- 摘要:
- 在福建中亚热带红壤区,将侵蚀经济林(油茶)改造成人工草地(人工植草)、封山育林(自然恢复)进行生态恢复,11a后,分析A-C层土壤的常规理化性质、土壤复合量、原土复合度、腐殖质结合形态用以评价土壤肥力变化.结果表明：不同土层各指标有明显差异,其中土壤速效养分、有机质、土壤复合量表现为A层>B层>C层,原土复合度则表现为C层>B层>A层.土壤腐殖质在C层呈松结合态向紧结合态转变的趋势,其中在自然恢复区B、C层土壤的松/紧比值较A层分别下降0.149,0.458个单位,人工植草区C层土壤的松/紧比值较A层下降0.292个单位,松结合态向紧结合态转变速度较自然恢复区有所减缓.人工植草区A层土壤的有机质及有机碳总量虽低于自然恢复区,但重组有机碳含量相近,其它测定指标亦无明显差异.
- Abstract:
- The study was conducted on the effect of 2 kinds of restoring measure,planting forage(PF),natural regradation(NR) to the quality of soil in eroded Camelia oleifera forest in subtropical region of Fujian Province,China.The results show that layer A enjoy the best at contents of soil available nutrient,organic matter,and degree of soil organo-mineral complexing,second by layer B,worst by layer C.But,at content of soil complexes,the trend is layer C>layer B>layer A.When humus of combined types of soil was tested,it seems that humus could be transferred from tightly-combined type to loosely-combined type on deeper soil layer.In plant forage plot,ratio of types between loosely-combined and tightly-combined were decreased 0.149,0.458 on soil of layer B and C,compared with layer A.In NR plot,the ratio was decreased 0.292 on soil of layer C,compared with layer A.as analyzing on restoration effect of difference measure,it seems that humus transformation rate from tightly-combined type to loosely-combined type is slower in PF plot.No difference was found on key index,including available nutrient,carbon content of heavy soil on soil of 2 restoring plot,although organic matter content was lower in PF plot than in NR plot.
