喀斯特槽谷区土地利用转型过程对生态系统服务价值的影响
|
摘要
揭示当前多因素驱动下喀斯特槽谷区典型地貌单元土地利用转型过程的生态系统服务价值影响具有重要意义。以2005年、2010年、2014年、2017年高清影像为数据源并结合实地调研对解译数据进行了对比验证,借鉴国内外生态系统服务价值最新研究成果,结合研究区实际情况对生态系统服务价值系数进行了修订,通过对土地利用转移矩阵分析和生态系统服务价值指标计算。结果表明:(1)研究区内草地、灌木林地、山地旱地、有林地、农村居民用地、城镇用地变化显著,山地旱地转为草地、城镇、农村居民用地,草地转为有林地、灌木林地。(2) 2005—2010年土地利用转型山坡较槽坝显著。2010—2014年土地利用转型主要集中于槽坝,山地旱地转为农村居民用地、城镇用地,水田转为农村居民用地,草地转为山地旱地。2014—2017年土地利用在山坡—槽坝同时发生转型。(3)喀斯特槽谷区生态系统服务价值在2005年、2010年、2014年、2017年分别为129 825.44万元、134 744.99万元、102 592.28万元、102 816.77万元。2005—2010年喀斯特槽谷区(ESV)由129 825.43万元变为134 744.98万元,增幅为1.85%;2010—2014年ESV由134 744.99万元变为102 592.28万元,下降了13.55%;2014—2017年ESV由102 592.28万元变为102 816.77万元,下降了0.11%;2005—2017年喀斯特槽谷区生态系统服务价值(ESV)由129 825.43万元变为102 816.77万元,总体下降了11.61%。
It is greatly significance to identify the effect of land use transformation process on ecosystem service value in typical topography unit of karst valley area driven by various influence factors. The ecosystem service value(ESV) coefficient of the study area was revised by using the high-resolution images from 2005, 2010, 2014 and 2017 as the data source, combining with field survey to verify the image, and the latest research results of ecosystem services value at domestic and abroad, according to the actual situation of the study area. The ecosystem service values were calculated through the analysis of land use transfer matrix and ecosystem service value index. The results are as followings.(1) The changes of grassland, shrub woodland, hilly dry land, woodland, rural residential land and urban land were significant in the study area; hilly dry land was converted into grassland, town and residential land, grassland was converted into woodland and shrubbery land.(2) During the period from 2005 to 2010, land use transformation in the trough basin area presented more obvious than the hillside. In the period from 2010 to 2014, land use transformation mainly concentrated in the basin, the hilly dryland was converted into residential land and urban land, and the paddy fields were converted into residential land, the grassland was converted into hilly dry land. In the period from 2014 to 2017, land use transitions occurred simultaneously in the hillside-through basin.(3) The ecosystem services values in 2005, 2010, 2014 and 2017 were 2.293 813 million yuan, 2.179 908 million yuan, 1.857 092 1 million yuan and 1.844 274 1 million yuan, respectively. In 2005—2010, the ESV changed from 1.298 254 3 million yuan to 1.347 449 8 million yuan, increased by 1.85%. In 2010—2014, the ESV changed from 1.347 449 9 million yuan to 1.025 922 8 million yuan, dropped by 13.55%. In 2014—2017, the ESV changed from 1.025 922 8 million yuan to1.028 167 7 million yuan, dropped by 0.11%. During the 12 years from 2005 to 2017, the ecosystem service value(ESV) in karst trough valley area changed from 1.298 254 3 million yuan to1.028 167 7 million yuan, dropped by 11.61%.
