摘要
通过建立1 km高精度网格分辨率的生态环境质量指数(Ecological Quality Index,EQI)和人类活动强度指数(Human Activity Intensity Index,HAI),基于四象限法研究两者的时空变化特征及变化关系。结果表明,福建省近20年间HAI持续上升,EQI在20年来先降低后上升,高HAI主要分布在人口聚集沿海城市,高EQI地区主要分布在内陆山区。福建省大部分城镇和道路处于高HAI、低EQI的区间,山区林地处于低HAI、高EQI区间。近20年来高HAI、高EQI区域占比升高3%,人类活动和自然环境协调变化和冲突变化均占9%,冲突变化地区主要出现在城市人口密集地区,协调变化区域主要出现在城区外围,在城区内部也有零散分布。近10年相比前10年协调变化地区上升4%,冲突变化降低5%,说明福建省近10年的生态环境保护和治理措施取得一定成效,福建省人类活动与生态环境区域协调发展。
The Ecological Quality Index(EQI)and Human Activity Intensity Index(HAI)was established by using a 1-km high-precision grid resolution to analyze their temporal and spatial changes and interrelationships through the four-quadrant method.The results reveal that over the recent 20 years in Fujian Province,the HAI has steadily increased,while the EQI initially declined before rising.High HAI values are predominantly found in densely populated coastal cities,whereas high EQI values are mainly located in inland mountainous areas.Most urban areas and roads fall within the high HAI and low EQI range,while forested mountainous regions are characterized by low HAI and high EQI.Over the past 20 years,the proportion of regions with both high HAI and EQI has increased by 3%.Areas experiencing both coordinated and conflicting changes each account for 9%.Conflicting changes are primarily observed in densely populated urban areas,while coordinated changes are mainly found in the outskirts of urban areas,with some scattered within the cities.Comparing the last 10 years with the previous decade,there has been a 4%increase in coordinated change areas and a 5%decrease in conflicting change areas.This shift indicates the effectiveness of ecological protection and governance measures implemented in Fujian Province over the past decade.These results demonstrate the regional coordinated development between human activities and the ecological environment in Fujian Province.
