I am a research assistant in the Institute of Geographical Sciences and Natural Resources Research, Chinese Academy of Sciences. My research field includes the application of RS and GIS in the ecosystem monitoring and assessment. Recently, land cover and its dynamic mapping, ecosystem function and ecosystem serverices mapping and ecosystem services flow modelling, and wetland monitoring are listed in my task note. I am familar with some RS and GIS software, such as Erdas, Arcgis. Some feature of GRASS are attractive to me, eg. object-based classification and its spatial modelling capacity and potentials. I want to be one of the participants in GRASS application and development.
