With the fast development of socio-economic in rapidly urbanized region, more attention has been focused on the property of natural resources and environmental benefits. In this regard, ecological property, which is considered as one of the most significant resource and wealth in a country, has being concerned gradually in recent years. Dynamics of land use/cover at a wide range of scales throughout the world will inevitably result in various effects on the structure and function of ecological systems, with ecological property changing obviously and profoundly. With those reasons discussed above, the assessment of ecological property should be paid more attention, which will be useful for the sustainable development in rapidly urbanized region. In this paper, based on the theory of geography and ecology, with the aid of remote sensing data sources and GIS technology, we attempted to quantify the spatial and temporal dynamics of ecological property in Dongguan city, which experienced the fastest socio-economic development in Guangdong Province in the past two decades. The results showed that ecological property in Dongguan city changed prominently since 1988, with high and low values of property transforming frequently. The number of towns with per unit area ecological property decrease increased obviously, and most of these towns are located in the rapid economic developed areas of central and northern Dongguan. Per capita ecological property also decreased obviously with the lowest value in 1996.
