基于InVEST模型的宁夏地区生境质量时空演变特征
Spatial-temporal evolution characteristics of habitat quality in Ningxia based on InVEST model
摘要
Abstract
Based on the land use change data of Ningxia in 2000,2010 and 2020,the InVEST model and ArcGIS software were used to analyze the spatial-temporal evolution characteristics and influencing factors of land use type and habitat quality.The results showed that:On account of various factors,the change trend during 20 years is that cultivated land,grassland and bare land are reduced,while forest land,water body and urban land are increased.The overall habitat quality level in Ningxia remains at a moderate level between 20 years.The areas with high habitat quality are concentrated in quality are concentrated in the main urban areas of each city.It shows a trend of degradation due to rapid urbanization,dense population,high road hardening,low greening rate and high traffic accessibility,and related policies and measures.There is a significant correlation between land use type and the evolution of habitat quality.关键词
