【摘要】 锡林郭勒草原生态环境脆弱且不稳定,荒漠化分布广泛。本文以锡林郭勒草原荒漠化为研究对象,利用遥感技术、GIS技术、结合数理统计方法,分别对锡林郭勒草原加00,2005和2009年荒漠化灾害孕灾环境危险性进行了评价。结果显示:锡林郭勒草原孕灾环境危险性西部高、东部低,中度危险区面积最大;2000^2009年极低危险区、低危险区、中危险区和极高危险区都向高危险性地区转移;研究区荒漠化灾害孕灾环境危险性与荒漠化程度基本一致。更多还原

【Abstract】 Ecological environment of Xilingol grassland are fragile and unstable and the desertification are widely distributed in this area.Took Xilingol grassland desertification as the object of this study,we has carried on hazard assessment on disaster-pregnant environment of desertification in Xilingol Grassland by using remote sensing technology and GIS technology and related mathematical statistics methods.The result showed that the hazard of disaster-pregnant environment in Xilingol grassland is high in the west,low in the east and area of moderate hazard is largest Extremely low hazard areas,low hazard areas,moderate hazard areas and extremely high hazard areas have changed into high hazard areas in the study.The hazard of disaster-pregnant environment of desertification Xilingol grassland and the degree of desertification are almost the same in Xilingol更多还原
