摘要

城市覆盖监测对于规划人员、管理人员、政府和非政府组织优化城市资源利用和减少环境损失具有重要意义。本研究旨在利用印度瓦拉纳西地区的多日期Landsat卫星图像数据,分析1991-2001年期间城市绿地覆盖的变化及其与人口变化的关系。支持向量机(svm)分类器已被用于图像分类。利用土地消耗比(LCR)和土地吸收系数(LAC)等城市化指标了解城市覆被变化和人口动态。结果表明,随着人口的增加,城市覆盖值在时空尺度上都发生了显著的变化。

Monitoring Changes in Urban Cover Using Landsat Satellite Images and Demographical Information
The monitoring of urban cover is very important for the planner, management, governmental and non-governmental organizations for optimizing the use of urban resources and minimizing the environmental losses. The study here aims at analyzing the changes that occurred in urban green cover over a time span of 1991-2001 using multi-date Landsat satellite images data over the Varanasi district, India and its relation to demographical changes. The Support Vector Machines (SVMs) classifier has been used for image classification. The urbanization indicators such as Land Consumption Ratio (LCR) and Land Absorption Coefficient (LAC) were also used in order to understand the changes in urban cover and population dynamics. All the analysis indicates significant changes in the urban cover values with increasing population at both spatial and temporal scale.
