  • I completed my M.S in Cartography and Geography Information System in University of Chinese Academy of Sciences in 2011, and B.E. in Photogrammetry and Remote Sensing in Wuhan University in 2008. During the seven years of my study in the university and graduate school, I systematically learnt GIS and other relevant fields, including Remote Sensing (RS) and GPS. After graduation, I participated in many conservation projects relevant with GIS, from which I gained rich experience about creating maps and GIS training. ArcGIS 9.2 & 9.3 is the most frequently-used GIS software for me. I began to learn the software to vectorize maps and do spatial data analysis in 2007, MIST 2.3.4.5 & SMART 1.0 is the second most frequently-used GIS software for me, which is develped based on MapObjects of ESRI and specifically designed for wildlife protection, management, data collection and analysis.

    Secondly, I have learnt extending ArcGIS and  MapInfo with my own modules created in Visual Basic and C#.  I developed two GIS systems based on ArcObjects and Visual Basic for Application (VBA) respectively with the function of adding and deleting layers, displaying, zooming and moving maps, as well as querying. I also developed advanced GIS systems with more functions like creating thematic maps, measuring, symbol selection and statistics based on MapX and MapObjects.

    I participated in Changtang monitoring capacity building project held from August to September, 2012, and was responsible for training 22 forestry bureau stuff from Ali Prefecture and Nagqu prefecture (two prefectures of Tibet in Southeastern China) how to use ArcGIS to analyse monitoring data and create maps. I also gave presentation to introduce GIS to WCS stuff and trained them how to use ArcGIS to create maps. I trained forestry official bureau stuff in Hunchun how to apply MIST 2.3.4.5 in their conservation work to manage and analyze wildlife and human activity data.

    The project I plan to bring to the training is the survey of Amur tiger habitat degradation factors in Hunchun, which may be held from June to September, 2013. The purpose of the survey is to understand the status and trend of human disturbance in Hunchun through investigating landuse in Hunchun, especially pasture,  farmland, mine, Ginseng land and frog farm. Firstly, I need to participate in the work of designing the survey. I need to provide information about the places which might bear human disturbance through analyzing various data resources: (1) Human activity data gained through monitoring work in the past. Since 2008, rangers of HNR began to record human activity information. The information will be used for determining the potential sites that bear human disturbance. (2) Remote sensing images. Landsat TM/ETM images are now available in the Internet free of charge. However, the spatial resolution of these images is 30m and may not be enough for identifying human disturbance areas. Thus I might need to use Google Earth to find the possible areas. Secondly, I need to establish a model to analyze human disturbance trend and identify tiger habitats in Hunchun. Because the price of cattle increases sharply in recent years, farmers raise more cattle than before, which occupy larger areas and destroy forests in tiger habitats. Meanwhile, more fences are built up for breeding these cattle, which reduce the areas of tiger habitats. Thus a model should be built to analyze pastures and other landuse area, to determine habitat degradation status and trend in Hunchun.
