This report is based on the research of the influence of land cover change on the city climate using remote sensing data. Data from two periods with a fifteen year interval was analyzed. The land cover classification of a plot of land 600m by 600m was analyzed at 225 weather stations. At 145 of the 225 points, there was no change in land cover. At the 80 points experiencing the greatest change, land cover tended to urbanize. As for the un-changed points, the average temperature inclination was 0.052 degrees Celsius per year, and at urbanized points, the average temperature inclination was 0.067 degrees Celsius per year. The relation between temperature inclination and urbanized index UI and normalized vegetation index NDVI was also analyzed. There is correlation with temperature inclination and UI and NDVI.
This paper is the effect of land cover changes on city climate using remote sensing data. Data from two different times over a fifteen year period were analyzed. Land cover was classified in units of about 600m by 600m in size at 314 weather observation points and the relationship to climate changes was analyzed. At 231 of the 314 points, there was no change in land cover. At 27 points, the land cover had an urbanization trend. At points with no change, the mean annual temperature gradient was 0.051°C per year, and at urbanized points, the mean annual temperature gradient was 0.061°C per year. It was also found that latitude and land cover have a large influence on the temperature gradient from the results of factor analysis done using type I quantification.
This report is based on the research of effect of land cover change on the city climate using remote sensing data. This also considered the geographical characteristic and wind environment. In analysis of the land cover, data from two different times over a fifteen year period were analyzed. Land cover was classified at 314 weather observation points and the relationship to climate changes was analyzed. At points with no change, the inclination of temperature was 0.051 per year and, at urbanized points, the inclination of temperature was 0.061 per year. From the results of factor analysis done using type quantification, it was also found that latitude and land cover have a large influence on the temperature rise. In the land cover, the case high proportion of artificial land cover" and "urbanization" influenced strongly to temperature rise.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
