以 RS和 GIS技术为支撑，利用修正的土壤流失方程(RUSLE)定量评估锦州市2010年水土流失量和土壤侵蚀强度，并对锦州市水土流失空间分布特征进行分析。结果表明，锦州市2010年土壤侵蚀面积为7284.87 km2，占锦州市总面积的70.72％，平均土壤侵蚀模数为18.27 t/（hm2·年），属于轻度侵蚀；15°～25°和6°～15°2个坡度带是研究区土壤侵蚀的主要发生区域。锦州市土壤侵蚀主要发生在农村居民点和旱地2种土地类型，二者的侵蚀量占锦州市2010年总侵蚀量的60.97％。未来应加大对这2种土地类型的治理力度，将其列为水土保持重点治理对象。该研究可为政府制定水土保持的相关政策提供科学依据。

Supported by RS technology and GIS technology, the amount of soil loss and soil erosion intensity in Jinzhou City in 2010 were quantitatively evaluated by the modified RUSLE model. The characteristics of the spatial distribution of soil loss in Jinzhou City were analyzed. The results showed that the soil erosion area of Jinzhou City in 2010 was 7 284.87 km2, accounting for 70.72% of the total area of Jinzhou City. The average soil erosion modulus was 18.27 t/(hm2·a), belonging to mild erosion. Two slope belts of 15°-25° and 6°-15° were the main soil erosion re-gions in Jinzhou City. Soil erosion in Jinzhou City was mainly concentrated in the rural residential land and the dry land, and the soil erosion amount of these two land types accounted for 60.97%of the total soil erosion amount in Jinzhou City in 2010. It was suggested that the treatment of these two land types should be strengthened and be main treatment object for soil and water conservation in future. The research could provide scientific basis for the governments to make policies about soil loss.
