Abstract:
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—2015 the wetland area reduced 113.2 km2,agricultural land area decreased 941.2 km2,open space area reduced 269.4 km2,construction land and forest area increased by 1 298.9 km2 and 24.9 km2.Total assets of the corresponding ecological changes were -11.6×108 RMB,-10.6×108 RMB,-0.18×108 RMB,0.89×108 RMB,0.89×108 RMB,the overall ecological services Hangjiahu total assets reduced by Plain Area of 20.6×108 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.
