摘要
为揭示并预测武陵山区土地利用与生境质量时空演变特征,基于2000、2010、2020年的土地利用数据,通过斑块生成土地利用模拟(patch-generating land use simulation,PLUS)模型和生态系统服务与权衡综合评估(integrated valuation of ecosystem services and trade-offs,InVEST)模型,模拟并分析武陵山区土地利用与生境质量时空演变特征。研究发现武陵山区主要地类为林地,耕地次之,2000-2020年土地利用变化呈“三减三增”的特点;2021-2030年土地利用变化将呈“一增多减”的特点,各地类的变化强度减弱。武陵山区生境质量较高且基本保持稳定,生境质量的高值区和低值区聚集分布;其中,高值区的生境是武陵山区的主要生境类型,不同生境质量等级的区域面积变化呈现“一增两减,两稳定”的特点。2000-2020年武陵山区中西部地区生境质量有所改善,北部和东南部的局部地区生境质量退化,2021-2030年生境质量整体将保持稳定。该研究可为武陵山区土地资源可持续利用和生境质量的提高提供科学依据和决策参考。
In order to reveal and predict the spatiotemporal evolution characteristics of land use and habitat quality in Wuling mountain area,the spatiotemporal evolution characteristics of land use and habitat quality in Wuling mountain area were simulated and analyzed by the patch-generating land use simulation(PLUS)model and the integrated valuation of ecosystem services and trade-offs(InVEST)model based on the land use data from 2000,2010,2020.It was found that the main land type in Wuling mountain area was forest land,followed by cultivated land,and the land use change in 2000-2020 showed the characteristics of″decrease an three aspects and increase in three aspects″.In 2021-2030,the land use change will be characterized by″increase in one aspect and decrease in more aspects″,and the intensity of change will weaken.The habitat quality in Wuling mountain area was high and basically stable,and the high-value and low-value areas habitat were clustered and distributed,and the high-value areas habitat was the main habitat type in Wuling mountain area,and the changes in the area of habitat quality grade show the characteristics of″increase in one aspect decrease in two aspects,and stability in two aspects″.In 2000-2020,the habitat quality in the central and western Wuling mountain area improved,while the habitat quality in the northern and southeastern area deteriorated,and the overall habitat quality will remain stable in 2021-2030.The results can provide a scientific basis and decision-making reference for the sustainable use of land resources and the improvement of habitat quality in Wuling mountain area.
