Analysis of changes in ecological service functions and driving factors in Sandagu Nature Reserve
摘要
Abstract
Taking Sandagu Nature Reserve as a research topic,from the perspective of functional zoning of nature reserves,special attention was paid to the spatiotemporal changes of land use and ecological service functions,and the carbon storage and biodiversity maintenance function of the region was evaluated and analyzed by using the InVEST model.And the driving factors of the spatiotemporal variation were analyzed by using the geographic detector.The results showed that:(1)From 2000 to 2020,the land-use types in the studied area changed significantly,some grasslands in the middle and low altitude areas of the north were converted into woodland,and some woodlands in the high altitude areas were converted into grasslands;the glaciers melted in some areas of the northwest region and several scattered lakes were formed.(2)In 2000,2010,and 2020,the total carbon storage in the studied area was 7.349,7.348 and 7.151 Tg,respectively,unvaried in the first decade and then decreased.(3)From 2000 to 2020,the habitat quality in the studied area were maintained at a good level,and the overall habitat quality first increased and then stabilized.(4)From 2000 to 2020,the spatial differentiation of the ecological service functions in the studied area was mainly affected by elevation,rainfall,soil and vegetation cover index,among which elevation and vegetation cover indices had the most significant impact.The effect of the interaction between various factors was stronger than that of a single factor,and the strongest synergy occurred between the elevation and vegetation cover indices type(more than 0.7).The ecological service functions of the studied area were good,of which the northwest region was greatly enhanced,while the woodland area was decreased slightly,and the changes in the area near the glacier were relatively complex.关键词
