A survey has been conducted on the connotations of ecological green cores and landscape functions, and a systematic review has been provided for the research contents and approaches concerning ecological green cores at home and abroad, with the approaches of the multi-functional regulation and its application being the research focus, thus pointing out a clear direction for the future multi-functional regulation of the landscape in ecological green cores. Such a goal can be achieved by an emphasis laid on the effects upon changes of landscape functions exerted by changes in landscape structures and variations of spatial patterns, followed by an exploration of landscape multi-functional responses from the perspective of regional multi-spatial scales, so as to build a landscape function regulation system under the scenario simulation model, improve the landscape multi-functional evaluation methods, update the data-based multi-functional landscape indexes to landscape function changes, optimize the multi-functional regulation and decision-making process of the landscape, simulate controlling measures, establish a dynamic monitoring mechanism, and strengthen the feasibility studies on landscape functions and their applications.
