Construction of county ecological-human integrated corridor based on MSPA and suitability evaluation:taking Pucheng County in Shaanxi Province as an example
Ecological-human corridors can organically combine human elements and natural landscapes,pro-vide green recreational routes for people,and enhance the cultural connotation and social value of the region.This study takes Pucheng County,Shaanxi Province as the study area,adopts morphological spatial pattern a-nalysis(MSPA)and landscape connectivity analysis methods,superimposes ecosystem service value evalu-ation and habitat quality evaluation to identify ecological source areas,and utilizes the current model to ex-tract ecological corridors and pinch points to construct an ecological network in the study area;based on the results of the evaluation of human corridor appropriateness,extracts potential human corridors,and combines them with ecological corridors to form an ecological-human integrated corridor,and proposes an ecological-human integrated corridor to protect biodiversity and promote biodiversity conservation,human corridors,and propose construction strategies.The results show that:there are 27 ecological source sites in the study area,with a total area of 265.20km2,mainly distributed in the northwest;49 ecological corri-dors,with a total length of 168.16 km,are distributed in a network structure in the northwest,and some of them are connected with some of the source sites in the south and the east in a longer path.There are 19 human corridors,which are distributed along the main roads and in an arc shape in the area of dense cul-tural and tourism spots;this paper proposes a spatial pattern of ecological and human corridors of"one corridor,one ring and two belts",which can help to explore the construction method of corridors for har-monious coexistence between human beings and nature,and to promote the regional ecological integration and comprehensive and high-quality development.
