摘要: 在确定了山区农业气候资源质量综合评价原则的基础上,建立评价的指标体系和评价标准,进而提出综合指数、模糊判别、希尔伯特空间距离系数等3种评价方法.本文以四川省开县为例,给出了农业气候资源环境质量的定量评价结果,并对3种评价方法进行了讨论和比较.

关键词: 气候资源, 综合指数, 模糊评价, 希氏距离系数

Abstract: Based on the comprehensive assessment principles of mountainous agroclimatic environmental quality being defined, the indices system and standards for assessment are established and, futhermore, three methods for evaluating (i. e. comprehensive index, fuzzy sets, and distance coefficient in Hilbert Space) are advanced. In this paper, the authors take Kaixian County, Sichuan Province as a example to make a detailed study on quantitative evaluation of agroclimatic environmental quality. Finally, the three methods are compared and discussed.
