This paper took Yancheng region as the study area to explore the relationship between landscape pattern and water quality. Land use types were obtained from the classification of the TM images, 2006. Landscape patterns characterized by land use pattern and five selected landscape metrics were extracted from buffer zones, ranging from 200 to 1500m, and used in correlation analysis against various water...
The changes of impervious surface from 1986 to 2006 and the relationship between those changes and hydrological response were studied in the Qinhuai River Basin (2631 km2), which is located in the southwest of Jiangsu Province, P. R. China. A series of Landsat imagery during that period was employed to extract impervious area using the Linear Spectral Mixture Analysis. The results showed that impervious...
The reflectance of red and near infrared bands has proved to be sensitive to water depth. This paper takes four sections in Jiangsu Coastal Zone as a typical study area. Different models for retrieval of water depth have been evolved based on analysis of the ETM image and field measurements of the research area. Then, water depth was computed by depth retrieval model and the accuracy of predicted...
Remote sensing can provide base information for documenting salinity change and for predicting its future evolution trend. The spatial and temporal distributions of soil salinization of Jiefangzha Irrigation Sub-district, the western part of Hetao Irrigation District of Inner Mongolia in northern China, were determined through analysis of satellite-based remote sensing images. Three Landsat TM/ETM+...
