摘　　要：为提升济南南部山区水源涵养林的保水功能,以侧柏林、黑松林、刺槐林和荆条林为对象,对其土壤水文特性和酶活性进行了分析。结果表明:(1)侧柏林、黑松林、刺槐林的毛管孔隙度、总孔隙度、毛管持水量、饱和贮水量、涵蓄降水量、有效涵蓄量整体高于荆条林,而土壤容重、非毛管孔隙度、非毛管持水量整体低于荆条林。其中侧柏林的毛管孔隙度、总孔隙度、毛管持水量、饱和贮水量、涵蓄降水量、有效涵蓄量增幅最大,分别为荆条林的1.87、1.43、2.62、1.43、1.56和2.50倍。(2)侧柏林和刺槐林的脲酶、多酚氧化酶活性显著高于荆条林(P<0.05)。(3)土壤容重与土壤脲酶、多酚氧化酶活性呈极显著负相关(P<0.01);毛管持水量、饱和贮水量、有效涵蓄量与脲酶、多酚氧化酶活性呈极显著正相关(P<0.01)。侧柏林在提高有效水利用、涵蓄降雨量、有效水分贮存、酶活性等方面均好于黑松林、刺槐林和荆条林。济南南部山区的水源涵养林营建中应尽量优先考虑营造侧柏林。Taking Platycladus orientalis,Pinus thunbergii,Robinia pseudoacacia&Vitex negundo plantations as research subject,the soil hydrological characteristics and enzyme activities of the water conservation forests were analyzed to improve the water conservation effects in the southern mountainous areas of Ji’nan City.Result shows that:(1)The capillary porosity,total porosity,porosity ratio,capillary water holding capacity,capillary saturated water holding capacity,saturated water holding capacity,precipitation holding capacity&effective water holding capacity of the forest are all higher than those of V.negundo forest,while the soil bulk density,non-capillary porosity&non-capillary water holding capacity are all lower than those of V.negundo forest.Among them,the increase of capillary porosity,total porosity,capillary water holding capacity,saturated water storage capacity,storage precipitation&effective water storage capacity of P.orientalis plantations is the largest,which is 1.87,1.43,2.62,1.43,1.56&2.50 times respectively of that of V.negundo forest.(2)The activities of urease&polyphenol oxidase in P.orientalis&R.pseudoacacia plantation are significantly higher than those in V.negundo forest(P<0.05).(3)Soil bulk density is extremely negatively correlated with soil urease&polyphenol oxidase(P<0.01).The capillary water capacity,capillary saturated water holding capacity&effective water storage are positively correlated with urease&polyphenol oxidase(P<0.01).In short,P.orientalis plantation is optimal than P.thunbergii,R.pseudoacacia&V.negundo of plant effective water use,storage precipitation,effective water storage&improvement of enzyme activity.In the construction of water conservation forest in the southern mountainous area of Ji’nan,priority should be given to the afforestation of P.orientalis as far as possible.
