The economic valuation of environmental resources is of great interest to society in general and to public managers in particular. It can promote more sustainable environmental policies, as it clearly shows the high economic value of natural resources. Thus, these valuation tools can provide useful evidence to support such policies by quantifying the economic value associated with the protection of such resources. However, there is an inherent difficulty in the implementation of methods to assess the economic valuation of environmental resources, mainly as a result of the absence of a market and hence a price that explains its social demand. However, both the travel cost method and the contingent valuation method used in this paper offer an approach to the economic values of the recreational services for wetlands. The aim is to analyze whether these values have been influenced by the economic crisis, so two time periods are compared separated for a decade. Results do not show an unequivocal influence between values in both periods, with different behaviors among natural areas, although with a certain tendency to increase in the decade being analyzed.
环境资源的经济估值通常受到社会的广泛关注，特别是受到公共管理者的关注。它可以促进更可持续的环境政策，因为它清楚地表明了自然资源的高经济价值。因此，这些估值工具可以通过量化与保护这些资源相关的经济价值，为支持这些政策提供有用的证据。然而，在实施评估环境资源经济价值的方法时存在内在的困难，主要是由于缺乏市场和因此无法解释其社会需求的价格。然而，本文中使用的旅行成本法和条件价值法为湿地娱乐服务的经济价值提供了一种方法。目的是分析这些价值是否受到经济危机的影响，因此比较了两个相隔十年的时间段。结果并没有显示出两个时期的价值之间存在明确的影响，不同的自然区域有不同的行为，尽管在分析的十年中存在一定的增长趋势。
