1Land Use Change and Causes in the Xiangxi Catchment, Three Gorges Area Derived from Multispectral Data显示文摘The construction of the Three Gorges Dam on the Yangtze River has extensive impact on the ecosystems and the population of the Three Gorges Area (TGA). Inundation and resettlement have induced far-reaching land use and land cover change (LUCC). The areas that are affected by measures of resettlement are in a tense situation between the implementation of various governmental tasks addressing sustainable land use and water retention and the fulfilment of the population’s economic needs, which primarily depend on agricultural production. Destabilization of slopes and soil erosion are immediate hazards induced by the impoundment. Farming is a very important source of income and has to persist on the one hand to assure the income of the rural population. On the other hand, the environment has to be protected from runoff, soil erosion and instabilities connected to relief, geology and hydraulic influences. In this study, supervised classifications are performed using Landsat-TM (1987 and 2007) and ASTER (2007) images. LUCC is assessed by post-classification change analysis. On the catchment scale, arable land has decreased significantly, while garden land (citrus orchards) and woodland have increased. LUCC mainly affects the area surrounding the reservoir ('backwater') of the Xiangxi ( 香溪 ) River, driven by local resettlement, newly built infrastructure, relocation of land cultivation, and conversion of arable land to garden land. In the hinterland, LUCC occurs in form of abandonment of land cultivation as a consequence of the Grain-forGreen programme.Christoph Seeber Heike Hartmann 项伟 Lorenz King 2010Journal of Earth Science2010,21,6:12

6Spatio-temporal changes of exposure and vulnerability to floods in China显示文摘A socio-economic data set on China's historical flood losses for the period 1984e2012 was compiled to analyze the exposed population,economy,and crop area as well as the vulnerabilities of the population and economy to floods.The results revealed that the exposed population was approximately 126 persons km 2per year when taking China as a whole;in terms of the economy,potential losses due to floods were estimated to be approximately 1.49 million CN$km 2and the crop area exposed to floods covered 153 million hm2per year.China's total exposure to floods significantly increased over the analysis period.The areas that showed the higher exposure were mainly located along the east coast.The population's vulnerability to floods showed a significantly increasing trend,however,the economic vulnerability showed a decreasing trend.The populations and economies that were most vulnerable to floods were in Hunan,Anhui,Chongqing,Jiangxi,and Hubei provinces.The municipalities of Shanghai,Beijing,and Tianjin showed the lowest vulnerabilities to floods.WANG Yan-Jun GAO Chao ZHAI Jian-Qing LI Xiu-Cang SU Bu-da HARTMANN Heike 2014Advances in Climate Change Research2014,5,4:1
