摘要
基于2000—2020年武陵山片区土地利用数据,综合土地利用转移矩阵、生态系统服务价值、生态环境质量指数、用地类型转换生态贡献率、生态响应程度指数等方法,探究武陵山片区土地利用演变特征及其生态环境响应机制。结果表明,2000—2020年,武陵山片区生产空间面积逐年减少,生活空间面积持续增加,生态空间面积先增加后减少;2005—2010年土地利用动态度最大;2000—2020年,武陵山片区生态系统服务价值逐期上升,共增加237.22亿元,生态环境质量指数波动增长,整体增加0.003610,生态环境质量指数与生态系统服务价值对“三生”空间演变的响应具有协同性;耕地转换为林地、草地转化为林地是武陵山片区生态环境质量改善的主要原因,而林地转换为耕地、草地转换为耕地、林地转化为建设用地是生态环境质量恶化的主要原因。
Based on land use data in Wuling Mountain Area from 2000 to 2020,the land use transfer matrix,ecosystem service value,ecological environment quality index,ecological contribution rate of land use type conversion,ecological response index and other methods were integrated to explore the land use evolution characteristics and its ecological environment response mechanism in Wuling Mountain Area.The results showed that the production space area in Wuling Mountain Area decreased year by year,the living space area continued to increase,and the ecological space area increased and then decreased.The land use dynamics were the largest from 2005 to 2010.From 2000 to 2020,the value of ecosystem services in Wuling Mountain Area increased gradually,with a total increase of 23.722 billion yuan.The ecological environment quality index fluctuated and increased by 0.003610 as a whole.The response of the ecological environment quality index and ecosystem service value to the evolution of production-living-ecological space was synergistic.The conversion of cropland to forest land and grassland to forest land was the main reason for the improvement of ecological environment quality in Wuling Mountain Area,while the conversion of forest land to cropland,grassland to cropland,and forest land to construction land was the main reason for the deterioration of ecological environment quality.
