[Spatiotemporal Evolution of Land Use and Ecological Resilience and Construction of Ecological Zoning in Guiyang City].
摘要
, while the rest of the land area increased. Land use dynamics were relatively stable, with a slight decreasing trend in the average value of the degree of land use, spatially presenting a pattern of low values in the north and east and high values in the south and west. ② During the study period, the urban ecological resilience in Guiyang City showed an upward trend in urban resistance and resilience, while resilience showed a slightly fluctuating downward trend. The average value of urban ecological resilience increased from 0.32 to 0.35, and the low resilience area shrank from the south to the center of the city, with both its area and proportion decreasing. Meanwhile, the area of the high resilience area fluctuated slightly but showed an overall increase, and the proportions of the area of the lower, middle, and higher resilience areas were all greater than 20%. Spatially, the distribution was high in the north and east and low in the south and west. ③ The four-quadrant model divided the study area into four ecological zones: coordination, potential, risk, and control zones. The study area was dominated by the potential and control zones. Based on the characteristics of the zones, strategies are proposed to enhance the risk-resistant ability and improve the ecological resilience of Guiyang City.
