大庆龙凤湿地重要物种栖息地功能价值估算

Assessment of the Habitat Value of the Important Species in Daqing Longfeng Wetlands

大庆湿地发育较成熟,资源和物种都比较丰富,具有重要的经济、社会和生态价值。大庆湿地主要分为自然湿地和人工湿地两大类型,在湿地中,物种栖息地的功能价值具有重要的意义,其评估结果可以为决策者提供经济价值评价尺度,有利于提高公众对重要物种栖息地的保护和认识。本文选择大庆龙凤湿地这一对区域生态环境具有重要意义的湿地系统作为研究对象,在分析湿地类型的基础上,对龙凤湿地物种栖息地的功能价值进行量化评估,目的在于把湿地生态系统提供的物种栖息地的功能价值用人们具有明显感知的货币形式表示出来,以促进对湿地全面系统的认识,从而为湿地及其资源的保护和研究提供依据。本文利用生态价值法初步估算物种栖息地的价值,结果表明,2004年大庆市发展阶段系数为0.58,研究区湿地生物栖息地功能价值为1 655.17万元,研究也进一步说明在社会发展的现阶段,保护湿地环境的重要性。

The wetland development in Daqing is more mature and rich in resources and species,which have important economic,social and ecological value.The wetlands in Daqing mainly include natural wetlands and artificial wetlands.The function value of the species habitat has critical meaning for wetlands.The evaluation results can be used for decision makers to provide economic value evaluation scale,to improve the awareness of the public to protect the habitat of important species.This article chooses the Longfeng wetlands in Daqing city as the research objects which are important to the regional ecological environment.On the basis of the analysis of wetland types,the function value of the Longfeng wetland species habitats was quantitatively evaluated.The purpose is to show the function value of the species habitat provided by the wetland ecological system in the form of currency,so people can have sensory awareness and improve the understanding of the comprehensive wetland system,which can also provide a basis for the protection of wetland and the resources herein and research.By using the ecological value method,the value of the species habitat was preliminarily estimated.The results showed that the development stage coefficient in Daqing is 0.58 in 2004,and the function value of the wetland species habitats in the study area is 16.5517 million yuan.The study further indicates that in the current stage of social development,it is very import to protect the environment of wetlands.
