摘要
为揭示易县清西陵古油松林枯落物的持水能力特征，本研究以河北省保定市易县清西陵的古油松纯林为研究对象，对古油松纯林的枯落物持水特性、拦蓄量进行调查，并分析其枯落物持水能力特征。结果表明，不同林龄古油松林总枯落物的最大持水量表现为: 200a（55.78t hm-2）>300a（54.67 t hm-2）＞150a（43.33 t hm-2），不同林龄总枯落物的最大持水率表现为:200a（165.61%）>300a（152.95%）＞150a（151.58%）；总枯落物层最大拦蓄量和有效拦蓄量均呈现出200a>300a>150a，最大拦蓄量介于34.00-43.11 t hm-2之间；有效拦蓄量介于37.50-34.91 t hm-2之间。最大拦蓄率与有效拦蓄率呈现出相同的趋势，均为200a>300a>150a。200a古油松林的枯落物层具有最优的持水效能。
Abstract
To reveal the water-holding capacity characteristics of ancient pine forest litter in the Qing Western Tombs of Yixian County, this study focused on pure ancient pine forests in the Qing Western Tombs of Yixian County, Baoding City, Hebei Province. The research investigated water-holding properties, and interception capacity of the ancient pine forests, analyzing their water-holding capacity characteristics. The results showed that the maximum water-holding capacity of total litter in ancient pine forests of different ages was: 200a (55.78 t hm-2) > 300a (54.67 t hm-2) > 150a (43.33 t hm-2). The maximum water-holding rate of total litter exhibited the following trend: 200a (165.61%) > 300a (152.Water retention characteristics of fallen material in the ancient pine forest of Qingxi Tombs95%) > 150a (151.58%). Both the maximum interception capacity and effective interception capacity of the total litter layer showed the same trend: 200a > 300a > 150a, with the maximum interception capacity ranging between 34.00 and 43.11 t hm-2, and the effective interception capacity ranging between 37.50 and 34.91 t hm-2. The maximum interception rate and effective interception rate followed the same trend, both being 200a > 300a > 150a. The litter layer of the 200a ancient pine forest demonstrated the optimal water-holding efficiency.关键词
