Spatial Correlation Between Remote Sensing Ecological Index and Geological Formation in Yudu County, Southern Jiangxi Province

Abstract
The geological formation is the basis of ecological environment, and the surface information is the direct expression of ecological environment. It is of great significance to study the spatial relationship between geological formation and surface information for understanding and evaluating the regional ecological environment quality. In this paper, the remote sensing ecological index (RSEI) was extracted from the three phase remote sensing images of Yudu County, southern Jiangxi Province, and Moran’s I method was used to analyze the spatial autocorrelation of RSEI. Meanwhile, the information entropy was introduced to study the spatial correlation between geological formations and RSEI. Finally, the RSEI changes in various geological formations were analyzed in detail. The results show both significant spatial autocorrelation between RSEI in Yudu, and certain spatial correlation between geological formation and RSEI. The RSEI of Mesozoic red clastic formation, Quaternary loose accumulation formation, Neoproterozoic metamorphic clastic rock formation, Late Paleozoic clastic formation and Early Paleozoic metamorphic clastic formation are less stable and prone to change. The RSEI of Late Jurassic granite formation, Nanhuaian metamorphic rock formation and Late Paleozoic carbonate formation have good stability without change basically during the three periods. -
