Spatial variability of community characteristics and above - ground biomass of functional group in degraded sandy grassland 退化沙质草场群落特征及功能群生物量的空间变异性
Spatial variability of community characters and functional group diversity in a degenerated sandy steppe in horqin sandland 退化沙质草场群落特征及功能群多样性的空间变异性
Secondly , a real - time forecast model of irrigation schedule is obtained at irrigation district scale , taking into account the spatial variability ( 2 )构建了考虑空间变异性的灌区尺度的实时灌溉预报模型。
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。
Spatial variability of soil moisture in the irrigation district is analyzed by integrating geostatistics and general theory of statistics 将地统计学法和传统统计学方法相结合,对灌区尺度的土壤水分空间变异性进行了研究。
The spatial variability at all of soil layers was contributed to the influencing of the correlation rather than of the random 进一步分析表明,各层次土壤无机碳和有机碳的空间变异主要是由空间自相关部分引起的,由随机因素引起的空间变异小。
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。
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。
It was showed that the soil moisture had great temporal and spatial variability in catchment scale due to the joint - influence of land use , topography , physiognomy , and other factors 受地形地貌、土地利用和时间等因素的综合作用,土壤含水量在流域尺度内具有较大的时空变异性。
Numerical experiment shows that this heterogeneous disturbance arising from soil water content ' s spatial variability cannot be neglected when regional mean evaporation fluxis estimated 数值试验表明,这种因空间变率而引发的非均匀扰动项在估计区域平均通量时具有不可忽视的影响。
Spatial variability occurs when a quantity that is measured at different spatial locations exhibits values that differ across the locations. Spatial variability can be assessed using spatial descriptive statistics such as the range.
