摘要
土地利用变化会引起区域生态环境的一系列响应.以重庆市为研究区,参照国内外的研究成果,根据重庆市2001—2006年的土地利用情况,综合运用景观生态学理论和生态服务价值理论,从土地利用结构变化出发,以生态系统的复杂性和稳定性为前提,测算重庆市近6年来生态服务价值的变化.研究表明重庆市2001—2006年期间生态系统服务功能年度经济价值量变化呈现上升趋势,土地利用结构调整方向总体来说是基本合理的,土地利用生态效益明显.
Regional eco-environment responds to land use change. This article takes Chongqing for the study area. In the light of domestic and foreign research results and according to land use in Chongqing from 2001 to 2006, it applies landscape ecology theory and ecological services value theory comprehensively. From land use structure change, it calculates ecological services value of Chongqing city on the premise of ecosystem complexity and stability. The study indicates that the economic value change of ecosystem services per year is on the rise. The land use structural adjustment direction is reasonable on the whole while the ecological benefits of land use change are obvious.
