摘要
通过对木论国家级自然保护区主要森林植被类型枯枝落叶层的累积量、持水量及养分含量进行调查研究。结果表明 :林地枯枝落叶层累积量为 1 4 79～ 35 2 6t/hm2 ;净持水量为 1 8 73～ 5 8 2 0t/hm2 ;主要养分(N、P2 O3 和K2 O)含量为 1 95 94～ 6 82 99kg/hm2 ,其中N的平均含量分别是P2 O3 、K2 O含量的 1 3倍和 1
In the paper, the accumulation, water retaining and nutrient contents of litter in main vegetation were investigated and researched in national nature reserve at Mulum forest region. The result showed that the accumulation of litter in forest land was ranging 14 79～35 26?t/hm 2, net water retaining was ranging 18 73～58 20?t/hm 2, the content of main nutrients (N, P 2O 3 and K 2O) was ranging 195 94～682 99?kg/hm 2, but N was 13 and 14 times as average content as P 2O 3 and K 2O.
