英文摘要 | The effect of visitors’ pressure on the spatial variability of soil properties was investigated in three open green areas in Tel Aviv. Six types of micro-environments were chosen: under oak and pine tree canopy with low (OL and PL) and high (OH and PH) visitors’ pressure; herbaceous area without visitors’ pressure (HE); and resting area under high visitors’ pressure (RA). For each micro-environment soil samples were collected from the upper 0-5 cm depth for organic matter content and moisture determination. Before sampling, soil surface compaction and litter biomass were measured. Soil properties were affected by visitors’ pressure and by the type of micro-environment. Soil organic matter content and soil moisture proved significantly higher under oak trees at low visitors’ pressure. Average litter biomass significantly decreased with increasing visitors’ pressure in the tree micro-environments. Average penetration depth decreased significantly with increased visitors’ pressure in all micro-environments. In all the cases where averages significantly decreased, variance significantly decreased too, but the coefficient of variations increased. This means that variances changed slower than averages. Changes in averages were accompanied by a change of data population structure, which indicated more soil spatial homogeneity under high visitors’ pressure. The data from different intervals of data population of soil properties demonstrated the different sensitivity to visitors’ pressure. |
