Evaluation of land cover and ecological change of Yongding Hakka Tulou World Heritage Protection Area using remote sensing image
摘要
Abstract
In this paper,Yongding District,where there are World Heritage Hakka Tulou and its Conservation Plan Area(Hugao region),were taken as the study area. With the purpose of analyzing the land cover and ecological environment changes in the study area from 1988 to 2014, the authors selected five Landsat images acquired in 1988,1996, 2002, 2009, 2014 respectively to generate the land cover classification maps by using multiple classifier system and the remote sensing based ecological index (RSEI)maps by using RSEI. The change of land cover and ecological environment in the study area was obtained by the method of post classification change detection. Some conclusions have been reached:① The land cover of the study area significantly changed during the 26 years from 1988 to 2014,and the forest,shrub and grassland and built-up land increased rapidly, while farmland,degraded land and cultivation land decreased considerably;②RSEI is suitable for the evaluation of the ecological environment of the World Heritage Hakka Tulou;③The overall ecological quality of the two study areas improved year by year except for the period of 1988―1996; ④ The relationship between the land cover and the ecological environment revealed that the ecological quality improved in the degraded land at high -altitude,the slope farmland which was converted into the forest land, shrub and grassland, and became worse in the area of forest, shrub and grassland land which degraded into the area of farmland, the degraded land and the reclaimed land as well as the expansion area surrounding the urban district.关键词
