摘要
利用3S技术和景观生态学原理,以小流域为单元对秦皇岛市土地利用结构和土壤侵蚀等级类型进行空间分析,得出了不同土地利用结构所占面积和不同土壤侵蚀类型所占面积及分布小流域,并详细分析了秦皇岛市土壤侵蚀的主要影响因子和不同土地利用结构侵蚀现状。
Taking watershed as a unit, soil landscape structure and soil erosion types of Qinhuangdao city were analyzed in spatial pattern by 3S technology and landscape ecology, counting the area of different soil landscape structure and different soil erosion types, distributing them to watershed, analyzing particularly influence factors of erosion and erosion of different soil landscape structures.
