| 摘要: |
| 通过对黄土高原可持续发展评价指标体系和方法的初步研究,设计出了包括1个高级综合指标--可持续发展综合指数、人口状况等5个基本指标和人口自然增长率等30个元素指标的层次性指标体系结构框架,熵技术支持下确定可持续发展指标权重的层次分析法,以及由递阶多层次综合评价、主成份分析和回归分析等数学方法所集成的可持续发展全面综合评价模型,并以陕北黄土高原为例进行了具体的应用分析与评价。 |

| Abstract: |
| The technology of film-mulched and bunch-seeding cultivatio is an effective way to accomplish top quality,high and stable yield of dryland wheat.The experiment results indicate that yield of film-mulched and bunc-seeding wheat is colsely related with soil moisture before sowing.Therefore,the application of this technology should be adjusted according to rainfall during summer fallow and soil moisture before sowing.It may be used in the years with rich rainfall during summer fallow and with good soil moisture condition,yet in the years with inadequte rainfall and poor moisture condition,it may cause increase in production but decrease in income. |
