2001-2020年塔城地区草地健康时空变化特征及其驱动力分析
Spatiotemporal dynamics and driving forces of grassland health in Tacheng Prefecture from 2001 to 2020
摘要
Abstract
As an important agricultural and pastoral area,Tacheng Prefecture,Xinjiang,China requires an in-depth study of grassland health to support conservation efforts and grazing management.However,the long-term spatiotemporal dynamics of grassland health and its driving forces across different grassland types remain insuffi-ciently explored.This study constructs a"pressure-state-response"model using 15 indicators and employs spatial principal component analysis,the coefficient of variation,the Hurst index,spatial autocorrelation,and the geo-graphic detector method to evaluate the spatiotemporal dynamics of grassland health and its driving forces in-Tacheng Prefecture from 2001 to 2020.The results indicate that:(1)Temporally,the grassland health index in-Tacheng Prefecture exhibits a fluctuating downward trend.The warning and collapse levels show opposite trends,whereas the sub-healthy and healthy levels remain relatively stable.(2)Spatially,the multi-year average grassland health levels transition from sub-healthy to warning and collapse states from west to east.Most grassland types predominantly fall within the sub-healthy category.(3)Regarding future trends,grassland health in Tacheng Pre-fecture is expected to continue declining,particularly in Tacheng City,southern Emin County,and northern Hoboksar Mongolian Autonomous County.(4)In terms of driving factors,vegetation is the primary determinant of grassland health,and factor interactions enhance its effects more significantly than single factors.Human activ-ities and socio-economic factors also interact with vegetation,further influencing grassland health.These findings provide a theoretical basis and valuable reference for future grassland planning and management in Tacheng Pre-fecture.关键词
