河南省沿黄地市生态环境质量时空演变及驱动因子分析
Spatial-Temporal Evolution and Driving Factors Analysis of Ecological Environment Quality Along the Yellow River in Henan Province
摘要
Abstract
The natural ecological background of the Yellow River Basin is fragile.Long-term human development and construction activities have led to habitat fragmentation and biodiversity reduction.The Landsat remote sensing image data of 2000,2010 and 2020 were selected to calculate four indicators of greenness,humidity,dryness and heat to build remote sensing ecological index(RSEI).The RSEI was used to evaluate spatial-temporal evolution characteristics and trends of ecological environment quality in 8 cities and counties(districts)along the main stream of the Yellow River in Henan Province,and geographic detector was used to analyze its driving factors.The results indicate that a)the average RSEI in the study area from 2000 to 2020 is 0.731 1,and the overall ecological environment quality is above the middle level.Lingbao City and Zhengzhou City have poor ecological environment quality,while Xin'an County and Mengjin District have good ecological environment quality.b)Over the past 20 years,the ecological environment quality has first been deteriorated and then improved,and most of the areas show an overall improvement trend.The improvement of ecological environment quality in the lower reaches is better than that in the middle reaches.c)The single factor detection results indicate that the driving factors that characterize human activities,such as land use types and GDP,gradually enhance their impact on the quality of the ecological environment.The results of multi factor interaction detection indicate that there is a strong interaction between GDP,land use type and population density with other factors.关键词
