关于景观格局演变研究的几个问题

针对特定的生态过程,将景观格局与生态过程相结合的格局分析是未来景观格局研究发展的方向。景观格局变化与景观过程改变互为因果,了解格局演变时空规律及其演变驱动机制是结合生态过程进行景观格局分析的前提与基础。文章归纳了景观格局演变分析方法有景观格局指数与景观空间统计特征比较法、马尔柯夫转移矩阵法和主要以细胞自动机理论为基础的景观格局动态模拟。主要分析了景观格局演变的人文驱动力系统,介绍典型相关分析与逐步回归分析两种定量判别景观格局演变驱动力的方法,简要总结景观格局演变的驱动机制。最后提出今后研究所要突破的方面。

Several Problems about Landscape Pattern Change Research

The analysis of landscape pattern is one of the fundamental research scopes in Landscape ecology. Presently, most landscape pattern research only describes its geometric feature. Aiming at a special ecological process, combining ecological process with landscape pattern is the development trend of landscape pattern research in the future. Landscape changes at all time, pattern change is one aspect of landscape dynamic. The changes of landscape pattern and landscape process are each other cause and effect. The spatial and temporal rule of landscape pattern change and which driven mechanical is the foundation of landscape pattern change research combining with ecological. This thesis discusses several problems of landscape pattern change, the methods of landscape pattern change analysis include comparison of landscape pattern index and the landscape spatial statistical characteristic, Markov transition matrix and the simulation of landscape pattern change course .The driven factors of landscape pattern change are systemic. The methods to discriminate the main driven factors of the landscape pattern comprise canonical correlation analysis and stepwise regression analysis. There are some difficulties for the researcher to study the landscape pattern change, including data, scale and the inter-disciplinary collaboration etc.
