1. 我们提出了一种非常规的程序（模糊编码）来构建生物和环境信息，它使用正分数来描述物种对给定变量的不同模式（即类别）的亲和力。模糊编码对于长期生态数据的综合是必不可少的，因为它可以分析来自各种来源（例如样本，文献）的各种生物信息。模糊编码表可以通过对应分析进行处理。以水生甲虫为例说明了这种模糊对应分析的性质。本文采用模糊编码表对法国上罗纳河的物种特征与生境时空变异的关系进行了研究。模糊对应分析可以用文中给出的方程进行编程，也可以使用ADE（环境数据分析）软件进行，该软件已被用于分析这种长期生态数据。在Macintosh Apple（TM）计算机上，ADE执行简单的线性排序，最近开发的方法（例如，与工具变量相关的主成分分析，规范对应分析，共惯性分析，局部和空间分析），并提供这些和其他类型分析（例如双标图，映射，建模曲线）的结果的图形显示。ADE由一个程序库组成，它利用了HyperCard（TM）接口的潜力。开放系统中的ADE，它为用户提供了各种工具来创建特定的程序序列。ADE的数学背景是由称为“对偶图”的代数模型支持的。
1. We present an unconventional procedure (fuzzy coding) to structure biological and environmental information, which uses positive scores to describe the affinity of a species for different modalities (i.e. categories) of a given variable. Fuzzy coding is essential for the synthesis of long-term ecological data because it enables analysis of diverse kinds of biological information derived from a variety of sources (e.g. samples, literature).2. A fuzzy coded table can be processed by correspondence analysis. An example using aquatic beetles illustrates the properties of such a fuzzy correspondence analysis. Fuzzy coded tables were used in all articles of this issue to examine relationships between spatial-temporal habitat variability and species traits, which were obtained from a long-term study of the Upper Rhone River, France.3. Fuzzy correspondence analysis can be programmed with the equations given in this paper or can be performed using ADE (Environmental Data Analysis) software that has been adapted to analyse such long-term ecological data. On Macintosh Apple(TM) computers, ADE performs simple linear ordination, more recently developed methods (e.g. principal component analysis with respect to instrumental variables, canonical correspondence analysis, co-inertia analysis, local and spatial analyses), and provides a graphical display of results of these and other types of analysis (e.g. biplot, mapping, modelling curves).4. ADE consists of a program library that exploits the potential of the HyperCard(TM) interface. ADE in an open system, which offers the user a variety of facilities to create a specific sequence of programs. The mathematical background of ADE is supported by the algebraic model known as 'duality diagram'.
