| 摘 要： | 通过定位、半定位观测,对贵州喀斯特山区石漠化治理过程中土壤质量特性进行研究,探讨贵州喀斯特山区生态恢复过程中土壤特性以及土壤肥力变化规律。试验结果表明:喀斯特地区石漠化综合治理对土壤物理化学性质的影响较为明显,表现为表层土壤有机质增加,土壤容重降低,孔隙度增加,土壤理化性质改善,保水保肥能力和通道性增加;同时,土壤微生物数量增加,土壤微生物数量增加程度表现为细菌>放线菌>真菌,土壤肥力改善,生产力逐渐提高。 |
| 关 键 词： | 喀斯特石漠化 治理措施 土壤特性 微生物数量 |

| Abstract: | The soil physical properties and chemistry characteristic had been studied during controlling of karst rocky desertification process in the karst rocky mountainous areas. The result showed that: in controlling rocky desertification process, the numbers of individuals and density of plant increased with the degree of soil meliorated. Soil compaction decreased, and soil porosity, capacity of water and fertility holding increased, soil organic matter increased, these were associated with the soil organic matter contents and plant coverage, the total numbers of bacteria, antinomycetes and fungi increased. Bacteria was dominate group, the numbers was increased: soil bacteria> fungi > actinomycetes. Meanwhile soil fertility and productivity increased. |
| Keywords: | karst rocky desertification controlling model soil properties microbe quantity |
