为确保经济的持续健康发展与生态环境的和谐共生,深入研究并评估该区域生态环境的可持续状态至关重要.借助净初级生产力(NPP)修正生态足迹模型,从生态可持续性、生态压力、自然资源利用效率等3个方面综合评估了珠江三角洲9个城市2000年至2020年的生态环境状态.结果表明:(1)珠江三角洲总研究区生态环境处于可持续状态,但出现持续降低的趋势.其中,珠海、中山一直处于不可持续状态,佛山、深圳、东莞由2000年的可持续状态变为2020年的不可持续状态.(2)珠江三角洲总研究区生态压力呈现中部高、外围低的分布态势.2000-2020年,生态压力最大的城市为东莞,最小的为惠州.(3)珠江三角洲总研究区及各城市的万元GDP生态足迹均呈现不同程度的降低趋势,表明区域资源利用效率越来越高.
Ecological sustainability assessment of Pearl River Delta urban agglomeration based on net primary productivity
To ensure the sustainable and healthy development of economy and the harmonious coexistence of ecological environment,it is very important to thoroughly study and evaluate the sustainable state of ecological environment in this region.With the help of net primary productivity(NPP)modified ecological footprint mod-el,the ecological environment status of nine cities in the Pearl River Delta from 2000 to 2020 was comprehen-sively calculated from three aspects:ecological sustainability,ecological pressure and natural resource utiliza-tion efficiency.The results show that:(1)The ecological environment of the total study area of the Pearl River Delta is in a sustainable state,but it shows a continuous decreasing trend.Among them,Zhuhai and Zhongshan have been in an unsustainable state,and Foshan,Shenzhen and Dongguan have changed from a sustainable state in 2000 to an unsustainable state in 2020.(2)The ecological pressure in the total study area of the Pearl River Delta shows a distribution trend of high in the middle and low in the periphery.From 2000 to 2020,Dongguan was the city with the greatest ecological pressure,and Huizhou was the smallest.(3)The ecological footprint of ten thousand Yuan GDP in the total study area of the Pearl River Delta and each city shows a de-creasing trend to varying degrees,indicating that the regional resource utilization efficiency is becoming more and more efficient.
