Abstract
The continuous improvement of international protection awareness has dramatically increased the number of protection organizations and promoted various reserve-naming methods. However, the existing global natural reserves have either fully or partially overlapped, thereby allowing the same region to hold various international titles, resulting in serious issues, which are especially manifested in the boundary delimitation process of natural reserves. Therefore, delimiting the titles of reserve borders will become an enormous challenge in protected-area governance worldwide. This study conducted an in-depth investigation of the technical methods for delineating the spatial boundaries of natural reserves. Taking Jiangshan Nature Reserve in China as the case object, the Candidate Area–Natural background–Heritage Resource–Construction (C-NHC) framework was constructed, and the boundaries of the new reserves were delineated. This study has changed the status quo of the spatial overlap of the reserve through the quantitative evaluation of the conflict patches and the triple optimization of the boundary of the reserve. The area of the new reserve is 150.524 km2, which is 6.682 km2 larger than the original one. The original reserves are all included within the scope of the new one. This study provides guidance and new insights into the boundary delineation of integrated nature reserves worldwide.

This study proposes an evaluation index system for the integration and optimization of reserve boundaries on the basis of the Candidate Area–Natural background–Heritage Resource–Construction (C-NHC) framework; optimizes the boundaries of natural reserves on the basis of the characteristics of the resource background, heritage resource characteristics, and construction management conditions thrice; and establishes a set of identifiable and popularized technical framework for the demarcation of the boundaries of natural reserves that will exert an extensive influence on the in-depth analysis of the spatial pattern of natural reserves in the future, improvement of the planning and management, and overall promotion of the construction of natural reserves

Summary
Industrialization and urbanization continue to expand globally, along with the continuous development of the human society [1,2]. Natural reserves with multiple titles reflect the high value of environmental protection and sustainable development. The qualitativeanalyzed, evaluation results of competitiveness are divided into three categorie were clustered classified, andlow, the identified candidate areas for reserve designation namely high,and medium, and through the natural breakpoint method These divided areas are PIN and POUT, which refer to the. The average values sented by statistical charts, and the distribution of various land-use levels is illustrated b of each resource of PIN and POUT were calculated according to the graded background the spatial-distribution-map characteristics. Allto spots outside theappropriate original reserve reclassified two categories according the cla conflict of map the original mapcharacteristics, are merged tonamely generate the distribution tosified the similarity the and resource background potential protected maps and spots
