| 1. | Study on the spatial variability of water nitrogen and phosphorus in the zhalong wetland 营养物质空间异质性研究 |
| 2. | Application of geo - statistics in spatial heterogeneity of soil nutrients in wetlands 地统计学在湿地土壤养分空间异质性研究中的应用 |
| 3. | Relationship between water character and yield component under different distribution patterns of winter wheat population 毛乌素沙地不同林龄沙柳表层土壤水分空间异质性 |
| 4. | The modifiable areal unit problem of spatial heterogeneity of vegetation communities in the transitional zone between oasis and desert 荒漠绿洲过渡带植被空间异质性的可塑性面积单元问题 |
| 5. | The properties of soil are not homogeneous , whereas soil is a continuous spatio - temporal heterogeneity , with high spatial variability 土壤并非一个匀质体,而是一个时空连续的变异体,具有高度的空间异质性。 |
| 6. | The traditional methods of describing soil properties are on the whole qualitatively soil classification , not researching soil spatial variability quantitatively 传统描述土壤空间异质性的方法基本上是定性地土壤分类,而不是定量地研究土壤空间变异。 |
| 7. | After year ' s cultivation , the different soil fertility of each site resulted in diversities of soil productivity , which show the high spatial variability of soil fertility 土壤耕作多年,每个田块的土壤肥力不同导致生产力的不同,说明土壤养分含量具有高度的空间异质性。 |
| 8. | The results are as following : the soil nutrients , such as organic matter , total n , available k and hydrolytic n , and the soil moisture under the shrubs of s . vulgaris were heterogeneously distributed 研究结果如下:天然臭柏灌丛地土壤水分,有机质、全氮、速效钾和碱解氮(速效氮)等养分含量的分布具有空间异质性。 |
| 9. | With the expansive terrain , the regional differences of the natural resources gift and the social and economic development are remarkable in china . the mode of land use , the structure of regional land use and the extent of land use are very different in spatial distribution 中国地域辽阔,自然资源禀赋与社会经济发展的区域差异显著,土地资源的利用方式、区域土地利用结构、土地利用程度等具有高度的空间异质性。 |
| 10. | That of available potassium showed the interruption of human activities with the highest value ( 81 . 2 % ) , and of cec , total potassium , available copper showed that spatial auto - correlation was master with the value less than 25 % . there was no relationship between spatial variability and distance , but with the nugget of 0 . 2 , therefore , the distance Kropng插值结果进一步表明土壤表层养分含量具有高度的空间异质性,决定了空间格局的存在,养分含量的斑块( patch )的大小、形状及空间分布等具有显著的差异,但是不论在什么方向,养分含量由低到高的分布梯度规律总是存在的。 |
