中文摘要：

以RS、GIS为技术支撑,从景观要素斑块特征、异质性特征、破碎化特征及其空间相互关系特征对震后北川县苏保河小流域的景观格局进行了分析,旨在为小流域灾后生态恢复与景观设计以及进一步防范次生灾害提供理论依据.结果表明：流域原始景观类型仍占主导位置,但空间形态区域不规则化加剧;地质灾害产生的微地貌景观类型具有较高的空间异质性与破碎化,加剧了流域景观的不稳定性;人为干扰强烈区域及滑坡体中部沟道及滑坡后壁等区域景观空间相互关系较为复杂.

英文摘要：

In order to provide theoretical basis for ecological recovery, landscape design and further precaution of secondary disaster, the authors analyzed the landscape spatial pattern characteristics in Subaohe catchment, based on the RS and GIS technical support. In the present paper, 4 kinds of spatial pattern characteristics were applied, including the patch characteristic, the heterogeneity characteristic, the fragmentation characteristic and the spatial correlation characteristic. The results showed that： the original landscape types were still dominant, but the spatial pattern was being more irregular. Micro geomorphologic landscape types produced by geological hazards had a higher degree of spatial heterogeneity and fragmentation, which intensified the instability of the landscape pattern. Furthermore, the interaction relationship of the landscape which belonged to the human disturbance area and the center part of landslide is more complicated than other areas.
