环境梯度 meaning in Chinese
environmental gradient
environmentalgradient
Examples
- The results of twinspan indicated that the communities were classified into 10 associations , and the quadrats classification indicated two environmental gradients which were light intensity and soil humidity
Twinspan将翅果油树群落划分为10个群丛，分类矩阵图明显反映出光照强度和土壤湿度两个环境梯度。 - 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。 - The flavonoids content in the vegetative organs of stellera chamaejasme l . was determined by ultrasonic extraction and spectrophotometry in songnen grassland of heilongjiang province , and the change of flavonoids content in root was analysed under different environmental conditions , such as different grazing intensities and soil water content
摘要采用超声提取和分光光度法，对黑龙江省松嫩草地瑞香狼毒营养器官总黄酮含量进行了测定，并对不同环境梯度下根的总黄酮含量变化进行了分析。
