【摘要】 对人工促进植被恢复对基岩质海岸防护林的土壤生态特性的影响进行研究。结果表明:(1)沿海岩质海岸防护林土壤含水率普遍较低,并随着土层增加相应减少。经人工促进植被恢复的化香纯林土壤含水率最高,北江荛花檵木混交林土壤容重最小。两样地总孔隙度和毛管持水量增加,其它各样地间差异不明显;(2)沿海岩质海岸防护林土壤养分含量差异较大,6个试验样地的土壤全氮、水解性氮、全磷、速效钾及有机质含量均明显高于对照地,其中土壤全氮、水解性氮、全磷及有机质含量均以经人工促进植被恢复的北江荛花檵木混交林最高,土壤速效钾含量以化香纯林最高。更多还原

【Abstract】 Effects of artificial promotion of vegetation rehabilitation on soil ecological properties of rocky coastal protective forest were studied.The results showed that: Available soil water content of rocky coastal protective forest were lower,and decreased with soil layers.Soil water content of Platycarya strobilacea plantation effected by artificial promotion of vegetation rehabilitation was the highest.Soil bulk density of the forest mixed Pinus elliotti with Schima superba was the lowest.Full porosity and capillary porosity of the two vegetation types increased,but the differences between the others were indistinctive.Considerable differences of soil nutrient contents were found in different vegetation types.Total-N、hydrolyzable nitrogen、total-p、available potassium and soil organic matter of the 6 test vegetation types were all higher than that of control sites.Total-N、hydrolyzable nitrogen、 total-p and soil organic matter of the forest mixed Pinus elliotti with Schima superba was the highest.Available potassium of the Platycarya strobilacea plantation was the highest.更多还原
