摘要: 对福建省武夷山自然保护区境内不同林龄甜槠林的水文学效应的比较研究表明,由甜槠林幼林至成熟林,其水文学效应逐渐增强,杯冠截流雨量、地表枯枝落叶持水能力、林地土壤水分稳渗率、蓄水能力等指标值随林龄的增长而增加;地表径流量与地下渗流量则呈下降的趋势.这说明成熟的森林植被-土壤系统在调节气候、涵养水源和保持水土等方面具有独特的作用和巨大的效能.

Abstract: Acomparative study on the hydrological effect of different age Castanopsis eyrei stands at theWuyi Mountains shows that C. eyrei stands of different ages have a markedly different hydrological effect. In an age-increasing sequence, an increasing trend of hydrological effect was observed. with increasing canopy interception increasing water-hoding capacity Of litter layer, increasing water infiltration rate and water holding capocity of forest land, and decreasing surfacerunoff and underground drainage. It is suggested that mature forest vegetetion-soil spstem has aunique role and a gigantic effect on adjusting climate, holding water source, and conserving water and soil, and hence, the mature forest land must be conserved especially.
