运用地统计学方法与GIS相结合,对坡面不同种植方式(横坡、顺坡)下低山丘陵茶园土壤有机质的空间变异进行了研究。结果表明:横坡种植与顺坡种植方式下土壤有机质含量都具有中等程度变异,变异系数分别为34.05%和20.59%。横坡、顺坡两种种植方式下土壤有机质含量具有强烈的空间相关性,C0/(C0+C)值分别为20.9%和24.8%;在横坡种植方式下有机质含量空间相关距离为42m,而在顺坡种植方式下空间相关距离为17m。横坡种植方式下土壤有机质在东西方向上表现出各向异性,与地形表现出很好的一致性;在顺坡种植方式下土壤有机质在东西、南北方向上都有明显的趋势特征,表现出各向异性。
By using the combination of geostatistics and GIS, the spatial variability of soil organic matter in tea plantation in hilly area was studied under different planting modes (slope, slope). The results showed that there was a moderate degree of variation in soil organic matter under both horizontal and downslope planting, with coefficients of variation of 34.05% and 20.59%, respectively. There was a strong spatial correlation of soil organic matter content under the two planting patterns of slope and slope. The values of C0 / (C0 + C) were 20.9% and 24.8%, respectively. The spatially dependent distance of organic matter under the slope planting was 42 m, While the spatial correlation distance in the slope planting mode is 17m. In the aspect of slope slope planting, the soil organic matter showed anisotropy in the east-west direction and showed good consistency with the topography. Under the slope-slope planting mode, the soil organic matter had obvious trend characteristics in the east, west and north directions Anisotropy.
