基于多样性指数的临港新城景观格局演变分析

Landscape Pattern Change Analysis of Lin'gang New City Based on Diversity Index

在景观生态学研究中,理解与把握景观格局变化的生态学原则至关重要。用景观指数描述景观格局及变化,建立格局与景观过程之间的联系,是景观生态学最常用的定量化研究方法。文章在综台前人对景观指数的基础上,对景观指数研究,选择以香农多样性指数作为判定标准,结合遥感、GIS技术,对上海临港新城的生境破碎化状况和动态,以及景观格局演变进行了研究,探讨了近10年来临港新城景观格局演变的机理及驱动机制。

In the research on landscape ecology,it is essential to understand and grasp the principles of ecology for landscape pattern changes.Describing the landscape pattern and changes by using landscape indices and establishing links between the pattern and process is the most common methods of quantitative study of the landscape ecology.On the basis of combining with the before landscape indices,this article studies the landscape indices,selects to the Shannon diversity index as a criterion,combines remote sensing,GIS technology,and studies the habitat fragmentation state and dynamics of Shanghai Lingang new town and landscape pattern change,explores the mechanism and driving mechanism of landscape pattern change in early 10 years.
