【摘要】：生态系统服务功能价值评估是通过经济学方法,将湿地生态系统服务功能价值以货币化的形式度量化、直接化和可视化的过程。本文研究对象为海南东寨港红树林自然保护区典型滨海湿地和海南滨海湿地生态系统,以查阅相关资料为基础,通过对2012年LandsatTM遥感影像进行解译,结合实地调查数据和海南省第二次湿地资源调查报告,进行湿地类型划分。东寨港滨海湿地生态系统包括红树林沼泽、滩涂、养殖塘和河口水域4个类型;海南主岛滨海湿地包含10个类型,分别为浅海水域、砂石海岸、岩石海岸、潮下水生层、珊瑚礁、红树林、河口水域、淤泥质海滩、三角洲(沙洲/沙岛)和海岸性咸水湖。重点计算了东寨港红树林生态系统的碳储量及价值、海南省滨海湿地中的潮下水生层、红树林、河口水域、淤泥质海滩、三角洲和海岸性咸水湖6个生态系统的碳储量及价值。在此基础上建立了滨海湿地生态系统服务功能评价体系,选出了树木年材积生长量价值、养殖捕捞价值、防风消浪蓄水调洪价值、水质净化价值、大气调节价值、固碳价值、有害生物控制价值、生物多样性价值、促淤造陆保持养分价值、休闲游憩价值和科研教育价值11项服务功能。采用市场价值法、生产价值法、替代工程法、费用支出法和碳税法等评价各项生态系统服务功能,对其价值进行评估,结果表明:(1)东寨港红树林湿地植被碳密度为95.97t·hm~(-2),碳储量为148658.12t;土壤碳密度为170.4t·hm~(-2),碳储量为276770.23t,总固碳量425428.35t,总碳储量价值40330.61万元。(2)海南滨海湿地植被碳储量296390.61t;土壤碳密度207.72t·hm~(-2),碳储量4347152.65t;总碳密度221.89 t·hm~(-2),总碳储量4643543.256t;总碳储量价值439773.71万元。(3)东寨港红树林湿地生态系统服务价值总价值为47136.32万元·a~(-1),其主导服务价值为防风消浪蓄水调洪价值、促淤造陆和保持土壤养份价值、休闲游憩价值,价值量分别为15753.59万元·a~(-1)、9975.45万元·a~(-1)和5296.80万元·a~(-1),占总价值量的比例分别为33.42%、21.16%和11.24%。(4)海南主岛滨海自然湿地生态服务功能总价值为969426.42万元·a~(-1),主导服务功能是休闲游憩价值、养殖捕捞价值、防风消浪蓄水调洪价值、科研教育价值和生物多样性价值,其价值量分别为298468.28万元·a~(-1)、181336.30万元·a~(-1)、157616.68万元·a~(-1)、143138.19万元·a~(-1)和98357.85万元·a~(-1);占总价值量的比例分别为30.79%、18.71%、16.26%、14.77%和10.15%。通过对海南东寨港红树林滨海湿地和海南主岛滨海湿地生态系统的服务功能进行价值评估,解释了其主导服务功能,为进一步提高红树林保护区的管理能力以及公众对滨海湿地生态系统功能和价值的认识提供科学依据。同时,对海南主岛碳储量和生态系统服务功能的价值评估,填补海南省滨海湿地价值评估的空白,可为生态补偿机制提供参考数据。
[Abstract]:The value assessment of ecosystem service function is through the method of economics, the form of quantification of wetland ecosystem services value in the process of monetization, direct and visualization. The object of this study is the coastal wetland ecosystem area of typical coastal wetland in Hainan Mangrove Nature Reserve and Hainan, access to the relevant data as the foundation, through the on 2012 LandsatTM remote sensing image interpretation, according to the report of the survey data in Hainan province and second wetland resources, wetland types. The ecosystem of coastal wetlands including Hong Kong Dongzhai mangrove swamps, beaches, ponds and estuarine waters of 4 types of coastal wetlands in Hainan; the main island contains 10 types, respectively in shallow waters. Sand, coast, rock coast, tidal water layer, coral reefs, mangroves, estuaries, silt beach, Delta (sand sand island) and coastal lagoons. The key to calculate the carbon storage and the value of mangrove ecosystems, coastal wetlands in Hainan Province in the tidal water layer, mangroves, estuaries, silt beach, carbon storage and the value of delta and the coast of Salt Lake in 6 ecological systems. Based on the established evaluation system of waterfront wetland ecosystem the service function, selected trees volume growth value, value of farming and fishing, wind wave flood water, water purification, gas regulation value, the value of carbon sequestration, pest control value, the value of biodiversity, siltation epeirogenic nutrient conservation value, recreational value and scientific research value of education service function 11 using the market value method, production value method, substitute engineering method, cost method and carbon tax evaluation of the ecosystem service function, evaluation, the results show that: (1) the value of mangrove wet The vegetation carbon density of 95.97t - hm~ (-2), carbon storage is 148658.12t; soil carbon density of 170.4t - hm~ (-2), carbon storage is 276770.23t, the total amount of carbon sequestration of 425428.35t, total carbon reserves value 403 million 306 thousand and 100 yuan. (2) Hainan coastal wetland vegetation carbon reserves of 296390.61t; 207.72t - hm~ (soil carbon density -2), the carbon storage of 4347152.65t; the total carbon density of 221.89 T - hm~ (-2), total carbon reserves of 4643543.256t; total carbon reserves value 4 billion 397 million 737 thousand and 100 yuan. (3) the total value of mangrove wetland ecosystem service value is 471 million 363 thousand and 200 yuan a~ (-1), the leading service value for wind wave flood water the value of silt land reclamation to promote and maintain the soil nutrient value, recreational value, the value is 157 million 535 thousand and 900 yuan respectively, 99 million 754 thousand and 500 yuan, a~ (-1) - a~ (-1) and a~ (-1) 52 million 968 thousand yuan, accounting for the proportion of the total value were 33.42%, 21.16% and 11.24%. (4) the main island of Hainan Binhai the natural wetland ecological service The total value of 9 billion 694 million 264 thousand and 200 yuan for the service function of a~ (-1), the leading service function is the recreational value, the value of farming and fishing, wind wave flood water scientific research value, educational value and the value of biodiversity and its value were 2 billion 984 million 682 thousand and 800 yuan, 1 billion 813 million 363 thousand yuan, a~ (-1) - a~ (-1), 1 billion 576 million 166 thousand and 800 yuan - a~ (-1), a~ (-1) 1 billion 431 million 381 thousand and 900 yuan and 983 million 578 thousand and 500 yuan a~ (-1); the proportion of the total value were 30.79%, 18.71%, 16.26%, 14.77% and 10.15%. were used to assess the value through the service functions of the coastal wetland in Hainan mangrove wetland ecosystem and the main island of Hainan. Explain the leading service function, to provide scientific basis for further improving the mangrove reserve management capabilities and the public awareness of the function and value of wetland ecological system. At the same time, to assess the value of the main island of Hainan and the carbon storage of ecosystem services, fill in The blank of the value assessment of coastal wetland in Hainan province can provide reference data for the ecological compensation mechanism.
