| 摘 要： | 为揭示边境地区土地利用转型对生态服务功能的影响,推动区域生态环境与社会经济高质量发展。基于广西边境地区2000年、2010年、2018年3期土地利用遥感监测数据,识别18年间土地利用转型和生态系统服务价值的动态演变过程,结合改进的交叉敏感性系数探讨了广西边境地区生态系统服务价值对土地利用转型的敏感性程度。结果表明:(1)2000—2018年广西边境地区土地转型前期平缓,后期剧烈,耕地向建设用地、水域的转移是主要的转型驱动因素;(2)2000—2018年ESV呈现出先增后减的态势,地均ESV高值主要集中于防城区、宁明县南部以及那坡县南部生态环境本底优越的一带,地均ESV低值出现在宁明县北部、龙州县、大新县以及靖西市的中心城区生态系统较为薄弱的岩溶地区;(3)耕地、林地、水域与其他地类相互转型对生态系统服务功能影响较为敏感,其中最敏感的是林地与建设用地的转型,草地、未利用地与其他地类的转型缺乏敏感性。(4)生态敏感性空间演化分异特征显著,耕地与建设用地高生态敏感性重点分布在东兴市、宁明县、龙州县、靖西市,林地与建设用地高生态敏感区主要分布在防城区和东兴市主城区、凭祥市以及靖西市北部等重要的贸易出口通道。研究结果可为优化边境国土空间格局,实现生态服务功能的提升提供科学指引。

| 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. |
