甘肃省的宜林荒山荒地总面积据“四五”资源清查为3997,96万亩,另有灌木林地1953.43万亩。对这些宜林地的质量情况和灌木林地改造成乔木林的可行性,如能有一个数量的估计也就是对我省在发展林业上的土地潜力有多大,有了基本的数量概念,为今后在造林中选择最有生产力的树种,提出适当的育林措施,并预估将来的森林生产力,进而对森林的各种效
The total area of barren hills and wasteland in Gansu Province is 3997,960 mu, according to the “April-May” resource inventory, and 19,543,400 mu of shrubbery land. The feasibility of transforming the quality of shrubbery land into shrubbery land and the conversion of shrubbery into arboriculture should have a quantitative estimate of the potential of the province’s land for forestry development and a basic quantitative concept for the future Select the most productive tree species in afforestation, propose appropriate measures for afforestation, and predict future forest productivity, which in turn will affect forest productivity
