  本文的研究主要以呼伦贝尔盟草地建设项目为例，基于案例进行定量和比较分析，探讨草地建设项目在投资成本和营运成本的估价和处理、项目收益的估价、项目筹资方案的确定原则和项目财务评价指标与评价报表应用方面的特殊问题，得出如下结论：必须在成本估价时考虑牧草的更新所导致的固定投资；在进行成本估价时必须考虑由于牧草的更新和产出变化所导致的经营成本周期性的不同；多年生牧草在产出上的周期性变化不仅会导致成本上发生变化，也会导致项目新增收入的变化和与收入相关的成本间接发生变化；设计合情合理的筹资方案，有利于保证项目中的每一个子项目顺利执行；针对草地建设投资项目的特点，选择适用的财务评价报表和财务评价指标才能更科学地测算草地建设项目的财务效益。
