Paper Abstract

Land structure and amount directly influence urban development, since it is an elementary resource for various activities in urban systems. However, land use zoning in urban system is often conducted from the view of economic and social benefits, not considering ecological benefit. Taking Nanjing city as the study area, the present paper studied land cover constitution of different land use zoning and constructed the quantitative relationship between urban ecological parameters of land surface temperature (LST) and land surface dryness (LSD) and land cover constitution. Land cover information was acquired from IKONOS data based on a decision tree method, LST was retrieved from the thermal band of Landsat ETM+ data using mono-window algorithm, and LSD was calculated from the LST/NDVI space. Analysis results showed that land cover constitutions within different land use zonings have great variations, and the relationships between ecological parameters and land cover constitution also showed a close correlation; the percent vegetated area had strong negative relationship with LST and LSD, while the percent impervious surface showed obvious positive relationship with LST and LSD. These conclusions should be considered in urban ecological environment management.
