摘要:
利用主成分综合因子得分和灰色关联度分析理论对宁夏天然草地气象质量进行了综合评价，并对天然草地初级生产力与各气候因素间的相互关系进行了关联分析，研究各气象因子对天然草地初级生产力的制约效应。结果表明：宁夏干旱地区13个市县天然草地的气象质量可以划分为3个等级，半干旱区6个市县的天然草地的气象质量可以划分为2个等级。限制宁夏干旱区天然草地初级生产力最主要的气象因子是4~9月降水量，其次是年降水量、湿润度和年蒸发量；宁夏半干旱区天然草地初级生产力最主要的限制气象因子是湿润度，其次是4~9月降水量、年降水量和无霜期。
Abstract:
A comprehensive evaluation of the climate quality in Ningxia grassland,and a mutual relations between the primary productivity of natural grassland and the various climatic factors were analyzed by using integrated principal component factor scores and gray correlation analysis of the theory.The results showed that meteorological quality of the arid natural grassland in 13 cities and counties of Ningxia could divided into three grades;meteorological quality of the semi-arid natural grassland of 6 cities and counties of Ningxia could be divided into two grades.The most important meteorological factor constraining Ningxia primary productivity of natural grassland in arid areas was precipitation from April to September,followed by annual precipitation,humidity degree，and annual evaporation.In contrast,the most important meteorological factor in semi-arid regions was the humidity degree,followed by precipitation from April to September，annual precipitation and frost-free period.
