摘要
通过野外调查取样和室内实验分析,对丰宁满族自治县京冀水源保护林项目工程区内6种林分的林地水源涵养能力进行研究。结果表明:杨树纯林的枯落物层最大持水量和有效拦蓄量最大(5. 31t/hm^2、4.25t/hm^2),侧柏×山杏混交林的最小(1. 93t/hm^2、1. 57t/hm^2)。油松×山杏混交林的土壤层最大持水量和有效持水量最大(936. 66 t/hm^2,165. 32 t/hm^2),杨树纯林的最小(782. 84 t/hm^2,63. 25 t/hm^2)。6种林分中油松×山杏混交林的林地持水量最大,杨树纯林的最小。油松×山杏混交林的林地水源涵养能力最强,当地造林时可作为优选配置。
We studied the water conservation capacity of 6 stands in the construction area of Beijing Hebei ecological water conservation forest project in Manchu Autonomous County of Fengning through investigation and laboratory analysis.The results show that:For maximum water-holding capacity and effective holding-capacity of litter,pure Populus forest is the largest(5.31 t/hm^2,4.25 t/hm^2),Platycladus orientalis×Armeniaca sibirica mixed forest is the smallest(1.93 t/hm^2,1.57 t/hm^2).The soil of Pinus tabuliformis×Armeniaca sibirica mixed forest has the largest water-holding capacity and available water capacity(936.66 t/hm^2,165.32 t/hm^2),and the pure Poplar forest has the smallest(782.84 t/hm^2,63.25 t/hm^2).In 6 stands,Pinus tabuliformis×Armeniaca sibirica mixed forest’s capacity for water-holding is the best,pure Poplar forest’s is the worst.Water conservation capacity of Pinus tabuliformis×Armeniaca sibirica mixed forest is the strongest,which can use as a priority allocation in local afforestation.
