城市用地景观结构变化与机制的遥感研究——以浙江省义乌市为例

Research on Changes and Mechanism of Urban Landscape Structure by Remote Sensing

采用遥感结合景观分析方法,对义乌市城市用地景观结构变化进行研究。结果表明,义乌市人文景观快速发展的同时,景观密度不断减小,用地集约度不够;人为强干扰作用使城市自然景观发展滞缓,景观结构合理性不足;分析其变化机制,发现人口和经济因素与之关联密切,并构建了变化数学模型。

With remote sensing technologies and landscape analysis methods, the structure changes of urban landscape in Yiwu city were researched. Results showed that patch density of urban landscape gradually decreased while artificial landscape developed rapidly. Land use intensity was not enough. Human strong disturbance ,caused the delay of urban natural landscape and the lack of rationality in landscape structure. Through analyzing the change mechanism, it was found out that population and economy had close correlation, which could be expressed by mathematic model.
