摘要
对严重侵蚀红壤封禁管理马尾松林的水源涵养功能进行了研究 ,结果表明 :封禁管理后的马尾松林总持水量为 1717 872t/hm2 ,比对照的大 2 19 112t/hm2 ,其中地上部分持水量为 2 4 72 2t/hm2 ,是对照的 2 7 2倍 ,土壤 0～ 40cm土层最大持水量为 1693 15t/hm2 ,比对照的高 196 2 1t/hm2 ;表土层的初渗率和稳渗率均比对照的高。
The paper studies on water conservation function of masson pines that growing on severe eroded red soil and managed through grazing ban. The results show that after grazing ban management the total moisture content of masson pines is 1 717.872 t/hm 2 , 219.112 t/hm 2 more than that of the checked one. Of which, 24.722 t/hm 2 is above the ground which is 27.2 times of the checked one, the maximum moisture content at 0～40 cm layer is 1 693.15 t/hm 2 , 196.21 t/hm 2 more than that of the checked one. The initial permeability and stable permeability of topsoil are higher than that of the checked ones. It shows that water conservation function of masson pines managed through grazing ban has been rehabilitated to a certain degree.
