中文摘要：

一位女士 8.0 大地震发生在四川，中国在 2008 年 5 月 12 日(此后叫了 5.12 地震) ，然后大碎片流动在 2008 年 8 月 13 日发生在 Mianzhu 县的地震点击 Qingping 镇区(此后叫了 8.13 碎片流动) 。在陆地使用的变化上的二灾难的影响被使用高分辨率的天线相片和在 5.12 地震和 8.13 碎片流动前后拿的卫星遥感图象分析，合适的构造土地的选择被听说从再定居区域并且通过地调查并且与土地的选择的经验和课与 RS 和 GIS 在联合使用转移模型和分析模型学习。结果证明生态的环境上的 5.12 地震的影响比 8.13 碎片流动的远大；在地震以后在人口和陆地之间有更突出的冲突。为灾难以后的重建的地点不应该在灾难容易的区域或在面对溪谷的区域。为在 I-1I-5 低危险的地区的解决建设的合适的土地是为灾难以后的重建的最佳的解决区域。

英文摘要：

A Ms 8.0 large earthquake occurred in Sichuan,China on May 12,2008（hereafter called 5.12 Earthquake）,and then a large debris flow happened in the quake-hit Qingping Township of Mianzhu county on August 13,2008（hereafter called 8.13 Debris Flow）.The influence of two disasters on the changes in land use were analyzed by using highresolution aerial photos and satellite remote sensing images taken before and after the 5.12 Earthquake and 8.13 Debris Flow,the selection of suitable construction land were studied by learning experiences and lessons from the selection of resettlement areas and through field surveys and with land use transfer model and analytical model in combination with RS and GIS.The results showed that the influence of the 5.12 Earthquake on ecological environment was far greater than that of the 8.13 Debris Flow;there were more salient conflicts between population and land after the earthquake.Sites for post-disaster reconstruction should not be in disaster-prone areas or in gully-facing areas.Suitable land for settlement construction in I-1~I-5 low-hazard zones is optimal settlement areas for post-disaster reconstruction.
