潍坊市北部咸/卤水区土地利用及其生态系统服务价值变化分析研究

运用遥感和GIS技术获取潍坊市北部咸/卤水区1983年-2013年间4期土地利用数据,分析了研究区研究时段土地利用变化及生态系统服务价值变化状况.结果表明:1983年-2013年间,潍坊市北部咸/卤水区裸地和潮滩面积不断缩小,建设用地和盐田面积不断增加;总的生态服务价值量从1983年的174.46 亿元减小到2013年的137.07 亿元,降幅达21.43%,主要是由于具有较高生态服务价值的潮滩等用地类型持续减少所致.应限制盐田和建设用地等的过快增长,并注重保护沿海潮滩湿地.

Analysis of Ecosystem Services Value Dynamics in Salt-brine GroundwaterDistribution Area Based on Land Use Change of Northern Weifang

The land use map of salt-brine groundwater distribution area in northern Weifang in 1983,1995,2004 and 2013 was acquired by using technologies of RS and GIS.Based on the land use maps, land use and ecosystem service valuechange was studied.The results indicate that with the transformation of bare land and tidal flat to construction land and saltpan, the ecosystem service value loses 3.74 billion yuan during 1983-2013 which accounts for 21.43% of the total ecosystem service value in 1983.The land use change affects the regional ecosystem service value apparently, so some relative measure such as restriction of quick growth of saltpan and construction land, maintenance of tidal flat and water body should be adopted to prevent the decline of ecosystem service value in salt-brine groundwater distribution area in northern Weifang.
