摘要
地处内陆干旱区的张掖黑河湿地国家级自然保护区是西北典型的内陆河流湿地生态系统,其调温增湿的气候调节功能是湿地重要的生态功能之一。根据保护区湿地周围3个气象观测点的数据,分析了其调温效应,并通过计算保护区湿地年水汽蒸发和植被蒸腾量,得出每年气候调节功能的价值为3.29亿元;表明保护区湿地在该区域的气候调节中发挥了至关重要的作用,而直观的货币价值为正确评价湿地改善小气候的能力、湿地的保护和开发及可持续利用提供科学的依据。
Located in the inland of arid region of northwestern China,the Heihe Wetland National Nature Reserve of Zhangye is a typical ecological system of inland river wetland.Its climatic regulation function is one of the important services of wetland ecosystem.The temperature regulation effect of the reserve was analyzed according to the observation data from meteorological stations around the reserve.It was concluded that the value of temperature regulation of the reserve was 329 million Yuan RMB from the calculation of moisture evaporation and vegetation transpiration within the reserve.The results showed that the reserve played a crucial role in climatic regulation in arid region.The monetary value provides a scientific basis for the correct evaluation of the ability of improving the microclimate as well as the conservation and reasonable development of the region.
