Analysis on Changes in Carbon Sequestration Capacity of the Yellow River Downstream Ecosystem in Dongying City in Shandong Province from 2001 to 2022
摘要
Abstract
Abstracr:Since the 21st century,the carbon sequestration capacity of the Yellow River Basin ecosystem has changed significantly due to climate change and human activities.Evaluating the carbon sequestration ca-pacity of the ecosystem in the Yellow River Basin is of great significance for promoting ecological protec-tion and high-quality development in the region.But the current related research is particularly insuffi-cient.In this paper,taking Dongying city in Shandong province in the lower reaches of the Yellow River as an example,based on a large amount of field sampling data,by using CEVSA-ES model,the carbon se-questration capacity of the ecosystem in the study area over the past 22 years has been simulated.On this basis,by using ArcGIS and ENVI softwares,and a linear trend analysis method,the spatiotemporal varia-tion trend of the carbon sequestration capacity of the ecosystem in the study area has been analyzed.It is indicated that the net ecosystem productivity in the central and southern parts of Dongying city has in-creased rapidly,while the growth in the northern and coastal areas is relatively slow.Over time,the over-all net ecosystem productivity shows an increasing trend.The total primary productivity has increased rap-idly in a small number of areas in the central and southern parts of Dongying city,while the growth in the northern and coastal areas is slow.The overall primary productivity has shown an increasing state.The e-cosystem respiration has grown rapidly in a small number of coastal and southern areas,while the ecosys-tem respiration in the central region has shown a decreasing trend.The overall ecosystem respiration has shown a downward trend.This result is of great significance for the analysis of changes in carbon seques-tration capacity of the ecosystem in the lower reaches of the Yellow River.关键词
