【摘要】：湿地淡水资源供给是一项重要的生态系统服务功能,主要包括城镇居民生活用水、工业(矿业)用水和农业用水三大部分。以2013年吉林省湿地淡水供给资源作为研究对象,采用市场价值法,进行省域尺度上与人类生活、工业生产等关系密切的淡水供给服务识别与核算,研究吉林省不同湿地类型和不同行政区的淡水资源供给量和淡水资源供给价值,分析其淡水资源供给的空间分布及其贡献率。结果表明,2013年吉林省湿地淡水资源供给总量为20.81×10~8m~3,其中湖泊湿地、河流湿地、人工湿地和沼泽湿地供给淡水量为8.06×10~8m~3、6.04×10~8m~3、4.00×10~8m~3和2.71×10~8m~3;核算吉林省湿地淡水资源供给总价值为83.84亿元/年,其中湖泊湿地占38.73%,河流湿地占29.01%,人工湿地占19.25%,而沼泽湿地所占比例最小,仅13.01%。在各组成城市中,湿地淡水资源供给价值以松原市最大,核算价值为26.28亿元/年,占总价值的31.34%;白山市最小,为2.6亿元/年,占总价值的3.11%。利用价值量化的方法表征淡水供给为吉林省发展提供的经济价值,对区域水资源优化配置、促使社会经济和生态环境协调发展以及湿地保护具有重要的理论和现实意义。
[Abstract]:The supply of wetland freshwater resources is an important ecosystem service function, which mainly includes three parts: water for urban residents, water for industry (mining) and water for agriculture. Taking the freshwater supply resources of Jilin wetland in 2013 as the research object, using the method of market value, the identification and accounting of freshwater supply services which are closely related to human life and industrial production in provincial scale are carried out. The supply and value of freshwater resources in different wetland types and administrative districts in Jilin Province were studied, and the spatial distribution and contribution rate of freshwater resources supply were analyzed. The results showed that the total supply of wetland freshwater resources in Jilin Province in 2013 was 20.81 脳 10 ~ (8) m ~ (3), of which the supply of lake wetland, river wetland, artificial wetland and marsh wetland was 8.06 脳 10 ~ (8) m ~ (3) C ~ (3) 6.04 脳 10 ~ (8) m ~ (-1) 10~8m~3 and 2.71 脳 10 ~ (8) m ~ (3) respectively, and the total value of freshwater supply in Jilin Province was 8.384 billion yuan / year. The proportion of lake wetland is 38.73, river wetland is 29.01, artificial wetland is 19.25 and marsh wetland is the smallest, only 13.01. The supply value of wetland freshwater resources is the largest in Songyuan city, accounting for 2.628 billion yuan / year, accounting for 31.34% of the total value, and the smallest value is 260 million yuan / year in Baishan City, which accounts for 3.11% of the total value. Using the method of value quantification to characterize the economic value of fresh water supply for the development of Jilin Province has important theoretical and practical significance for the optimal allocation of regional water resources, the coordinated development of social economy and ecological environment and the protection of wetland.
