河南省生态环境质量的时空演变特征及驱动力分析
Spatio-temporal Evolution Characteristics and Driving Force Analysis of Ecological Environment Quality in Henan Province
摘要
Abstract
As a core area of the ecological protection and high-quality development strategy in the Yellow River Basin and the water source of the Middle Route of the South-to-North Water Diversion project,Henan Province plays an important role in national ecological security.It is of great significance to study the evolution characteristics and driving mechanisms of ecological environment quality.Using ecological environment quality datasets from 2001 to 2021,along with Theil-Sen median trend analysis,the Mann-Kendall test,the Hurst index,and a geographical detector,this study systematically revealed the spatiotemporal evolution characteristics and driving mechanisms of ecological environment quality in Henan Province.The results showed that 1)during the study period,the average ecological environment quality of the province was 0.46,showing an overall upward trend with fluctuations.The ecological environment quality was moderate in most areas.The ecological environment quality in Funiu and Dabie Mountains continued to be at a level higher than good,the ecological environment quality in southern Zhumadian,Nanyang,and Xinyang gradually changed from poor to moderate,while the ecological environment quality in northern Luoyang and Zhengzhou changed from moderate to poor.2)From the perspective of the change trend,the majority of the study area remained relatively stable,while 19.58%exhibited improvement trends,and 16.69%showed degradation trends.3)In the future,49.25%of the regions might experience ecological improvement,whereas 50.75%might face the risk of ecological degradation.4)Gross primary productivity and land use were the main factors affecting the ecological environment quality of the study area,and their interactions with factors such as GDP,precipitation,temperature,population,elevation,and slope significantly enhanced the explanatory power of spatial variation.The results provide a scientific foundation for ecological environmental protection in Henan Province.关键词
