【摘要】：Land cover is the most evident landscape signal to characterize the influence of human activities on terrestrial ecosystems.Since the industrial revolution,the expansion of construction land has profoundly changed the status of land use coverage and changes.This study is proposed to reconstruct the spatial pattern of construction land(urban construction land and rural settlement land)for five historical periods over the past 200 years in Jiangsu Province with 200 m′200 m grids on the basis of quantitative estimation.Urban construction land is estimated based on data about city walls,four gates along walls,and other socio-economic factors.Rural settlement land is calculated based on the rural population and per capita housing allowance.The spatial pattern of historical construction land is simulated based on the distribution of modern construction land in 1985 with a quantitative-boundarysuitability control method and thorough consideration over connectivity of different land use types.The study concludes that:(1)the amount of construction land in Jiangsu Province is estimated at 963.46 km~2 in 1820,1043.46 km~2 in 1911,1672.40 km~2 in 1936,1980.34 km~2 in1952 and 10,687.20 km~2 in 1985;and(2)the spatial distribution of construction land features the great proclivity to water bodies and main roads and the strong polarization of existent residence.The results are verified directly and indirectly by applying the trend verification of construction land changes and patterns,the correlation analysis between rural settlement land and local arable land,and quantitative accuracy test of the reconstructed construction land to actual historical survey maps covering four sample regions in 1936.
[Abstract]:Land cover is the most evident landscape signal to characterize the influence of human activities on terrestrial ecosystems.Since the industrial solution to the expansion of construction land has has the the of land use coverage and changes.This study is proposed to reconstruct the the the construction land and settlement land)for land)for land)for settlement 42# land)for land)for land)for the past 200 years in Province Province Province with with with. The basis of quantitative estimation.Urban construction land is estimated based on data about city walls,four gates along walls,and other socio-economic factors.Rural settlement land is calculated based on the rural population and per capita housing allowance.The spatial pattern of historical construction land is simulated based on the distribution of modern construction land in 1985 with a quantitative-boundarysuitability control method and thorough consideration over connectivity of different land use types.The study concludes. That:(1)the amount of construction land in Jiangsu Province is estimated at 963.46 km~2 in 1820 1043.46 km~2 in 19111672.40 km~2 in 1936 1980.34 km~2 in1952 and 10,687.20 km~2 in 1985 distribution of construction land features great great proclivity to water water and and the the polarization of existent residence.The residence.The residence.The indirectly by applying indirectly trend verification of verification verification of trend 411# of #en460# patterns the correlation between between between. Rural settlement land and local arable land,and quantitative accuracy test of the reconstructed construction land to actual historical survey maps covering four sample regions in 1936.
