The project was closely related to research theme 2 of AP N Science Agenda: Ecosystems, Biodiversity and Land Use, and had an international research team that was composed of three leading developing country scientists (China, Philippines and Vietnam). The project clearly addressed existi ng gaps in the field of global change research, which ran for 2 years and received a total funding of US$40,000 from APN. We had built an international research team, a database and a project website at http://apn.ueplab.cn or http://www.usplab.cn/apn. In Mar.11-14, 2008, we have trained five young scientists (China, Philippines and Vietnam) on advanced methods of remote sensing technology and GIS and urban landscape pattern analysis. On the same month, we have also trained 20 yo ung scientists and conducted a workshop meeting to conclude our work and present the project results at Nanjing University in China. We also conducted some research works on the quantifying urbanization level from the aspect of land use and connecting land use pattern with urbanization process in the three biggest cities of three developing countries and published three scientific papers. The results showed that urbanization leads to land use change and landscape pattern alteration, which responded obviously to the urbanization phases. As the urban ecosystem is a complex ecosystem, it is important to consider both landscape metrics and social-eco nomic factors in urban ecosystem studies. The sustainable problems of urban ecosystem can also be revealed using RS and GIS technology and CA model.
