| Abstract: | A quantitative analysis of the characteristics of ecosystem changes in key areas of biodiversity protection on the Loess Plateau from 2013 to 2018 was carried out,using geo-information and ecological remote sensing interpretation technology.The results showed that:the ecosystem structure of the research area was relatively simple,mainly three class of Ⅰ ecosystems(forest-shrub,grassland,farmland)and five dry land class of Ⅱ-level ecosystems(deciduous broad-leaved forest,deciduous broad-leaved shrub,warm grassland,grassland).During the study period,the rate of change of the area of all types of ecosystems,the degree of comprehensive dynamic and landscape index changes were not significant,the overall performance of the ecosystem pattern is stable;the dominant factors of the various types of ecological landscape pattern changes were the social environment,the implementation of forest,grass and other ecological environmental protection. |
