Degradation of vegetation cover and expansion of barren land are remained the leading environmental problem at global *** surface temperature(LST),Normalized Difference Vegetation Index(NDVI),Normalized Difference Barren Index(ndbai),and Modified Normalized Difference Water Index(MNDWI)were used to quantify the changing relationships using correlation *** study attempted to analyze the relationship between LST and NDVI,ndbai,and MNDWI using Geospatial technologies in Gida Kiremu,Limu,and Amuru districts in Western *** indices were estimated by using thermal bands and multispectral bands from Landsat TM 1990,Landsat ETM+2003,and Landsat OLI/TIRS *** correlation of LST with NDVI,ndbai and MNDWI were analyzed by using scatter ***,the ndbai was positive correlation with LST(R 2=0.96).However,NDVI and MNDWI were substantially negative relationship with LST(R 2=0.99,0.95),*** result shows that,LST was increased by 5℃due to decline of vegetation cover and increasing of bare land over the study ***,our result recommended that,decision-makers and environmental analysts should give attention on the importance of vegetation cover,water bodies and wetland in climate change mitigation,particularly,LST in the study area.

This case study evaluates the seasonal variability of the Pearson's linear correlation coefficient of land surface temperature(LST)with some spectral indices like NDVI,NDWI,NDBI,and ndbai by using a series of Landsat images for 1991-92,1995-96,1999-00,2004-05,2009-10,2014-15,and *** results from the average correlation of the entire period of all-season show that the LST builds a positive correlation with NDBI(0.71)and ndbai(0.52)while it builds a negative correlation with NDVI(-0.44).The LST-NDWI correlation is *** best correlation is noticed in the post-monsoon period,while the least correlation is observed in the winter *** study can support the environmental planning to build a sustainable city under a similar environment.

Modeling and Characterization of Vegetation, Aquatic and Mineral Surfaces Using the Theory of Plausible and Paradoxical Reasoning from Satellite Images: Case of the Toumodi-Yamoussoukro-Tiébissou Zone in V Baoulé(Côte d’Ivoire)

In this paper, the theory of plausible and paradoxical reasoning of Dezert- Smarandache (DSmT) is used to take into account the paradoxical charac-ter through the intersections of vegetation, aquatic and mineral surfaces. In order to do this, we developed a classification model of pixels by aggregating information using the DSmT theory based on the PCR5 rule using the ∩NDVI, ∩MNDWI and ∩ndbai spectral indices obtained from the ASTER satellite images. On the qualitative level, the model produced three simple classes for certain knowledge (E, V, M) and eight composite classes including two union classes characterizing partial ignorance ({E,V}, {M,V}) and six classes of intersection of which three classes of simple intersection (E∩V, M∩V, E∩M) and three classes of composite intersection (E∩{M,V}, M∩{E,V}, V∩{E,M}), which represent paradoxes. This model was validated with an average rate of 93.34% for the well-classified pixels and a compliance rate of the entities in the field of 96.37%. Thus, the model 1 retained provides 84.98% for the simple classes against 15.02% for the composite classes.

城市热岛效应的增强是近年来学者们研究的突出的城市环境问题,也是全球气候变暖的一个重要的因素。本文以吉林省的省会——长春市为研究区域,利用1999年的landsat ETM数据与2007的landsat ETM数据的热红外波段反演出地表的亮度温度来代替地表真实温度,并使用计算出的NDVI,NDWI,NDBI与ndbai参数对其进行土地覆盖的分类,进而分析长春市热岛效应的空间分布状态以及其与不同地表类型之间的相互作用关系。
