- Abstract:

In order to reveal the impact of land use transformation on ecological service function in border areas and promote the high-quality development of regional ecological environment and social economy, based on three periods of land use remote sensing monitoring data in border areas of Guangxi in 2000, 2010 and 2018, the dynamic evolution of land use transformation and ecosystem service values during 18 years were identified, and the degree of sensitivity of ecosystem service values to land use transformation in border areas of Guangxi was explored in combination with improved cross-sensitivity coefficients. The results show that:(1)land transformation in Guangxi border areas from 2000 to 2018 was flat in the early stage and dramatic in the late stage, and the transfer of arable land to construction land and water area was the main transformation driver;(2)the ecosystem service value showed a trend of increasing and then decreasing from 2000 to 2018, and the high values of land-average ecosystem service value mainly concentrated in Fangcheng District, southern Ningming County and the area with superior ecological background in the southern part of Napo County, while low values of land-average ecosystem service value occurred in the northern part of Ningming County, Longzhou County, Daxin County, and the central urban area of Jingxi City where the ecosystem was weaker in karst;(3)the mutual transformation of arable land, forest land, water area and other land types were sensitive to the impact of ecosystem service function, among which the most sensitive was the transformation between forest land and construction land, and the transformation between grassland, unused land and other land types lacked sensitivity;(4)the spatial evolutionary differentiation of ecological sensitivity was significant; the high ecological sensitivity of arable land and construction land mainly distributed in Dongxing City, Ningming County, Longzhou County and Jingxi City, and the high ecological sensitivity of forest land and construction land mainly distributed in Fangcheng District and the main urban area of Dongxing City, Pingxiang City, and the important trade export corridors in the northern part of Jingxi City. The results can provide scientific guidance for optimizing the spatial pattern of border territory and improving the ecological service function.
