Landslide Susceptibility Assessment Using Conditional Analysis and Rare Events Logistics Regression: A Case-Study in the Antrodoco Area (Rieti, Italy)

Journal of Geoscience and Environment Protection 2016年第12期4卷 1-21页

作者： Vittorio Chiessi Simona Toti Valerio Vitale Geological Survey of Italy Department of Soil Institute for Environmental Protection and Research Rome Italy Directorate for Methodology and Statistical Process Design National Institute of Statistics Rome Italy Directorate for Environmental and Territorial Statistics National Institute of Statistics Rome Italy

This paper discusses some methodological aspects for the production of susceptibility maps of slope instability developed within the CARG Project (Geological cartography of Italy at 1:50,000 scale). It describes an example of a susceptibility map in the presence of low susceptibility, using database having zero or negligible cost, with the aim to test some methodologies that can be easily reproducible to get a first estimate of the landslide susceptibility on a wide area. Two statistical approaches have been applied: the non-parametric conditional analysis and the logistic analysis for rare events. The predictive ability obtained from the two methodologies, was evaluated by the success-prediction curves for the conditional analysis, and by the Receiver Operating Characteristic curve (ROC), for the logistic model. The landslide susceptibility maps have been classified into four classes using both the Natural Breaks algorithm and the method proposed by Chung and Fabbri (2003). The paper considers the influence of these two classification methods on the quality of final results.

cartography of Air Pollution in an Industrial City in North-Eastern Algeria by Using Two Indexes： Poleotolerance Index and Atmospheric Purity Index

Journal of Life Sciences 2014年第1期8卷 95-100页

Of all the methods of studies on bio-estimation of air pollution by lichen flora, the authors cannot justify a choice of one method over another. Consultation of previous work by researchers has allowed us to compare these methods and to better understand their strengths and limitations. Under the terms of estimating the pollution, these methods are classified into three categories. Some are qualitative, quantitative and others are finally some indirect methods. The methods used to assess the overall air pollution relative value for each station studied. As part of our work, the authors have chosen a quantitative approach based on the combination of two methods. They are based on pollution indices obtained from mathematical formulas based on various parameters related to the lichen flora. They are represented by the I.P. （index poleotolerance） and the I.A.P. （index of atmospheric purity） and these two indices allowed us to map of global air pollution in the city of Skikda and petrochemical industry as well as peri-urban areas （Haddaiek, Hamadi Krouma, Hamrouche Hamoudi, Larbi Ben M＇Hidi）. The authors have identified areas of iso-pollution around different emission centers represented by the largest petrochemical area, traffic and households in urban areas of Skikda, Hamadi Krouma, Hamrouche Hamoudi and Larbi Ben M＇Hidi.

介绍了应用InSAR技术监测矿区地表沉降以及地下开采活动的原理;利用重轨差分InSAR技术获得了峰峰矿区地表ENVISAT和JERS 1的雷达形变干涉相位图;分析了在矿区地表沉降过程中ENVISATC波段和JERS 1 L波段形变干涉相位图的相干特性、相位特性以及干涉测量技术在矿区地表沉降监测中应用的可行性和局限性。实验结果表明,利用C波段和L波段雷达数据可以实施对矿区地表沉降的监测,但是C波段雷达受到空间干涉基线的限制更加严格,如果要实现对矿区地表沉降的监测,需要充分利用每个卫星回访时期的雷达数据,建立长时序的星载雷达形变干涉相位图序列,才能较好地实现矿区地表沉降监测。
