干旱区草型湖泊湿地价值量化评估

Evaluation of Grass Type Lakes Wetland Value

本文以典型干旱区草型湖泊鸟梁素海湿地为研究区，在实地调查和试验的基础上，依据资源经济学和生态经济学的理论和方法，针对鸟梁索海湿地资源的特点．对鸟梁素海湿地的价值进行了货币化评估。评估结果表明，乌梁索海湿地的总价值为28．24×10^8元，其中直接实物产品价值为7164．70×10^4元．直接非实物服务价值为18195．43×10^4元．间接价值为81960＋58×10^4元，日前非使用类价值为17．51×10^8元。只有合理开发鸟梁素海湿地资源，保护好这一对区域环境具有重要意义的干旱区湿地生态系统，才能实现鸟梁素海湿地资源的可持续利用．保证湖区经济的可持续发展。

Based on the grass type lakes wetland resources＇s character, the economics theory and method is applied in the paper on the base of the investigation and experiment to analyses the asset value type of the wetland resources and to evaluate the values in Wuliangsuhai lake wetland. Researching value, travel consumption method, Robert Constanza method, market value method, assets value method, Contingent Valuation Method. The conclusion can be drawn that the total assets value of the Wuliangsuhai lake wetland is RMB 2.824 billion yuan （US$0.352 million）. The direct use value is RMB 253.58 million yuan （US$31.69 million）. The indirect use value is RMB 819.60 million yuan （US$102.44 million）. The current non-use value is RMB 1.75 billion yuan （US$0.22 billion）. Only when we make use of the wetland resources rationally and protect the wetland ecoenvironment and carry out the assets management of the wetland resources in Wuliangsuhai lake wetland, can the sustainable utilization of the wetland resources be realized and the sustainable development of the regional economy around Wuliangsuhai lake wetland is guaranteed.
