摘要: 以嘉陵江流域低山暴雨区水土保持低效林为研究对象,经过调查,选择旺苍县营造了林分改造试验林108亩,示范林3900亩,试验林采用多因素正交法进行研究,经过栽培三年后的调查分析结果:柏林低效林分改造各试验组合的草本植物和灌木盖度比改造前增加16.7~33.3%和18.3~48.3%,乔木以桤木、柏木混义、中密度和培土的组合最佳;马尾松低效林分改造各试验组合的草本植物和灌木盖度增加36.7~53.3%和13.4~16.7%,乔木以马尾松、刺槐行带混交和中密度的组合最佳。由于经过改造的林地植被恢复快,土壤理化性质得到改善,土壤非毛管孔隙和总孔隙度增加,贮水能力明显提高。

Abstract: Adapting the polycross trial method, the author studied the lower-protection-function stands.Three years after planting, the herds'and shrub'coverages increased by 16.7-33.3% and 18.3~48.3% in the reforestde Cypress stands, The mixural, modrerate density and soiling block of Cypress wity Alder stand presents the best, while in the Horse-tail pine stands, the coverage by 36.7-75.3% and 13.4-16.7%, best in line-stripe cross and modcrate-density pine with Locust tree.The general trands are that the reforestation tria can recover the plants cover, improve the soil properties as to increase the pole percentage and water-hold capability.
