六盘山预防保护区水土保持动态监测

Dynamic Monitoring of Soil and Water Conservation of Liupan Mountain Protection Region

六盘山预防保护区属于国家公告的水土流失重点预防保护区,而该地区自2006年以来从未开展过任何水土保持监测工作。该文通过外业调查手段,利用"3S"技术为核心的遥感监测技术,确定六盘山预防保护区的范围和界线,然后在新确定的保护区以县为单位对土地利用、植被盖度和预防保护区分区等情况进行调查。对调查结果进行分析并提出相关建议,为该区域动态监测提供可靠依据,同时也为国家实施新一轮水土流失监测与公告项目奠定理论基础。

As a national key prevention reserve of soil and water loss,Liupan mountain region has never been monitored on soil and water conservation since 2006. By use of external investigation and dynamic monitoring for the first time based on '3S' techniques,the region scope and boundary,situation of land use,condition of vegetation cover and protection partition were investigated. According to the investigation results and corresponding analysis,some advice were given for the dynamic monitoring in this area. And a solid theoretical basis was shown for the complementing of a new monitoring on soil and water loss and corresponding announcements.
