广东省滨海盐土分布在静水海湾和河流入海处,成片状分布。此区的盐土由河流冲积物堆积和海湖浸淹而成,属氯化物盐土。唐永銮等已经较为详细地论述了广东滨海盐土的形成过程及基本特性。由于广东沿海属于湿润季风热带和亚热带的气候范围,热量丰富,活动积温达7500—9000℃以上,雨量充沛,年雨量1500—1800毫米,每年有大量淡水入渗滨海盐土地区,加速了土壤脱盐速度。在成土过程中,由于热带亚热带植被的影响,又加之冲积母质中的有机质主要为浮淤生物形成的有机
Coastal saline soil in Guangdong Province is distributed in the waters of the Jingshui Bay and the rivers into the sea and distributes in sheet form. Salt in this area by the alluvial deposits of rivers and sea lake flooding, is a chloride salt soil. Tang Yongluan et al. Have discussed in more detail the formation process and basic characteristics of coastal saline soil in Guangdong. As the Guangdong coastal wet and tropical monsoon climate belongs to the tropical climate, rich in heat, the activity accumulated temperature of 7500-9000 ℃ above, abundant rainfall, annual rainfall 1500-1800 mm, annual freshwater infiltration of coastal saline soil area, accelerated soil desalination rate . In the process of soil formation, due to the influence of tropical and subtropical vegetation, the organic matter in alluvial parent material is mainly organic
