Ziyue Chen BSc MSc

PhD Candidate

Ziyue's current research focuses on adopting Airborne Lidar to model urban landscape ecology

Biography

Ziyue's first degree was in Geographic Information System. He finished his fourth year bachelor project on the application of adaptive sampling in allocation of housing price monitoring sites. This research was included in a governmental project, so it not only encouraged his interest in GIS, but also developed his ability and will to find research topics in social issues.

He continued his research in the applications of GIS and Remote Sensing during his master's study and extended his research fields to landscape, housing and regional planning. His master thesis was research on land use strategy based on spatial analysis, aiming to provide decision support for planners and managers.

His current research mainly focuses on modelling urban landscape ecology and understanding the role of vegetation in urban system using Airborne Lidar, Remote Sensing and GIS.

Research

Vegetation in urban area is playing an indispensable role in our daily lives in terms of air quality, local climate, aesthetics, recreation, economics and ecology. As a result, more and more research emphasis has been put on analyzing the role of urban vegetation and establishing a green urban system. To achieve this objective, it is important to gain an incisive understanding of urban landscape composition, patterns and inner mechanisms from the perspective of landscape ecology.

Airborne Lidar (Light detection and ranging) is an emerging technique that obtains the height information of surface target by calculating time spent in signal reflection. Accompanying with the GPS fixture in the system, Lidar can provide researchers with data sources of high resolution and accuracy in both horizontal and vertical levels. . As a result, Lidar data will not only be an excellent option for landscape ecology research, it will be an evolutional tool for this discipline because Lidar makes it possible to view landscape structure in a 3 dimensional perspective, which will overcome the disadvantages from traditional 2D landscape model.

By adopting methods in Remote Sensing image processing and improving them according to the characteristics of Airborne Lidar, this research will conduct landscape classification in urban areas and then establish 3D patch-based landscape model. Based on this model, landscape patterns, especially spatial structure of urban vegetation will be analyzed, evaluated and optimised whilst Field work will be carried out to test the accuracy of classification and modelling.
