我国海岸线长,且大部分为淤进性海岸带,陆地每时每刻在向大海延伸。就江苏省而言,堤外海涂有700多万亩,堤内已围待垦海涂300多万亩,并且每年还以2万余亩的速度向外淤进。迅速将这些海涂土壤资源变为农业利用土壤,对我国东部人口密集区的生产发展会产生较大的影响。 解放初期,我国土壤科学工作者就开始
Our coastline is long and mostly silt coastal, with the land extending all the way to the sea. In terms of Jiangsu Province, there are more than 7 million mu of seawalls outside the embankment, and more than 3 million mu of reclaimed seawalls have been surrounded by the embankment, silting in with an additional 20,000 mu each year. The rapid transformation of these tidal flat soil resources into agricultural land use will have a significant impact on the production development in the densely populated eastern part of China. In the early days of liberation, our soil scientists started
