| 摘 要： | 目的]根据谢高地生态系统服务功能价值体系,对奇台绿洲荒漠交错带生态系统服务功能价值进行评估.在价值评估的基础上,以不同类型土地面积变化为基础,探讨生态系统服务功能价值的变化趋势及变化原因,并进一步讨论价值变化与土地面积变化之间的关系,在此基础上提出干旱区绿洲生态系统可持续发展的对策提供数据支持.方法]研究采用谢高地生态服务价值体系评价奇台绿洲荒漠交错带在1986～2005年间生态系统服务功能价值,并在此基础上对该地区景观格局时空变化进行分析.结果]奇台绿洲荒漠交错带生态系统服务功能价值明显呈现出逐年递减的趋势;谢高地生态服务价值体系计算结果降低的趋势线斜率为-0.100 8.结论]通过转移概率矩阵来分析生态服务价值的变化,造成生态服务价值下降的原因主要是林地和草地面积减小,而农田和城市面积增大.人为活动对研究区景观格局产生的影响, 已成为生态环境退化的主要驱动因子和因素.

| Abstract: | Objective and Method]This study adopted Xiegaodi eosystem services value system to assess ecosystem service values from 1986 to 2005 in Qitai oasis and desert criss-cross zone to analyse the change of space time of the landscape pattern in this area.Result]The results showed that.The functional value of ecosystem service in oasis and desert criss-cross zone in Qitai region were significantly decreased year by year.The trend line slanting rate of service value system in Xiegaodi was-0.100 8.Conclusion]The probabality transfer matrix was used to analyse the change of ecosystem service values,and the ecological service value came down because of reduce of forest and grassland area.Moreover the area of farm and city was increased,man-made activity interfered landscape pattern of this study which were the main factors causing the devolntion of ecological environment. |
