In this paper,with respect to the ordinal variables,the definitions of attribute reduction of dominance-based rough set approach in ordered information systems and ordered decision tables are given.Then the approach of sorting objects comprehensively using rough set theory is brought in to obtain a series of ranks.Based on these ranks,nonparametric methods to analyze correlation between two attribute subsets are introduced,and Spearman rank correlation coefficient is used as a measure of attribute correlation.Based on this measure,a new method of attribute reduction of ordered information systems and ordered decision tables is presented without changing the ordinal information of the universe.

In a scatter diagram, when the dots are distributed roughly along an ascending tendency, there is a positive correlation between the two sets of data. On the contrary, when the dots are distributed rough along a descending tendency, there is a negative correlation. However, when the dots scatter irregularly without a pattern, there is no obvious correlation.

在散点图中，如果点的分布大致上是由左下方至右上方，图像表示两组数据间有一个正相关关系；如果点的分布大致上是由左上方至右下方，图像表示两组数据间有一个负相关关系；如果点的分布大致上是不规则/凌乱地分布，图像表示两组数据间没有一个明显的关系。

The temporal and spatial distribution of SMP in tomato root zone and the correlation between tomato evaportranspiration and SMP variations were analyzed. The results showed that the variation of SMP among the soil profiles of 0, 15 and 30 cm from drip tape was insignificant, and the horizontal distance of tensiometers to drip tape had little effect on the correlation between tomato ETa and SMP variations. Lateral depths significantly influenced SMP from 20 to 70 cm soil layer and there were obvious effects of tensiometer depth on the correlation between tomato ETa and SMP variations.

对番茄根区土壤基质势时空分布和番茄耗水量与土壤基质势变化的相关性分析表明，水平距毛管0、15和30 cm 3个剖面间土壤基质势差异较小，负压计距毛管的水平距离对耗水量与土壤基质势变化的相关程度影响不大；毛管埋深对20～70 cm土层土壤基质势影响显著，负压计埋置深度对耗水量与土壤基质势变化的相关性影响显著，应依据毛管埋深确定负压计适宜埋置深度。
