| 摘 要： | 以滇东北4种典型筇竹林为研究对象，对比分析不同类型筇竹林凋落物储量及持水性能，从而为滇东北筇竹林生态可持续经营提供理论依据和实践指导。研究结果表明，凋落物储量为人工筇竹-黄皮树混交林（7.61 t/hm2） > 天然筇竹-人工黄皮树混交林（6.61 t/hm2） > 天然筇竹-人工厚朴混交林（5.73 t/hm2） > 天然筇竹纯林（5.23 t/hm2）。凋落物最大持水量为天然筇竹-人工厚朴混交林（3.45 t/hm2） > 人工筇竹-黄皮树混交林（3.22 t/hm2） > 天然筇竹-人工黄皮树混交林（2.89 t/hm2） > 天然筇竹纯林（2.69 t/hm2）。4种类型筇竹林凋落物吸水速率均随着浸泡时间延长而逐渐趋于一致，筇竹混交林凋落物吸水速率高于筇竹纯林。凋落物的总有效拦蓄量为人工筇竹-黄皮树混交林（9.74 t/hm2） > 天然筇竹-人工厚朴混交林（8.95 t/hm2） > 天然筇竹-人工黄皮树混交林（7.73 t/hm2） > 天然筇竹纯林（6.23 t/hm2）。

| Abstract: | With 4 typical Qiongzhuea tumidinoda forests (referred to as Qiong bamboo forest) in northeast Yunnan as the research object, this paper compares and analyzes the amount and water holding capacity of litters from these forests, so as to provide theoretical basis and practical guidance for the sustainable management of Qiong bamboo forest in Northeast Yunnan. The results show that the litter amount in the 4 types of forests is ordered as artificial Qiong bamboo-Phellodendron chinense mixed forest (7.61 t/hm2) > natural Qiong bamboo-artificial Ph. chinense mixed forest (6.61 t/hm2) > natural Qiong bamboo-artificial Magnolia officinalis mixed fores (5.73 t/hm2) > natural Qiong bamboo pure forest (5.23 t/hm2). The maximum water holding capacity of litter is ranked as natural Qiong bamboo-artificial M. officinalis mixed fores (3.45 t/hm2) > artificial Qiong bamboo-Ph. chinense mixed forest (3.22 t/hm2) > natural Qiong bamboo-artificial Ph. chinense mixed forest (2.89 t/hm2) > natural Qiong bamboo pure forest (2.69 t/hm2). The water absorption rate of litter in the four types of forests tends to be the same as their soaking time expands, while the rate of water absorption of litter in Qiong bamboo mixed forest is higher than that of Qiong bamboo pure forest. The total effective intercept and accumulation volume of litter is as artificial Qiong bamboo-Ph. chinense mixed forest (9.74 t/hm2) > natural Qiong bamboo-artificial M. officinalis mixed fores (8.95 t/hm2) > natural Qiong bamboo-artificial Ph. chinense mixed forest (7.73 t/hm2) > natural Qiong bamboo pure forest (6.23 t/hm2). |
