景观格局定量分析中的不确定性

景观生态学作为一门交叉学科，随着遥感与地理信息系统的发展，景观格局定量分析成了景观生态研究中的重要数量方法。景观格局定量分析方法作为研究景观结构组成特征和空间配置关系的重要方法，它的不确定性制约着景观生态学的发展及在实践中的指导作用。克服定量分析过程中的不确定性是景观生态学一个重要的研究课题。从景观格局定量分析的数据源、方法和全过程与解释，阐明不确定性在不同分析阶段的产生、传递和累积，探讨不确定性的解决方法。

Uncertainty of the Quantitative Analysis on Landscape Patterns

Landscape ecology plays an important role in the conservation and regeneration of ecological environment and quantitative analysis on landscape patterns has become as an important quantitative method in researching landscape ecology including the composition characteristics of landscape structure and the spatial distribution of landscapes along with the development of remote sensing and geographical information system. However, the uncertainty of the quantitative analysis on landscape patterns restricts the development of landscape ecology and its guiding significance in practices. How to find a solution of the uncertainty of quantitative analysis on landscape patterns is an important research subject of landscape ecology. In this paper, the occurrence, transfer and accumulation of the uncertainty of quantitative analysis on landscape patterns at the different stages are discussed based on the data sources, analysis method and process as well as explanation of the quantitative analysis on landscape patterns, and the solution of the uncertainty of quantitative analysis on landscape patterns is researched. It is considered that the uncertainty of quantitative analysis on landscape patterns should be paid a great attention to, especially in evaluating the precision of the classified results of landscapes and analyzing the confidence. It is suggested to systematically research the uncertainty of quantitative analysis on landscape patterns based on the theories of remote sensing, geographical information system, spatial modeling, geography, ecology, etc. so as to promote the further development of landscape ecology.
