Urbanization and Landscape Dynamics
Dr. Weiqi Zhou is a Professor in the State Key Laboratory of Urban and Regional Ecology, Research Center for Eco-Environmental Sciences, Chinese Academy of Sciences. Dr. Zhou got his Ph.D. from the University of Vermont. Before he joins the Research Center for Eco-Environmental Sciences, he was a postdoctor fellow at the University of California, Davis. Dr. Zhou is broadly interested in urban and landscape ecology with respect to spatial heterogeneity of the landscape. He integrates field observations, remote sensing and modeling to understand the structure of urban socio-ecological systems, and its link to ecological function. He works across many disciplines including landscape ecology, urban ecology, remote sensing, and GIS, and interact with various collaborators from different fields through his involvement with various collaborative projects. The interdisciplinarity of his work has allowed him to develop innovative approaches and tools to better understanding the structure of urban socio-ecological systems, and its link to ecological function. He serves as an editorial board member for the journals Landscape Ecology, Landscape and Urban Planning, and Ecosystem Health and Sustainability.
Research interests: Urban Ecology, Landscape ecology, Spatial Modeling, Remote Sensing and Geographical Information Sciences.

Increasing impact of urban fine particles (PM2.5) on areas surrounding Chinese cities
HAN Lijian , ZHOU Weiqi*, LI Weifeng
The negative impacts of rapid urbanization in developing countries have led to a deterioration in urban air quality, which brings increasing negative impact to its surrounding areas (e.g. in China). However, to date there has been rare quantitative estimation of the urban air pollution toits surrounding areas in China. We thus evaluated the impact of air pollution on the surrounding environment under rapid urbanization in Chinese prefectures during 1999 – 2011. We found that:(1) the urban environment generated increasing negative impact on the surrounding areas, and the PM2.5 concentration difference between urban and rural areas was particularly high in large cities.(2) Nearly half of the Chinese prefectures (156 out of 350) showed increased impact of urban PM2.5 pollution on its surrounding areas. Those prefectures were mainly located along two belts: one from northeast China to Sichuan province, the other from Shanghai to Guangxi province. Our study demonstrates the deterioration in urban air quality and its potential impacts on its surrounding areas in China. We hope that the results presented here will encourage different approaches tourbanization to mitigate the negative impact caused by urban air pollution, both in China and other rapidly developing countries.
Spatial pattern of trends of difference in PM2.5 concentration between urban and rural areas from 1999 to 2011.
