fixing, closing, defending was made up by method of fixed moving sand by sandy barrier, closed for raising vegetation, making up defending belt and establishing wind break belt. In saline land, an improving saline- land model of developing, cropping and bred was raised by physical improved method, cultivated saline-resistant plant and breeding livestock for fertilizing land. By above mentions, an ecological and economical benefit was obvi- ously taken on integrated developing saline land of desert zone.
