牧草与林木的间作在生产实践中早已采用,但研究报道甚少。为探讨林草间作在提高光能利用效率、发挥土地资源的生产潜力以及增加单位面积经济收益等方面的作用,笔者于1981-1983年在我区的一些基层场、站进行了调查研究。现将1982-1983年在阿拉善左旗治沙站的调研结果,报告如下。一、调查地区的自然概况调查地位于内蒙古自治区阿拉善左旗腰坝滩境内,地理位置为东经105°33′-34′,北纬38°26′-36′,处于贺兰山和腾格里沙漠之间。海拔高1,285-1,350米,地势平坦,东北部稍高。土壤为冲积淤积土,土层深厚肥沃,耕作 Forage grass and forest intercropping have long been used in production practice, but few reports have been reported. In order to explore the role of forest and grass intercropping in improving the utilization of light energy, exerting the productive potential of land resources and increasing economic benefits per unit area, the author carried out research in some grass-roots fields and stations in our district in 1981-1983. Now 1982-1983 alzherazuoqi sand control station survey results are reported below. I.
