本区海涂资源、类型及特点据有关部门统计,除已围10.3万亩以外,目前我区海涂资源尚有13.5万亩。其中,目前可围的有6.5万亩,需堵港促淤后可围的有7.0万亩。我区海涂,是江河泥沙入海后由海潮推托携带,在岛屿外围逐渐沉积升高形成的,属近代浅海沉积物,大都呈环状或带状分布。我区海涂土壤大都质地粘重,属咸粘土。土壤中含盐量高(氯化钠含量约在1％左右或超过1％),水源条件差,围后脱盐也较缓慢,一旦脱盐比较不易返盐。土壤理化性状极差,其
According to the statistics of relevant departments, except for the area of 103,000 mu, there are still 135,000 mu of sea-tainted resources in our district at present. Among them, the current can be surrounded by 6.5 million mu, need to stop blocking the siltation of 70,000 acres. The tideland in our area is carried by sea tide after it enters the sea and gradually forms in the outer periphery of the island. It is a modern shallow-sea sediment mostly distributed in a ring or belt shape. Most of our area of sea-tainted soil sticky weight, is a salty clay. Soil salt content is high (sodium chloride content of about 1% or more than 1%), poor water conditions, after the desalination is also relatively slow, once the salt is not easy to return to salt. Soil physical and chemical properties of very poor
