小流域内土地的合理利用不仅关系到当地生产的发展,也关系到水土保持、植被恢复等环境建设。坡面治理工程是水土保持最为关键的工程措施之一,它的实施效果直接影响到整个小流域的水土保持、水利工程建设以及生态环境改善等多方面。以西吉县聂家河小流域卫星遥感图像为信息源,结合地面调查,获取土地利用的现状图,利用GIS对小流域坡面的土地利用情况进行指导,最终将形成有效的水土流失综合防护体系,达到保护、改良和合理利用水土资源,实现生态效益、经济效益和社会效益的协调统一。
The rational utilization of land in small watershed not only relates to the development of local production, but also to the environmental construction such as soil and water conservation and vegetation restoration. Slope treatment project is one of the most important engineering measures for soil and water conservation. Its implementation effect directly affects many aspects such as soil and water conservation, water conservancy construction and ecological environment improvement in the small watershed. Taking the Niejiahe small watershed satellite remote sensing image in Xiji County as the information source and combining with the ground investigation to obtain the current situation map of the land use, using GIS to guide the land utilization in the small watershed slope will eventually form an effective comprehensive protection system of soil and water loss So as to protect, improve and make rational use of water and soil resources so as to achieve the harmonization of ecological benefits, economic benefits and social benefits.
