The construction of the Three g.rg.s Dam on the Yang.ze River has extensive impact on the ecosystems and the population of the Three g.rg.s Area （Tg.）. Inundation and resettlement have induced far-reaching.land use and land cover chang. （LUCC）. The areas that are affected by measures of resettlement are in a tense situation between the implementation of various g.vernmental tasks addressing.sustainable land use and water retention and the fulfilment of the population＇s economic needs, which primarily depend on ag.icultural 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, g.olog. and hydraulic influences. In this study, supervised classifications are performed using.Landsat-TM （1987 and 2007） and ASTER （2007） imag.s. LUCC is assessed by post-classification chang. analysis. On the catchment scale, arable land has decreased sig.ificantly, while g.rden land （citrus orchards） and woodland have increased. LUCC mainly affects the area surrounding.the reservoir （＂backwater＂） of the Xiang.i （香溪） River, driven by local resettlement, newly built infrastructure, relocation of land cultivation, and conversion of arable land to g.rden land. In the hinterland, LUCC occurs in form of abandonment of land cultivation as a consequence of the g.ain-forg.een prog.amme.
