Biography
Hailing from Cheng Du, one of the most beautiful cities in China, Ligang Dao gained an MSc in Environmental Sciences from Sichuan University in 2004. He worked in Sichuan Grassland Science Academy since 2004, and have participated in several projects, such as “Using GIS and VB to Establish the Database of Grassland Recourses in Hong Yuan County”, “Recovery and Construction of Sandy and Degrade Grasslands in Northwest Sichuan Province” etc.
Research interests
Ligang Dao is very interested in using ecological knowledge, GIS, and mathematics to analyses environmental pollution problems, particularly heavy metal pollutants in urban soils.
Current research
“Characterizing variation of heavy metal pollution in urban soils”
It is important to realise that the soil is both a source of metals and also a recipients of metal contaminants from various sources, with strong variation in both horizontal and vertical directions. In my coming three years’ research, soils will be sampled from chosen typical areas such as a residential park, an industrial site, a road side land, and a reclaimed rubbish dumping site, and heavy metal concentrations will be measured. Advanced spatial analyses, including hotspots analyses, spatial structure analyses, spatial interpolation and hazard assessment under a GIS environment will be carried out to characterise the variation and to aid to develop a hazard assessment framework for heavy metal pollution in urban soils.
At present, the main works are site selection and sampling design, which are vital to my research. But equally important, and sometimes even more so, is to improve my oral and written English.
