Construction of ecological security pattern in Loess Plateau counties by integrating structural connectivity and functional enhancement: A case study of Ansai District, Yan'an City, Northwest China.

Ecological security pattern is an important spatial way to maintain ecological processes and ensure the stability of ecosystem functions. As the implementation of landscape planning and decision-making, it is critically needed to consider the consistency of differentiated methods and their spatial outputs in the construction of ecological security patterns and the matching and applicability of research objects. From the perspective of integration, we combined the regional topography and landscape characteristics, integrated the morphological spatial pattern analysis and the importance evaluation results of ecosystem services to identify the ecological source, and constructed the ecological security pattern of the Ansai District of Yan'an City, the main implementation area of the Grain-for-Green Project on the Loess Plateau.

Urban ecological security pattern construction coupled with risk and service: A case study of Xianyang City, Shaanxi Province, China.

How to combine regional ecological risks and local ecological needs to construct ecological security is one of the main issues of its application in territorial spatial governance and associated with whether it can be effectively applied. Based on the "source" accessibility and the quality of space, we constructed the ecological security pattern of Xianyang City through the way of source-corridor-node. During the construction processes, we combined the cha-racteristics of topography, influencing factors of regional ecological security, and landscape characteristics.
