克里雅河流域地表径流与景观格局相关性分析
Correlation Analysis of Surface Runoff and Landscape Pattern in the Keriya River Basin
摘要
Abstract
In this study,we explored the relationship between changes in surface runoff and changes in landscape pattern in the Keriya River basin,aiming to provide a technical reference for protecting the ecology of the basin.Based on land use/land cover(LULC)data for the study area in five periods(1980,1990,2000,2010,and 2020),we extracted landscape pattern index data at the levels of type and land-scape.The effects of surface runoff on landscape pattern were then analyzed using ArcGIS and Fragstats 4.2 software,and multi-disciplinary methods including landscape index calculation,Pearson correlation analysis,and Meta analysis.Results show that:(1)From 1980 to 2020,changes in land use type in the ba-sin were clear.Land use consisted primarily of unused land,grassland,and surface water.In 2020,the combined proportion of these three types accounted for 97.79％of the total area,with respective pro-portions of 75.17％,20.58％,and 2.04％.The areas of cultivated land and unused land increased by 331.64 km2 and 3 838.09 km2.respectively,while the areas of surface water and grassland decreased re-spectively,by 1 147.64 km2 and 2 955.13 km2.(2)The areas of three land use types(cultivated land,sur-face water,and unused land)correlated positively with basin runoff,while areas of the three other land use types(forest land,grassland,and construction land)were negatively correlated with basin runoff.At the landscape level,total edge length(TE),edge density(ED),and landscape shape index(LSI)were posi-tively correlated with basin runoff.Moreover,landscape fragmentation and landscape edge length trended upward during the study period.(3)Meta analysis further verified that basin surface runoff significantly impacted the landscape pattern at both the type level and landscape level.关键词
