摘  要:
通过对窟野河、秃尾河、孤山川流域主要乔、灌木水土保持林的随机抽样调查分析,建立了林分保存密度与郁闭度的相关模型,并以此模型为基础,结合当地水保林经营现状,提出该地区刺槐、柠条、沙柳、踏郎和花棒的造林密度(株或丛/hm~2)分别以2571、4000、2400、3000和3000较为合理。这样的造林密度,在该地区既有较好的水土保持效益,又有较高的经济效益。

摘  要:
Through the analysis of random sampling of major arbor and bush forest in the basins of Kuye, Tuwei and Gushanchuan river a cornelation model of crop density and degree of canopy was created. On the basis of this model and local situation of forest for soil conservation, the proper afforestation oleasity. (tree/hm2) of locust, Korshinkii, Salix mongolical, Hedysarm mongolicum, Hedysarm scoparium was 2571, 4000, 2400, 3000, 3000 respectively. With such densities, both higher benefit for soil conservation and higher economic benefit may be obtained.
