Changes in the Supply and Demand of Ecosystem Services in the Urban Agglomeration Around Changsha-Zhuzhou-Xiangtan
摘要
Abstract
The exploration of the relationship between the supply and demand of ecosystem services(ESs)will help to promote the orderly development of regional natural resources and the management of the eco-logical environment.Based on multi-source data,this paper selected four ecosystem services,including car-bon storage,food supply,water supply and soil conservation,and used the InVEST model,ESDR,and the local indicators of spatial association to comparatively analyze the spatial and temporal changes in the sup-ply and demand of ESs and the spatial matching status of ESs in the Urban Agglomeration Around Chang-sha-Zhuzhou-Xiangtan in the years of 2000,2010 and 2020.The results showed that 1)the total supply of all ESs exceeded the total demand.The supply of carbon storage decreased,the supply of food,water and soil conservation increased,and the demand of the four ecosystem services maintained an overall increase.2)The supply and demand ratio of carbon storage decreased,the supply and demand ratio of water supply increased,and the supply and demand ratio of food supply and soil conservation remained basically un-changed.Carbon storage,food supply and water supply were in deficit in built-up areas of towns and cities and in surplus in other areas.The deficit area of the soil conservation service was concentrated in the Dongting Lake Plain.3)In addition to soil conservation,which was dominated by low-low spatial matc-hing,the spatial dislocation of carbon storage,food supply and water supply were prominent.The high-low spatial dislocation was mainly distributed in mountainous areas with good ecological base,and the low-high spatial dislocation was mainly distributed in urban areas.Combined with the results of ecosystem service supply and demand and autocorrelation analyses,suggestions are proposed for resource development and protec-tions:to comprehensively enhance the ecological capacity of the study area and protect the ecological environment.关键词
