摘要:
<正>以造林前立地情况基本一致为条件,选取雷州附城镇潮间带人工恢复的无瓣海桑红树林林地(分别于2000年、1997年和1995年造林)的3个代表性样地,对处于不同生态恢复阶段林地的土壤特性进行实验分析,结果表明该人工红树林生态恢复过程对生境中的土壤理化性质有显著影响,主要表现为随着红树林生态恢复的进展,土壤pH迅速降低,机械组成中粘粒比重、有机质含量、风干土壤含水量、可溶性SO2-4和全铁含量趋于增加,6年生林林地土壤具有红树林酸性硫酸盐土的基本特征,说明其成土过程为一快速过程。
Abstract:
The exotic Sonneratia apetala in Leizhou Peninsula has shown an outstanding fastgrowing ability in restored mangrove forests at the middle and high tide intertidal zone with yearround fresh water input from drainage.With condition of similarity of the environments before planting,three S.apetala plantation plotsplanted in 2000,1997,1995,respectivelyin Fuchen,Leizhou were selected for the mangrove restoration changes analyses on soil characteristics with a research goal to understand the mangrove restoration’s ecological process in soil.A total of 9 soil samples were collected in the field in April 2001.Test items included pH(Vsoil∶Vwater=2.5∶1,using electrical pH detector),wind dried soil’s water content(weight loss method,burning the samples in a burner at 105 ℃ for 5 h),physical partical component(Gravimeter test method),organic content(FeSO4 titration method),total salt contentAgNO3 titration method,total N(K2Cr2O7H2SO4 digestive method),total P(HClO4H2SO4 digestive and mixed indicator colorcomparison method),total Fe(Atom flamelight aborbing test method,using Detector SHIMADZUAA6 800),and water soluble ions of CO2-3/HCO-3Double indicators titration methodand of Ca2+,Mg2+ and SO2-4EDTA volume titration method.
