- Abstract:
-
The analysis of the temporal and spatial evolution and driving factors of the green space ecosystem service value(ESV)of Central Yunnan Urban Agglomeration is conducive to understanding the spatial differences of regional ecosystem services, helps planners master the natural resources of Central Yunnan Urban Agglomeration from the macro level, and reasonably formulates planning and construction strategies. Taking 49 districts, counties and cities of Central Yunnan Urban Agglomeration as research units, we quantified the ESV in three periods of 2000, 2010 and 2019, collected the driving factors of ‘nature society economy' dimension, and used principal component analysis and geographic weighted regression to explore the driving effect of ‘nature society economy' factors on the green space ESV of Central Yunnan Urban Agglomeration. The results show that:(1)from 2000 to 2019, the ESV of green space in Central Yunnan Urban Agglomeration generally increased; in the primary service types, the supply, support and cultural services increased slightly, and the regulation services decreased slightly; In the secondary service types, climate and hydrological regulation contributed the most to the ecosystem service function, followed by soil conservation, biodiversity and gas regulation;(2)the spatial distribution characteristics of ESV in the three phases were relatively consistent, showing that the ESV in the marginal area of urban agglomeration was higher than that in the central area of urban agglomeration;(3)social factors had the greatest impact on the temporal and spatial evolution of ESV in green space of urban agglomeration in Central Yunnan, followed by natural factors and economic factors; the main driving factors were urbanization rate, per capita GDP, population density, forest coverage and the proportion of secondary industry;(4)the urbanization rate, population density and the proportion of secondary industry showed the characteristics of two-level driving; per capita GDP showed negative driving characteristics; the forest coverage showed positive driving characteristics. In summary, the ESV of green space in the Central Yunnan Urban Agglomeration has increased in the last 20 years, and its changes are mainly influenced by social factors. This study can provide a reference for the sustainable development of the Central Yunnan Urban Agglomeration.
