| 2. | Regulative model of soil factors for fast growth and high yield of eucalyptus grandis e . urophylla in south fujian hilly area
闽南山地巨尾桉生长的土壤主导因子调控模型研究 |
| 3. | 3 . using liner stepwise regression way , the author analysis the relationship between soil factors and biodiversity indices
有机质与群落物种丰富度、多样性指数以及均匀度指数jsi之间呈负相关。 |
| 4. | Beside the total capacity of calcium & magnesium , the other soil factors have no much difference between karst area and nonkarst area
这与土壤形成母质相关。土壤中其它调查因子在石灰岩和砂页岩地区总体区别并不明显。 |
| 5. | The soil factors affecting the capacity of fixing - ammonium in tested soils were mainly parent material , soil clay composition , ph , cec , organic matter , available n and concentration of nh4 + in soil
其影响因素主要有成土母质、粘土矿物组成、土壤阳离子交换量、 ph值、有机质含量、碱解氮含量和土壤溶液中铵离子浓度等。 |
| 6. | Analysis of species diversity and soil factors by single factor and stepwise regression revealed soil moisture , soil salt and soil ph have significant effects on species diversity ( / j < 0 . 01 )
分别对物种多样性和土壤指标进行了单因子和多元逐步回归分析，结果表明，土壤水分、盐分和酸碱度对物种多样性有显著影响( p < o 01 ) 。 |
| 7. | In spac , it is the plant that should be optimum indicator for irrigation control , because the soil factor and air factor , which control the balance of water in crops , can but be integrated by plant
而在土壤?植物?大气连续体(简称spac )中，植物才应该是是否需要灌溉的最优指示物，因为只有它们才能把控制植物水分平衡的土壤因子和大气因子综合起来。 |
| 8. | The results indicate that those soil factors , which are selected by the blending method of dynamical and statistical approaches , are useful for forecasting monthly summer precipitation and can expressly discover their dynamical relationships
结果表明对淮河流域夏季降水趋势的预测有很好的效果，且更加明确了土壤温、湿因子与降水异常之间的动力学联系。 |
| 9. | Additionally , through the use of clustering analysis , principal factor analysis and the correlation analysis , we found that the genetic structure of natural population reawnuria soongorica was related to the ecological factors ( soil factors mainly ) of the oasis - desert transitional zone
而其它土壤生态因子则与红砂的遗传多样性指数的相关性均不显著( p 0 . 05 ) 。表明红砂个体的分布可能与过渡带土壤的某些易溶性盐分相关。 |
| 10. | Experimental plots were established for thinning effects on stand and tree growth , tree species composition , species diversity and soil factors etc . in the mixed larch - spruce - fir stands which originated from planted larch pure forest by observations for 12 years after thinning
摘要以15块人工落叶松纯林演化后形成的落叶松云冷杉混交林为对象，间伐后12年观测结果，研究间伐对林分和树木生长、树种组成、物种多样性及土壤等因子的影响。 |
