Study on ecological function zoning in the Municipal Administrative Area based on the landscape ecology source-sink theory: a case study of Tongliao, Inner Mongolia
摘要
Abstract
The Green Space of the Municipal Administrative Area ecological function zone is irreplaceable for the effective protection and rational utilization of urban ecological resources.The ecological function zoning of resources is passive presently and static,and the dramatic changes in the development and urbanization have largely been ignored.The sourcesink landscape theory of landscape ecology and its related methods,which establish relationships between the regional ecological function space pattern and changing ecological process,are widely used in the study and practice of the scientific basis of ecological function zoning.We used Tongliao,in Inner Mongolia as a case study based on the source-sink landscape theory through the study of the division of " source" landscapes in the area;different resistance values of the landscape elements were set,a minimum cumulative resistance (MCR) model was built based on the dynamic characteristic of the source model,and surface resistance was calculated.Based on surface resistance,a mutation point was established to determine the threshold values for landscape division,and thereby ultimately determine the most effective Tongliao Green Space municipal administrative area based on the ecological function of five partitions,and targeted partition controls and guidance were put forward.This study provides a theoretical basis for the optimization of regional ecological green space layouts and management of the ecosystem and formulates a scientific partition strategy that takes into account urbanization and dynamic evolution;we believe that implementing these recommendations will benefit green space landscape elements.关键词
