| Abstract: | A geo-environment vulnerability evaluation for urban land-use planning is critical for sustainable urban development. Geographic information systems are capable of managing large amounts of spatially related information and provide an ability to integrate multiple layers of information and derive additional information. Taking Lanzhou city as an example, this paper presents a case study of geo-environmental vulnerability evaluation for urban land-use planning aided by GIS. According to appropriately measured and weighed factors, a vulnerability map for Lanzhou city is developed using an algorithm that combined factors in weighed linear combinations. It is demonstrated that the GIS methodology has high functionality for urban geo-environmental vulnerability evaluation. |
