Impacts of Different Ecological Restoration Measures on Litter Production and Its Nutrient Fluxes in Red Soil Erosion Region
摘要
Abstract
Based on field investigation and lab analysis,after 27 years later,litterfall production and its nutrient fluxes were analyzed in red soil erosion region with four kinds of ecological restoration measures as Pinus massonian forests,Pinus massonian forest with planting grass and bamboo-burl-groove,Pinus massonian forest with bamboo-burl-groove,Pinus massonian without disturbance.Result showed that annual litterfall amount in the four ecological restoration measures was estimated at 3 267.30,3 530.58,3 937.67,4 997.88 kg/hm^2,respectively,showing a significant increase with Pinus massonian without disturbance.The year dynamic of litterfall for four ecological restoration measures showed a single peak in summer（August）.Annual fluxes of the five nutrient elements via litter in the four ecological restoration measures were 33.83,38.90,48.39,64.40 kg/hm^2,respectively,and following order was：Pinus massonian without disturbancePinus massonian forest with bamboo-burl-groovePinus massonian forest with planting grass and bamboo-burl-groovePinus massonian forests.N flux of litterfall in the four ecological restoration measures ranged between 23.33 kg/hm^2 and 47.60 kg/hm^2,K ranged between 5.40 kg/hm^2 and 8.62 kg/hm^2,Ca ranged between 4.02 kg/hm^2 and 6.33 kg/hm^2,Mg ranged between 0.58 kg/hm^2 and 0.89 kg/hm^2,P ranged between 0.50 kg/hm^2 and 0.96 kg/hm^2.关键词
