[目的] 分析东北农林交错区土地利用景观及其生态环境效应的变化特征
为区域内资源利用和生态环境保护提供科学依据. [方法] 采用景观生态学理论和3S技术等理论方法
以1991—2013年4个时间点的遥感影像为数据源
通过景观指数计算和模型分析
得到22 a间土地利用景观格局和生态服务价值的演变特征
并对其驱动力进行探讨. [结果] 在1991—2013年
景观指数普遍经历"V"或"Λ"型的变化过程
景观形状、多样性指数近几年不断下降
斑块平均面积、蔓延度、聚集度增加
景观破碎化程度减小
稳定性、多样性遭到破坏
生态服务总价值经历下降后
在2013年达到524 299.55万元
林地是研究区最大景观类型
对生态服务总价值贡献率在40%以上. [结论] 研究区近22 a间土地利用景观及生态服务价值变化剧烈
受人口增长、社会经济发展和国家政策导向的影响较大.
[Objective] The objective of this study is to investigate the characteristics of land use landscape and its eco-environmental effects in northeast agriculture and forestry interlaced zone in order to provide scientific basis for resource utilization and ecological environment protection. [Methods] Based on the method of landscape ecology and 3S technology
remote sensing images in 1991
2001
2007 and 2013 were used
and landscape index calculation and model analysis were employed to study the evolution of land use landscape pattern and ecological service value. The driving forces of land use landscape evolution were also investigated. [Results] During the period from 1991 to 2013
landscape indexes varied as a "V" or "Λ" shape. The landscape indexes and diversity indexes decreased
while patch average area
sprawl and contagion indexes increased. The landscape fragmentation decreased
and the stability and diversity of landscape were damaged. The total value of ecosystem services decreased initially
and then increased continuously and reached to 5 242 995.5 thousand yuan in 2013. Forest was the greatest landscape type
which contributed above 40% for the total value of ecosystem services. [Conclusion] Land-use landscape and the value of ecosystem services changed greatly in the study area during the past 22 year
and population increase
economic development and government policy were the main driving factors.
