城市化过程中海岸带景观异质性变化及其景观生态效应的初步研究--以厦门市马銮湾地区为例

以厦门马銮湾为研究区域,在分析景观异质性的基础上,采用地质统计学的理论和方法并结合GIS强大的空间分析和显示功能,通过一定的数学模型和生态效应分布图的表示方法,对快速城市化过程中区域景观异质性变化和由此导致的景观生态效应程度进行了定性和定量相结合的综合评估,结果表明,城市景观的同化过程是区域景观结构和景观异质性变化的主要表现,景观生态效应空间分布图也表明城市化对应的生态学过程的规模效应在整个规划区内有扩大的趋势.

Primary study on changes of landscape heterogeneity and landscape ecological effect: a case study of the Maluan Bay in Xiamen City

The changes of landscape heterogeneity in the process of rapid urbanization, together with their influence on the landscape ecological effect, were qualitatively and quantitatively analyzed in the Maluan Bay, Xiamen City.The geo-statistics theory and method combining with strong spatial analysis and display function of GIS were applied. Subsequently, the mathematical model and the spatial distribution of landscape ecological effect were also used to this research, based on the analysis of landscape heterogeneity. The result indicates that the main manifestation of landscape pattern and changes of landscape heterogeneity is process of assimilating of urban landscape. In addition, the dimensions and effect of ecological process corresponding to urbanization trends to extend in terms of the figure of landscape ecological effect.
