Abstract
[Objective] The differences of water conservation ability of litterfall and soil of seven-year old Camptotheca acuminata plantation,Betula luminifera plantation and Pinus massoniana plantation were comparied,so as to provide the scientific basis for raising the water conservation ability of forest.[Method] Field investigation mixed with interior method for determination of water conservation capacity.[Result] The order of maximum water-holding capacity of litter layer in different forest types was showed B.luminifera plantation ＞ C.acuminata plantation ＞ P.massoniana plantation,the order of soil bulk density were follow as P.massoniana plantation ＞ B.luminifera plantation ＞ C.acuminata plantation,soil total porosity showed the trend of C.acuminata plantation ＞ B.luminifera plantation ＞ P.massoniana plantation,the field moisture capacity and capillary moisture capacity of soil in different forest types followed the order of B.luminifera plantation ＞ P.massoniana plantation ＞ C.acuminata plantation,whereas,max soil moisture capacity show follows the order of C.acuminata plantation ＞ P.massoniana plantation ＞ B.luminifera plantation.Soil water storage capacity among 0 ～ 40 cm of C.acuminata plantation was the largest,and P.massoniana plantation was the smallest.The sequence of water conservation of litter and soil in different forest types were showed that C.acuminate plantation (275.68 t/hm2) ＞ B.luminifera plantation (255.94 t/hm2) ＞ P.massoniana plantation (246.76 t/hm2).关键词
