关于牧场退化和恢复问题的陈述往往得到技术性评价的支持，对资源养护或恢复的经济影响考虑有限。在试图将经济因素纳入分析的少数情况下，所采用的方法显然存在一些缺点。这有时会产生误导性的结果，并使不同的恢复技术的比较困难。本文探讨了几个重要的问题，在获得一个经济的角度来看，退化牧场的恢复。效益-成本分析的正式程序是作为一个合理的框架，这些活动的经济评价。该框架适用于，通过案例研究的方法，研究牧场恢复的几种技术的私人经济价值。然而，由于分析所依据的数据有限，结论是指示性的，而不是确定性的。讨论了与分析扩展有关的问题，以包括牧场恢复管理的社会评价。
Statements concerning rangeland degradation and restoration issues are often supported by technically oriented evaluations, with limited consideration of the economic implications of resource conservation or rehabilitation. In the few cases where an attempt has been made to incorporate economic elements into analyses, some shortcomings have been evident in the methodology adopted. This has sometimes produced misleading results, and has made comparisons of different restoration technologies difficult. This paper examines several issues that are important in obtaining an economic perspective on the restoration of degraded rangelands. The formal procedure of benefit-cost analysis is presented as a rational framework for the economic evaluation of such activities. The framework is applied, via a case study approach, to examine the private economic value of several technologies for rangeland restoration. However, because the analysis is based on limited data, the conclusion is indicative rather than definitive. Issues relevant to the extension of the analysis to encompass social evaluations of rangeland restoration management are canvassed.
