Comparison on Water-holding Capability of Pinus massoniana Plantations with Different Densities
摘要
Abstract
The water-holding capability of litter and soil in 14-year-old Pinus massoniana plantations with different densities（including 2 m × 2 m,1.5 m × 1.5 m,2 m × 1.5 m and 1 m × 1.67 m） was compared in Zhenlong forest farm of Guangxi province.The results showed that litter accumulation was higher in 2 m × 1.5 m and 1 m × 1.67 m plantations,and the biggest value was in 1 m × 1.67 m plantation.There was positive relationship between litter accumulation and its maximum water-holding capacity（P0.01）.The maximum water-holding capacity of soil tended to be higher in 2 m × 2 m and 1.5 m × 1.5 m plantations.The integrated water-holding capacity depended on the size of water-holding capacity in soil.The order was 2 m×2 m1.5 m×1.5 m2 m×1.5 m1 m×1.67 m.Our study provided scientific basis for quantization of ecological function in Pinus massoniana plantations.关键词
