该文通过对使用Vetiver草(Vetiveria zizaniodes)进行水土保持的植物技术与使用地埂的规范做法相比较,探讨了这些技术措施的经济效果.此外,揭示了以Vetiver草为基础的水土保持技术系统的相对经济优点.本文由以下四部分组成:有关土壤保持投资的经济性和用于完成该分析的模型等概念问题的讨论;对使用资料给予的描述;对基本分析的结果按其特定的性质加以讨论,以及建立可能综合各种因素的模型,并进一步研究和发展的结论及建议.
The paper explores the economic effects of these technical measures by comparing plantation techniques for soil and water conservation using Vetiver grass (Vetiveria zizaniodes) with land use practices, and reveals the benefits of Vetiver grass-based soil and water conservation technology systems Of the relative economic advantages.This paper consists of the following four parts: the economics of soil conservation investment and the model used to complete the analysis of the conceptual issues such as discussion of the use of information to give a description of the basic analysis of the results of its specific nature To be discussed, and to establish models that could synthesize various factors and to further study and develop conclusions and recommendations.
