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。
Water is a main factor affecting locust growth. The analysis results pointed out, thepractical productivity of locust forest in gully slope land approached climate productivity, it insunless slope land was 60. 11% of climate productivity, and it in sunny slope land only was2. 5% of climate productivity. Hereby, water resources sufficient use was prompted in plantingslope locust forest, meanwhile, the culture technology of runoff-forest should gain to spread soas to increase locust forest productivity.
