渭北坮塬区荒草地整治技术创新、应用推广及综合效益评价

Technical innovation, application and extension and comprehensive benefit evaluation of waste grassland rehabilitation in Weibei Tableland Area

渭北坮塬区土地资源丰富,未利用地面积大,而地形复杂、生态脆弱、水源紧缺且分布不均等自然特性严重制约了土地资源的开发利用。在通过梯田修筑、水源开发利用、灌排减压等一系列技术创新,实现了渭北坮塬区荒草地大面积的开发利用。一方面服务了地区经济社会发展,保障了国家土地和粮食安全;另一方面在当地实现了良好的社会、生态和经济效益。为渭北坮塬区土地资源开发利用,生态环境建设提升,落实乡村振兴发展奠定了基础、树立了示范。

The Weibei Plateau area is rich in land resources and has a large unused area. The natural characteristics of complex terrain, fragile ecology, shortage of water resources and uneven distribution seriously restrict the development and utilization of land resources. Through a series of technological innovations, such as terrace construction, water resources development and utilization, irrigation and drainage, and decompression, a large area of waste grassland in Weibei plateau area has been developed and utilized. On the one hand, we have served the regional economic and social development, guaranteed the national land and food security. on the other hand, we have achieved good social, ecological and economic benefits in the local area. It has laid a foundation and set a model for the development and utilization of land resources, the promotion of ecological environment construction and the revitalization and development of simple countryside in Weibei plateau area.
