摘要
小浪底水库作为改造自然的人类工程之一,对小浪底库区周围的环境变化影响明显。该文采用小浪底库区的土地利用的栅格数据,利用转移矩阵,从空间和时间上对小浪底库区的土地利用变化进行了分析。文章以采用多种评估方法,计算了小浪底库区的生态系统服务价值,并通过权衡协同度,从空间上对库区生态系统服务价值的变化进行了评估,为合理利用土地提供理论指导。结果表明:(1)小浪底库区以耕地为主,耕地、草地面积呈消减趋势,其他类型用地面积增加,动态度变化较大。(2)济源市耕地、草地以转出为主。洛阳市只有耕地以转出为主。三门峡市中林地、草地及耕地以转出为主,运城市林地和水域以转入为主,其他利用方式以转出为主。(3)库区的生态系统服务价值方面:小浪底库区生态系统服务价值整体呈增长趋势,但增长率逐年下降。供给服务功能、调节服务功能中,水域的贡献率突出。(4)这4个市2000年以供给服务功能为主,2005年以后以调节服务功能这为主,文化服务功能有增长的趋势。生态系统服务功能之间以协同关系为主,个别市供给服务与调节服务功能、支持服务功能呈权衡矛盾关系。
Xiaolangdi Reservoir,as one of the human projects to transform the nature,has exerted a considerable influence on the environmental vicissitudes in the Reservoir’s surrounding area.In this paper,the raster data of the land-use in the Reservoir area and the transfer matrix were applied to the analysis of the land-use changes in the Reservoir area in terms of space and time.Several evaluation methods were used to calculate the ecosystem service value of the Reservoir area,and by weighing the degree of coordination,the changes in the ecosystem service value of the reservoir area were evaluated spatially,thus providing theoretical guidance for the rational use of land.The findings Showed that Xiaolangdi Reservoir area is dominated by arable land,however the areas of arable land and grassland are in decline,and the areas of other types of land have been on the rise,and the dynamic degree has changed greatly.Among the cities in the area,Jiyuan City’s land-use change is mainly the transfer-out of arable land and grassland,Luoyang City’s arable land has been decreasing,and in Sanmenxia City,the main transferred-out land being forest,grassland and arable land,while in Yuncheng City,the land-use change being the transferred-in of forest land and area of waters,and other lands being transferred-out.As to the ecosystem service value of the reservoir area,the overall value of system services has been increasing,but the growth rate is in decline year by year;the contribution rate of water area is outstanding in so far as the supply service and atmosphere regulation service.The four cities were characterized by supply service function in 2000,and the atmosphere regulation service being the main function after 2005;and the cultural services function tend to increase.The ecosystem service functions mainly feature being synergistic,and the supply services in some cities feature a kind of trade-off and contradictory relation about the functions of atmospheric regulation and support services.
