Title: Opportunities and Challenges for Advancing Landscape Geochemistry with Support of Geospatial Technologies
Abstract:
As
a cross-disciplinary scientific domain, landscape geochemistry interacts with
natural resources relevant subjects such as mineral exploration, agricultural
production and land use planning with considerable environmental benefits, and
provides substantially theoretical and applied supports to their utilization.
Since its establishment, a great deal of research has been conducted. However,
there are a few gaps that still remain. First, the current studies are only
limited to characterizing the spatial distribution of chemical elements and
exploring their mechanisms at landscape level and ignore the integrated
analysis using multidisciplinary approaches. Moreover, the used methods lack
the ability of revealing the relationships of landscape geochemistry with other
sciences, and the obtained knowledge is thus fragmented and isolated, and its
development has not been globally paid attention to. In this study, the
state-of-the-art regarding the applications of relatively new geospatial
technologies including fractal theory, geographic information system and remote
sensing to landscape geochemistry was reviewed and analyzed to provide deep
insights of current research and a roadmap for furthering the development of
landscape geochemistry as a cross-disciplinary discipline. The results showed
that substantial research on the applications of fractal theory, GIS and RS
technologies for analyzing the processes and data of landscape geochemistry has
been conducted by using the advantages of the geospatial technologies. However,
the great challenges still exist when the geospatial technologies were
individually utilized due to the limitations of the technologies themselves and
the complexity of landscape geochemistry. In the end, opportunities and
challenges for advancing the further studies of landscape geochemistry were
discussed in detail and new directions of studying landscape geochemistry using
multidisciplinary or integrated approaches to enhance understanding the
relationships among the relevant disciplines were suggested.
Keywords: Landscape
geochemistry; fractal theory; geographic information systems; remote sensing;
