摘要
基于河南省2015年地理国情普查数据和2019年基础性地理国情监测数据,分析了2015—2019年河南省沿黄区域8市1县的不同地表覆盖类型的分布格局及其变化特征,并计算了不同市县的人均生态承载力.此外,结合经济发展数据,分析了河南省沿黄区域8市1县的生态承载力变化与经济发展之间的关系.通过研究发现,河南省沿黄区域8市1县的种植土地、林地覆盖和房屋建筑(区)的面积占比相对较大,2015—2019年河南省沿黄区域的种植土地、林草覆盖、荒漠与裸露地的面积整体呈减少趋势,房屋建筑(区)、道路、构筑物、人工堆掘地和水域的面积整体呈增加趋势.8市1县中,三门峡市的人均生态承载力最高,2015年和2019年分别为0.756 hm^(2)/人和0.753 hm^(2)/人,郑州市的人均生态承载力最低,2015年和2019年分别为0.193 hm^(2)/人和0.173 hm^(2)/人.除滑县外,2015—2019年河南省沿黄区域其他市县的人均生态承载力均呈下降趋势.通过分析河南省沿黄区域8市1县的人均生态承载力现状及人均生态承载力的变化与经济发展的关系可知,滑县、济源市和三门峡市的经济发展的可持续性相对较好.
Based on the 2015 survey data and 2019 basic monitoring data of Henan province national geoinformation,this study analyzed the distribution pattern and the change characteristics of different land coverage types in 8 cities and 1 county along the Yellow River in Henan Province from 2015 to 2019,and calculated the per capita ecological carrying capacity of different cities and counties.Meanwhile,combined with economic development data,the study analyzed the relationship between ecological carrying capacity changes and economic development of the region along the Yellow River in Henan Province.The results showed that the area of planted land,woodland and housing construction land in different cities and counties along the Yellow River region accounted for a relatively large proportion.During 2015 to 2019,the area of planted land,forest and grass cover,deserts and bare land showed a decreased trend overall,and the area of housing construction land,roads,structures,artificial land and waters showed a increased trend overall.Among the 8 cities and 1 county,Sanmenxia had the highest per capita ecological carrying capacity at 0.756 hectares per person in 2015 and 0.753 hectares per person in 2019,and Zhengzhou had the lowest per capita ecological carrying capacity at 0.193 hectares per person in 2015 and 0.173 hectares per person in 2019.Except Hua County,the per capita ecological carrying capacity of all cities and counties along the Yellow River showed a downward trend during 2015 to 2019.From the perspective of per capita ecological carrying capacity and per capita GDP change ratio and per capita ecological carrying capacity status,the sustainability of economical development in Hua County,Jiyuan City and Sanmenxia City was relatively higher than that of other cities and counties along the Yellow River.
