对木麻黄更新迹地上引种的8年生6种相思树种林分涵养水源能力进行了比较,并以平潭2号木麻黄为对照,结果表明：与木麻黄相比,肯氏相思、厚荚相思和纹荚相思有更强的水源涵养能力,在6种相思中,地上部分持水量以厚荚相思为最高,达42.88 t.hm-2,大小排序为厚荚相思〉肯氏相思〉纹荚相思〉卷荚相思〉大叶直干相思〉马占相思;根系土壤层的持水能力以肯氏相思的土壤蓄水量最大,达1 795.02 t.hm-2;林分总持水量以肯氏相思最高,达1 824.04 t.hm-2,其次为厚荚相思和纹荚相思,分别达1 770.75 t.hm-2和1 759.60 t.hm-2。从涵养水源的能力角度来评判,肯氏相思、厚荚相思和纹荚相思作为沿海木麻黄防护林更新树种,有一定前景。更多还原

Water conservation function of six Acacia spp.of 8-year-old Casuarina equisetifolia on slash regeneration of coastal sandy land was compared.Pingtan No.2 Casuarina equisetifolia was taken as contrast.Result shows that compared to Casuarina equisetifolia,Acacia cunninghamii,Acacia crassicarpa ＆ Acacia aulacocarpa have stronger water conservation capacity.Above-ground water-holding capacity of A.crassicarpa is the highest of six Acacia spp.,being 42.88 t·hm-2.The descending order is A.crassicarpa〉A.cunninghamii〉A.aulacocarpa〉Acacia concinnatai〉Acacia auriculiformis〉Acacia magium.In soil part,soil water storage capacity of A.cunninghamii is the highest,being 1 795.02 t·hm-2;in the forest stand,the total water-holding capacity of A.cunninghamii is also the highest and it reaches 1 824.04 t·hm-2,followed by A.crassicarpa and A.aulacocarpa,respectively,being 1 770.75 t·hm-2 ＆ 1 759.60 t·hm-2.Judging from the perspective of water conservation capacity,A.cunninghamii,A.crassicarpa and A.aulacocarpa have some prospects as the regeneration tree species of coastal protection forest of Casuarina equisetifolia.
