【摘要】 近年来,世界上许多国家对生态系统服务功能的研究十分重视。人们已经认识到,生态系统服务功能是人类生存与发展的基础,它为人类提供了持续、可观的各类产品和各种可见或不可见的服务。随着对可持续发展机制研究的深入,人们发现维持与保护生态系统服务功能是实现可持续发展的基础,分析与评价生态系统服务功能价值已经成为当前研究的前沿课题。本文以安徽省为研究区域,对该区域内的多种生态系统的服务功能进行了价值估算;分析生态系统服务载体(土地)的结构特征;进而探讨安徽省生态系统服务的总体特征及其区域分异状况。具体内容如下:论文以Costanza等的核算方法为基础,结合安徽省的实际情况进行适当修正,对安徽省生态价值现状进行核算,1996年安徽省生态系统服务功能总价值为1425.036×108元,为同期该省国民生产总值的60.92%,低于全国以及全球平均水平,属于生态价值亏损区;水域、有林地、农田是安徽省最为主要的生态服务类型,3者总共提供的生态价值为1176.175×108元,占总价值的82.54%。安徽省平均生态系统服务强度为10169.69元/公顷,淮北平原地区及江淮丘陵地区属于低生态服务强度地区,沿江平原区的芜湖和马鞍山属中生态服务强度区;皖西山地岗区、皖南山区及铜陵市属高生态服务强度区。安徽省土地利用的结构存在着较大差异。由北向南:均衡性渐强、集中性渐弱,土地利用程度逐渐降低;由东向西:均衡性渐强、集中性渐弱,土地利用程度逐渐升高;且南北变化更为明显。根据土地利用结构及生态系统服务功能特征,可以将安徽省17个地级市分为5个区域:淮北平原生态区、江淮丘陵岗地生态区、皖西山地生态区、沿江平原生态区、皖南山地丘陵生态区。论文分析了安徽省生态建设中面临的主要问题,根据有关生态学原理,提出了提高安徽省生态系统服务功能及实现自然资源的可持续利用的建议和对策。更多还原

【Abstract】 In recent years, the studies on ecosystem service are taken into account. It has been recognized that the ecosystem service is the basis of human survival and development, and provides for mankind sustained, substantial various types of products and services that are visible or invisible. With the in-depth studies of mechanisms for sustainable development, it was found that the maintenance and protection of ecosystem services are the foundation for achieving sustainable development. People have been studying the meaning and valuating methods by different ways and pushing it to be an advances ecological issue.The paper accesses the ecosystem service of Anhui Province and analyzes the Land Use Structure (LUS), and then probe further into characteristics of ecosystem service of different regions in Anhui Province. The main contents are as follows:Base on the theories and methods of valuating the ecosystem service and natural capital, combined with the conditions of Anhui Province, the indices and parameters were proposed and the current values were calculated. The total value of Anhui Province’s ecosystem services was 1425.036×108 yuan in 1996, accounting for 60.92 percent of GDP in the same period, which was lower than the national and global average level and was a loss zone of ecological value. Waters, woodlands, far mlands are the most major ecological service types in Anhui Province. The value of those three is 1176.175×108 yuan, 82.54 percent of Anhui Province’s value. The average intensity of Anhui Province’s ecosystem services is 10169.69 yuan per hectare. Huaibei plain and Jianghuai upland and flatland belong to zones of low ecological services intensity; the cities of Wuhu and Ma an Shan in the Yangtze-river plain area are medium ecological service intensity; Wanxi Mountain zone, Wannan Mountain and Hill zone and Tong ling city maintained high ecological service intensity.Regional difference in Anhui Province is evident.
