第二轴 meaning in Chinese
secondary shaft
Examples
- The results of dca suggested the first axis showed light gradients and the second axis reflected humidity gradients
Dca排序结果表明，第一轴反映了光照梯度，第二轴反映了水分梯度。 - The first axis of dca indicated the water gradient of soil while the second axis reflected the altitude gradient . the moisture of soil descend from left to right , while the altitude ascend from down to up
Dca排序第一轴反映了土壤水分梯度，从左到右土壤含水量在不断下降；第二轴反映了海拔梯度，从下到上海拔高度在不断升高。 - The result of dca ordination shows that diffirent plant communities and their distributing area vary with the environmental grads in the ordination graph when the first axis of dca denotes altitude change and the sencond axis of dca denotes change of water equivalent in the soil
Dca排序结果表明， dca第一轴反映海拔变化， dca第二轴表示土壤含水量的变化，随着环境梯度变化，不同的植物群落在排序图上也有各自的分布范围。 - The first axis of dca ordination reflects a synthetic environmental gradient , positively correlated with precipitation , humidity , heating , primary productivity , and potential evaporation etc . the second axis of dca represents changes in altitude and longitude
Dca排序第一轴表现了一个综合的环境梯度，即从左到右，降水、湿度、热量、初级生产力、潜在蒸发量逐渐增强， dca第二轴反应了海拔和经度的变化，即从上到下，海拔降低、经度增加。 - By using of the richness , diversity and evenness indices , combined with twinspan , dca , dcca , multi - factors regression , correlation analysis techniques and so on , species diversity and diversification mechanism were studied . the communities were classified into eight types by twinspan . the first axis of dca indicated basically the diversification of soil water , while the second axis indicated basically the disturbance degree by people . the correlations between n , organic matter , elevation and the first axis are negative association , and the others are positive
通过丰富度指数、物种多样性指数和均匀度指数，结合twinspan 、 dca 、 dcca排序，多元回归和相关分析，研究了物种多样性及其变化机制，把植物群落分为8个群落类型；物种多样性指数的dcca第一轴基本上反映了土壤水分的变化，第二轴基本上反映了人类对群落的干扰程度，物种多样性指数随土壤水分的增加而增大，随人类的干扰程度的增加而减小。
