查询词典 variation

The organic matter and total N"s variation of the upper and below layer were identical whose range remained constant in each season; the soil NlV-N content in the upper layer was higher than hi the below in Spring and Autumn, but this change was complicated hi Summer and Winter owing to different forest measures; the peaks and valleys of NCV-N hi the upper and below soil layer appeared in the same tune, but the change showed no laws in different forest lands; the variation of the available N was approximate to NHU+-N; the range of each layer"s change of the hydrolysable N was identical that appearedparallel lines in figure.

土壤上下层有机质、全氮量的时间变化趋势相同，层间差异量基本维持在恒量水平；春、秋季铵态氮含量上层明显高于下层，夏、冬季随还林措施不同而表现复杂；上下层硝态氮波谷、波峰的出现时间大致相同，但不同还林地的变化规律较复杂；速效氮的变化趋势与铵态氮类似；土壤上下层水解氮的时间变化几乎同步，在图上表现为两条近似的平行线。

Study shows that,pH smallest coefficient of variation was 12.95%,coefficient of variation of soil available phosphorus was the largest,varia...

研究表明，pH的变异系数最小为12.95%，土壤有效磷的变异系数最大，变异值达到了122.18%；经克里金插值分析，研究区土壤养分的空间相关性减弱，朝均一化发展，这说明了红花套镇土地养分变化受人为因素影响较大，当地的土壤适合并已形成大面积的发展种养殖业，传统的稻、麦、棉种植数量和产量都与红花套镇的人平纯收负相关，对当地人平纯收贡献最大的是柑桔总产，相关系数分别为0.822，0.966，土地利用效率最大的是水产品养殖，相关系数分别为-0.760，0.870。
