摘要
对深圳福田红树林 7年龄无瓣海桑 +海桑人工林生态影响的研究表明 :无瓣海桑 +海桑林 7年龄时 ,林下土壤颗粒组成发生改变 ,土壤含盐量升高 ,pH值降低 ,有机质、N、P、K、Pb、Cu、Zn等质量百分浓度升高 ;人工林促进了后缘天然林种群的生长及乡土红树幼苗进入天然林和人工林 。
In Futian Mangrove Natural Reserve of Shenzhen, the ecological influence of S.apetala+S.caseolaris plantations was studied. The results showed that the soil type changed, pH of the soil reduced, nitrogen, phosphorus, potassium, salt and heavy metals increased when the S.apetala+S.caseolaris plantations were 7 years old. In addition, the height and basic diameter growth of natural forest population were sped up because of this plantations , while the regeneration of natural forest quickened and developed toward sands ahead.
