干旱区土地利用转化的碳储量响应及脆弱性研究
A Study of Carbon Storage Response and Vulnerability of Land Use Transformation in Arid Area:taking Ningxia as an Example
摘要
Abstract
Land use transformation is a behavioral choice of human economic transformation and ecological transformation,and there are differences in the response of ecological service value and function under different choices.Exploring the response mechanism and vulnerability of land use transformation and carbon storage services in arid areas under the goals of"carbon peak"and"carbon neutrality"is an urgent issue to be addressed in the spatial governance and joint action of welfare and ecological civilization construction.This study takes four counties in the central arid zone of Ningxia as the research unit,and analyzes the mechanism and vulnerability of land use transformation and carbon storage response over the past 20 years using the InVEST model.The research has shown that:(1)The intensity of land conversion has increased over the past 20 years,with grassland being the main source of land conversion,which has been converted into arable land and construction land;farmland and construction land are mainly transferred in.(2)The spatial distribution of carbon storage response has been highly consistent with the transformation of land use types.The conversion of grasslands to construction land is the main reason for the decrease in carbon storage,and the distribution of carbon storage shows a pattern of"high in the northeast and low in the southwest";(3)In the past 20 years,the land use index has increased by 5.03,and the PI index has shown negative potential impacts.In the early stage,the vulnerability was relatively high,but in the later stage,the vulnerability improved and the resilience increased.Therefore,it is necessary to strengthen the planning of land use transformation,emphasize the coordinated development of economy and ecology,in order to achieve the construction and development of a human land community in arid and ecologically fragile areas.关键词
