在泥质滩涂上，从先锋树种造林开始的一系列海防林建设措施，能有效加速滩涂土壤的脱盐过程，有林地土壤含盐量均低于１‰，且仅为滩涂对照的４１％～６２％；能改善土壤理化性状，＞０．２５ｍｍ的水稳性团粒含量，有林地是滩涂对照的１２～６５．５倍，有机质、全氮、有效磷等土壤养分，有林地分别是滩涂对照的２２～２４倍、２３～２７倍和１７～３４倍，还能提高土壤酶活性和微生物总量，有林地蔗糖酶等土壤酶活性是滩涂对照的２～３０倍，土壤微生物总量是滩涂对照的１１～２８９倍。 In muddy tidal flats, a series of measures to prevent the desalination of tidal flat soils from the forestation of avant-garde tree species can effectively accelerate the desalination process of the tidal flat soils. The soil salt content in the forestland is less than 1 ‰ and only 41% of that in the tidal flat. ~ 62%; Soil physical and chemical properties can be improved,> 0.25mm water-stable aggregate content, with forest land comparison is 1  2 ~ 65.5 times, organic matter, total nitrogen, available phosphorus and other soil nutrients, there The forestland was respectively from 22 to 24 times, from 23 to 27 times and from 17 to 34 times of the tidal flat control, but also to increase the soil enzyme activity and the total amount of microorganisms. There was soil such as woodland invertase Enzyme activity is 2 to 30 times of tidal flat control, and total amount of soil microorganisms is 11 to 289 times of tidal flat control.
