| 5. | Article 23 land reclamation at the expense of deforestation , rock quarrying , sand quarrying , soil extracting and other activities at the expense of deforestation shall be forbidden 第二十三条禁止毁林开垦和毁林采石、采砂、采土以及其他毁林行为。 |
| 6. | The chemical analysis of the soil extracted solution has shown that the soluble salt in the soil is predominated by the divalent ions ca2 + and mg2 + which mean that the soil aggregates have been chemically stable during the field experiment 同时,对土壤浸剂液的化学成分的分析结果表明,浸提液中二价的钙、镁离子占优势,这使土壤微团聚体处于一种化学稳定的状态。 |
