摘要:
市域尺度的生态功能分区对于市域生态资源的有效保护和合理利用起着不可替代的指导作用。现阶段较为被动而静态的功能分区研究忽视了市域生态资源在城镇化发展中的剧烈变化。而景观生态学的“源-汇”概念和相关手段,将区域生态功能空间格局与不断变化的生态过程之间建立了联系,在生态功能分区科学理性的研究实践中运用前景广阔。本研究运用景观生态学“源-汇”理论,以内蒙古通辽市为例,通过对于研究区域中“源”景观的划分,设定不同景观要素的阻力值,构建基于“源”动态特征的最小累计阻力模型,计算得出阻力面。并进一步通过寻找阻力面突变点来确定分区阈值,最终确定通辽市域尺度生态功能的5大分区,并提出有针对性的分区管控措施与指引。研究将市域生态要素在城市化下的动态演变与生态安全格局进行有机关联并制定科学的分区策略,为市域生态空间的优化及管理提供了理论依据。
Abstract:
Green Space of Municipal Administrative Area ecological function zoning is irreplaceable for the effective protection and rational utilization of the urban ecological resources.The ecological function zoning of resources at this stage is passive and static were ignored in the dramatic changes in the development of urbanization.The source-sink landscape theory of landscape ecology and the prospect of its related methods, Establishes the relation between the regional ecological function space pattern and the changing ecological process.,are widely used in the study and practice of scientific rationality in the ecological function zoning. this is a case of Tongliao of Inner Mongolia studyon the basis of source-sink landscape theory, through the study on the division of "source" landscape in the area, set different resistance values of the landscape elements, build the MCR model based on the dynamic characteristic of the source model, the surface resistance is calculated. And mutation point by looking for surface resistance to determine the threshold value division, ultimately determine the Tongliao Green space of municipal administrative area ecological function of five partitions, and put forward targeted partition controls and guidance. Research provides a theoretical basis for optimization of regional ecological green space layout and management of the organic relation and formulate scientific and partition strategy under the urbanization of the dynamic evolution and ecological security pattern will reach the green space landscape elements.
