Remote Sensing Monitoring and Thermal Environment Response Analysis of Land Use / Cover Change in Changping District, Beijing

Abstract:

As a rapid developing area, Changping in Beijing, China, the change of land use and land cover(LUCC) had occurred at large scale in the recent 20 years. Remote sensing had provided the approach to monitoring LUCC and the environment response. The paper focus on monitoring LUCC and quantitative analysis of the thermal environment response. Based on the multi-temporal LandsatETM remote sensing images in 1999 and 2006, the earth surface brightness tempreture had been obtained by retrieving from LandsatTM6. The regional land use change and its spatio-temporal thermal environment evolution were analyzed with ENVI4.7 and Arc GIS 9.2. The research results showed that the land use changed evidently from 1999 to 2006. The regional urban expanding and the spatio-temporal thermal environment evolution was consistent from 1999 to 2006. By comparing the contrbution from the different land use types to the urban thermal environment effect, it was discovered that forest land was the largest contributor for the low area. The proportion of forest land decreased in the low temperature areas, and the proportion of urban land increased in high temperature area from 1999 to 2006. The urban heat island effect was obvious. The nakes arable land resulted the high temperature areas. The forest land and the agricultural land with the crop was helpful for the lower temperature areas.
