摘要

近年来，校园门户网站的建设越来越受到高校的重视.高校要切实提升门户网站的整体水平，就必须关注站点可访问性这一重要的网站质量衡量指标.本研究针对60所国内高校门户网站展开可访问性调查，对比WCAG 2.0的各项标准，分析目前国内高校门户网站的可访问性现状.研究发现，所有网站均未能通过WCAG 2.0的A级评测，各种不同层次高校门户网站的可访问性状况均不理想，网站可访问性错误点的集中度较高，最突出的四类可访问性问题依次为图片未添加描述文字、未正确定义文档语言、表单项label标签缺失和键盘控制缺失.针对以上问题，本研究提出了高校门户网站可访问性的改进建议.

Abstract

In recent years, more and more attention has been drawn to the construction of portal websites in colleges. In order to improve the college portal websites, the accessibility of the websites should be strongly concerned. Through a survey of 60 college portal websites in China, this research tries to provide an overview of the accessibility of Chinese college portal websites based on Web Content Accessibility Guidelines 2.0 (WCAG). The results indicate that none of the surveyed college portal websites meets the accessibility requirements of WCAG 2.0. Similar problems occur among different levels of college portal websites, and noncompliance errors within the guidelines are highly concentrated. The main accessibility problems are: (1) using images without text alternatives; (2) leaving language of pages undefined; (3) leaving input elements unlabeled; (4) lacking keyboard control. Finally, several valuable recommendations are made based on the research findings.

Key words： accessibility; college portal websites; WCAG 2.0
