- 摘要:
- 水是影响黄土高原地区刺槐生长的主要因子.分析表明陇东黄土高原为壑区南小河沟流域4种主要立地条件类型中,沟坡刺槐林的现实生产力已接近气候生产力,阴山坡为气候生产力的60.11%,阳山坡仅为气候生产力的2.5%.因此,营造山坡刺槐林时,应注意水分资源的有效利用,大力推广径流林业造林技术,以提高刺槐林生产力.
- Abstract:
- Water is a main factor affecting locust growth.The analysis results pointed out,the practical productivity of locust forest in gully slope land approached climate productivity,it in sunless slope land was 60.11% of climate productivity,and it in sunny slope land only was 2.5% of climate productivity.Hereby,water resources sufficient use was prompted in planting slope locust forest,meanwhile,the culture technology of runoff-forest should gain to spread so as to increase locust forest productivity.
