摘要
泥炭是由于植物残体积累大于微生物分解量的结果,两者都与水热条件有密切关系,是特殊水热条件组合长期持续的产物.作者对中国亚热带、热带地区6省(市)9个观测点进行了46次野外定点观测工作,通过大量实测数据,探明泥炭累积与植物生长、微生物分解与气候、地表水、酸碱环境的关系.初步进行了地表积水环境的大气湿度与水中溶氧量的关系的研究.证明大气湿度影响水中的溶解氧,溶解氧影响到微生物分解,从而制约泥炭的累积,探讨了环境中草本植物分解与水热条件和微生物区系的相关性,揭示了亚热带草本泥炭形成的生物一环境机制.
Turf Deposits are resulted from plant ramnants on condition that they are accumulated faster than decomposed. Both functions are closely related to the liquid-heat conditions of the environment and are the result of its sustained processing. Through a vast amount of data which the authors collected by field surveying on nine spots distributed in six provinces (cities) of tropic and subtropic zones, the relationship between turf deposits and plant growth, as well as that between microbic decompos-tion and climate, surface water and acid-alkali environment are verified. A research on the relationship between the humidity of atmosphere and the dissolved oxygen in water has been carried out. The result showed that the quantity of dissolved oxygen will be affected by humidity, and the former in turn will effect microbic decomposition and turf accumulation. Finally, the relativity between the herbage decomposition and the liquid-heat conditions and microbic systems was discussed and the bio-environmental organism in the forming of herbal turf deposits in the topic and subtropic zoned clarified.
