浙江省杭嘉湖平原生态资产评估研究
|
摘要
杭嘉湖平原作为浙江北部城市发展的核心区域,欲在城镇快速发展的大背景下探究区域生态服务价值的变化状况,定量分析该区的生态服务价值变化状况,现通过对下载自美国地质勘探局的1974、1983、1995、2002、2015年5个时期遥感影像,对41年的影像进行分类,分析杭嘉湖平原地区的土地覆被的变化(LUCC)。结果表明:1974—2015年湿地面积减少113.2km~2,农业用地面积减少941.2km~2,空地面积减少269.4km~2,建设用地和林地面积分别增加1 298.9、24.9km~2。相应的生态资产总量变化分别为-11.6、-10.6、-0.18、0.89、0.89亿元,杭嘉湖平原区生态服务资产总额总体减少了20.6亿元。因此生态用地的大量被侵占对地区生态服务价值的提升极为不利,主要是地区经济的发展和人为的开发程度提高导致区域内的生态服务价值不断递减,其中研究区内湿地与农业生态用地大量减少是主要原因,今后在开发利用过程中应对区内生态用地进行科学适当合理的利用与保护。
Hangjiahu Plain is north of Zhejiang Province as the core area of urban development,want to explore in the context of the rapid development of urban regional ecological service value change in status,quantitative analysis of the ecological value of the area changes in the health service.By downloading from the United States Geological Survey 1974,1983,1995,2002,2015,five remote sensing images,the image of the 41 years analysis to classify land cover changes in Hangjiahu Plain area was the(LUCC),mainly conclusions were 1974—2015the wetland area reduced 113.2km~2,agricultural land area decreased 941.2km~2,open space area reduced 269.4km~2,construction land and forest area increased by 1 298.9km~2 and 24.9km~2.Total assets of the corresponding ecological changes were-11.6×10~8 RMB,-10.6×10~8 RMB,-0.18×10~8 RMB,0.89×10~8 RMB,0.89×10~8 RMB,the overall ecological services Hangjiahu total assets reduced by Plain Area of 20.6×10~8 RMB.Therefore,a large number of occupation on the value of ecosystem services areas to enhance the ecological land was extremely unfavorable,mainly regional economic development and human development which would lead to the value of ecosystem services within the region diminishing wetlands significantly reduce the agricultural ecological land where the study area.It was the main reason,in the future to deal with ecological land area in the process of development and utilization of appropriate scientific and reasonable utilization and protection.
