摘要: 本文利用在三江平原沼泽地和开垦后裸地有关辐射平衡与小气候的大量实测数据,探讨沼泽表面辐射平衡的变化规律,并且用热平衡台站规范方法和土柱热含量方法计算土壤热通量,进而分析沼泽土壤温度和贴地气层温湿度的基本特征及开垦后小气候环境的演变,为合理开发利用和保护沼泽提供重要的科学依据。

Abstract: In the mire and reclaimed farmlands of the Sanjiang Plain, radiation balance, soil temperatute, and temperature and humidity of air were measured. And soil-heat flux was calculated with different methods. Through the analysis of a lot of data, the daily variations and the law of vertical distribution of microclimate factors on the bog surface were obtained. It is found that after the mire is reclaimed, the radiation balance increases, both soil temperature at different depths and air temperature of various height near the ground rise, and air humidity decreses obviously. Therefore, one should take the establishment of the artificial ecosystem of paddy, reed and fish breeding as the main developing direction of mire, at the same time, protect some mire in order to prevent the environment from getting dry, and maintain regional ecological balance.
