Effects of Land Use Transition on Ecosystem Service Values in Wuling Mountain Region in Chongqing City
[Objective] The effects of land use transition on ecosystem service values (ESV) in the Wulong District were analyzed in order to provide a basis for decision-making regarding rational land use
optimal allocation of resources
development and protection
and maximization of ESV in the Wuling Mountain region.[Methods] Based on land use data for the Wulong District in 2010
2015
and 2020
the effects of land use transition on ecosystem service values in the Wulong District were calculated. The spatial-temporal changes of land use transition on ecosystem service values were analyzed by using a land use transfer matrix
a change contribution rate model
and a cross-sensitivity coefficient.[Results] ① In 2020
high values of ESV in the Wulong District were concentrated in Xiannvshan Street and Baima Town in the middle of the Wulong District
while the low-value areas were concentrated on the east and west sides of the Wulong District and Tukan Town in the middle. ② From 2010 to 2020
the ESV in the Wulong District showed an increasing trend; ③ From 2010 to 2020
ESV change and variation contribution rate of different land use types in the Wulong District consistently followed the order of forest>water>cropland>grassland>desert. ④ The sensitivity coefficient of converting grassland to forest land was the highest
while other land use types were not sensitive to the conversion to grassland.[Conclusion] The increase of forest land and water area can greatly increase the total ESV. We suggest increasing the area of garden land and forest land
and strictly controlling the abandonment of cultivated land during the time when adjustments are made to agricultural practices and structure.
