备注

基于Meta分析的价值转移方法构建各种土地利用类型生态系统服务价值数据库,建立林地、草地、耕地、水域和未利用地5种土地利用类型的生态系统服务价值回归模型。并以长白山地区的延边州为例估算1996年、2006年、2016年的生态系统服务价值。结果 表明:(1)文章所建立的价值转移模型在以往研究成果的基础上,增加社会经济方面中的人口密度和人均GDP等因素,推动了研究区生态系统服务价值的变化分析;(2)利用Meta价值转移模型估算的延边州1996年、2006年、2016年的生态系统服务总价值的趋势为先减后增。根据不同土地利用类型相互间的变化,总结出延边州空间生态系统服务价值的分布规律,结果呈现为西北部高,中部地区较低的格局;(3)伴随时间的推移,在各土地利用类型总面积减少14 780 hm2的情况下,延边州总生态系统服务转移价值得到增加。因此,合理规划生态类型用地的格局,对延边州未来的生态建设具有重要的意义。运用数据统计的方法,使得对研究区不同生态系统类型的相互影响联系更加密切,从而为生态系统的发展和生态文明的建设以及延边州区域可持续发展提供决策建议。

Based on the meta-analysis value transfer method, a database of ecosystem service value of various land use types is constructed, and a regression model of ecosystem service value of 5 land use types of forest land, grassland, cultivated land, water area and unused land is established. The values of ecosystem services of Yanbian Prefecture in Changbai Mountain in 1996, 2006 and 2016 were estimated. The results show that:(1)the population density and GDP per capita in socio-economic aspects were added in the value transfer model established based on previous research results in this paper, which promoted the analysis of changes in the value of ecosystem services in the study area;(2)the trend of total values of ecosystem services in Yanbian Prefecture estimated using the Meta Value Transfer Model in 1996, 2006, and 2016 decreased at first and increased later; according to the changes of different land use types, the distribution pattern of the space ecosystem service value in Yanbian Prefecture was summarized, and the results showed a pattern of high value in the northwest and low value in the central area;(3)over the time, in each land use type with the total area reduced by 14 780 hm2, the transfer value of total ecosystem service in Yanbian Prefecture increased; therefore, rationally planning the pattern of ecological land use is of great significance to the future ecological construction in Yanbian Prefecture. The results show that the use of data statistics makes the interaction between different types of ecosystems in the study area closer, so as to provide decision-making recommendations for the development of ecosystems and the construction of ecological civilization, as well as the sustainable development of Yanbian Prefecture.
