基于InVEST模型的洱海流域生境质量时空演变研究
Spatial and Temporal Evolution of Habitat Quality in Erhai Lake Basin Based on In VEST Model
摘要
Abstract
Taking Erhai Lake Basin as the research area,based on the land use change data from 2005 to 2020,this study used the InVEST model to explore the spatial and temporal distribution of habitat quality and habitat degradation in the Erhai Lake Basin.Combined with the Moran's I index to analyze the aggregation char-acteristics of habitat quality.The results showed that during the study period,the transfer of land use types in the Erhai Lake Basin is mainly manifested in the transformation of various types of non construction land to construc-tion land,as well as the mutual transformation of forest land,grassland,and cultivated land.The habitat degrada-tion degree of Erhai Lake Basin gradually decreased in 4 periods of 2005,2010,2015,and 2020,the habitat qual-ity indexes were 0.681 0,0.6809,0.6786 and 0.6725.The overall habitat quality was good but showed a down-ward trend,with a decrease of 1.25％.The standard deviation increased from 0.2892 to 0.3040,indicating an ex-pansion of spatial differences in habitat quality.The habitat quality of Erhai Lake Basin has aggregation character-istics in spatial distribution.The Moran's I index decreased year by year,indicating a dispersed trend in spatial clustering of habitat quality.In the future,we should control the intensity of development and utilization,guide the tourism industry reasonably,reduce human interference with the ecological environment,and achieve sustain-able green and high-quality development.关键词
