中文摘要:
      水系连通是水资源管理、水利建设的一项极其重要的内容。研究水系连通区的土地利用与生态服务价值变化具有重要意义。以济南西部多水源连通(黄河、长江、玉符河、小清河、玉清湖水库)交汇区为研究对象,基于遥感影像解译数据,定量分析1988-2014年研究区水系连通过程中土地利用转型及其对生态环境的影响。结果表明:1988-2014年,济西多水源连通交汇区林地、耕地和建设用地分别减少了7.76、3.26和4.77 km2,水域和草地分别增加了9.77和6.03 km2;研究区土地利用转型经历了以林地转化为主导和以耕地转化为主导的两个阶段,前一阶段土地利用的稳定性较差,后一阶段土地利用的稳定性有所提升;1988-2014年,研究区生态服务价值由9.04×108元增至15.01×108元,说明当地生态质量不断提高,生态系统逐渐趋于复杂。济西湿地是研究区生态质量提高的关键,湿地的修复与建设既是水系连通的成果,又是水系连通的保障。
英文摘要:
      Water system connection is a crucial part of water resources management and water conservancy construction. It is of great significance to study the changes of land use and ecosystem service value in the confluent area of water systems. Taking the confluent area of multi-resources (the Yellow River, Yangtze River, Yufu River, Xiaoqing River and Yuqing Lake Reservoir) in western Jinan as the study area, and based on the interpreted data derived from TM & OLI images, we quantitatively analyzed the transformation of land use and its impact on the environment of the region, which occurred in the process of river system connection during 1988 - 2014. Results show that during the period of 1988-2014, forest land, arable land and construction land in the study area were decreased by 7.76 km2, 3.26 km2 and 4.77 km2 respectively, whereas water area and grassland were increased by 9.77 km2 and 6.03 km2 respectively. The land use transformation in the study area is divided into two phases, which are forest-transformation dominant phase and farmland-transformation dominant phase, with the land use being less stable in the former phase. During the period of 1988-2014, the ecosystem service value in the study area increased from 0.904×109 to 1.5×109 yuan, indicating that the local ecological quality had been improving and the ecosystem was becoming more complicated. The preservation of the wetland is the key to improving the ecological quality of the study area. The restoration and construction of the wetland is the achievement of water system connection, and in turn the wetland maintains the connectivity of the water systems.
