摘　　要：在四川盆地通过引进国内外薪材树种和选择乡土薪材树种,进行栽植密度、始伐年龄、轮伐期等试验研究,结果表明:从引进的8个新材树种中,选择出任豆为适宜生长的树种,新银合欢、黑荆、荆为为适宜部分地区生长的树种;从13个乡土薪材树(草)种中筛选出桤木、刺槐、麻栎、栓皮栎、马桑、卵花甜茅等为比较优良的薪材树(草)种。桤木、刺槐、马桑等薪炭林的合理造林密度为10000株(丛)/ha;麻栎、栓皮栎为6000～7000株(丛)/ha;印花甜茅以行距1m为宜。桤木、刺槐、麻栎、栓皮栎等薪炭林,始伐年龄不超过5年,轮供期3～6年;马桑薪炭林始伐年龄为3～4年,轮伐期2～3年、印花甜茅栽植1年后平茬,以后每年采收。合理的造林密度、始伐年龄、轮伐期,能使选择的几个树种提高生物产量1.0～2.5倍。Through experiments on introduction of fuelwood species abroad and at home and selection of native fuelwood species in the Sichuan Basin researches were conducted on their planting density, first felling age and rotation. The results have shown that,among 8 introduced species, Zenia insignis is a suitable species for growing in the Sichuan Basin while Leucaena leucocephala cv. 'Salvador' , Acaciasii and A. dealbata are only suitde for growing in part of regions,-among 13 native species,Alms cremas-togyne, Robinia pseudoacia,Quercus acutissima, Q. vaTiabilis,Coriaria sinica,Glyceria tonglensis are comparatively fine fuelwood species. The rational density of fuelwood forest of A. cremastogyne, R. pseudoacia and C. sinica is 10,000 stems/ha while that for Q. acutissima and Q. variabilis ranges form 6,000 to 7,000 stems/ha. And 1 meter spacing between rows is fit for G. tongletisis. For fuelwood forests of A. cremastogyne, R. pseudoacia, Q. acutissima and Q. variabilis, their first felling age is not more than 5 years,with a rotation of 3 to 6 years. The first felling age of C. sinica fuelwood forest is 3 to 4 years with a rotation of 2 to 3 years. G. tonglensis should be stumped a year after planting and then harvested every year. The rationality in planting density,first felling age and rotation will enable some selected species to increase their biomass by 1 to 2. 5 times.
